Deficiencies in any of the hormones mentioned above can cause illness, which vary in gravity. Starting with the posterior lobe, a deficiency of ADH will increase our thirst and urination. A lack of prolactin will quite predictably lead to an inability to lactate, which to this day cannot be treated. TSH deficiency has symptoms similar to those from a compromised thyroid gland, which includes fatigue, memory loss, and bodily weakness. A lack of LH or FSH will result in a decrease in libido, irregular menses, erectile dysfunction, and mood changes. ACTH deficiency will cause nausea, body aches, poor appetite, and even low blood sugar and pressure. Lastly, deficiency growth hormone will lower muscle mass and bone density, which has long term ramifications on the quality of our lives.

An overproduction of hormone has its own consequences. Too much growth hormone can lead to gigantism and acromegaly, or too much growth of bones and soft tissues leading to heart issues and sleep apnea. Too much TSH will result in shakiness, irritability, and high blood pressure. Too much prolactin will cause inappropriate expression of breast milk that can occur in women or men, and a weakening of bones. Excess ACTH will cause weight gain among brittle bones and mood instability. Lastly, excess FSH and LH are linked to infertility and irregular menstruation.

The most common type of pituitary gland disorder, however, are tumors. The grand majority of pituitary tumors are benign, or just a noncancerous swelling in the gland that may not cause any symptoms and may never be symptomatic. Unlike many types of tumors, most people afflicted with pituitary tumors have no prior family history of issues with the pituitary gland and is not usually genetically inherited. One of these exceptions is multiple endocrine neoplasia (or MEN) which is a set of inherited disorders that lead the body’s endocrine glands, including the pituitary gland, to overexpress hormones. But pituitary tumors, specifically, still remain by and large benign.

Tumors on the Pituitary GlandVarious types of pituitary tumors exist. In general, people with a pituitary gland tumor will experience a series of telltale symptoms. Most will have vision problems, headaches, menstrual changes, infertility, mood changes, fatigue, and even Cushing’s syndrome – which has its own set of symptoms including, but not limited to, high blood pressure and weight gain secondary to too much ACTH release.

The most common type of pituitary tumor is called a “non-functioning” tumor. The name derives from its inability to make hormones. These patients will have issues with their vision and headaches. Furthermore, pituitary tumors can be divided into three groups according to their problematic actions.

Hypersecretion refers to the making of too much hormone, and this is an issue afflicted by a secretory pituitary tumor. Hyposecretion, in contrast, is too little hormone production and is normally caused by a large pituitary tumor that will physically block the pituitary gland from making hormone. It can also result from surgical resection of a tumor. Lastly, tumor mass effects are the issues that arise from a growing pituitary tumor that is pressing against the pituitary gland and may result in compromised vision and headaches, as well.

Other pituitary conditions worth noting include craniopharyngioma. This is a type of cyst or tumor that is congenital, meaning it is present at birth. It can swell and fill with fluid, and may cause headaches and vision issues as well as sleep issues. ESS, or empty sella syndrome is a disorder that arises from an affliction in the bony structure that encases the brain and surrounds the pituitary. A primary ESS will be a small defect that give rise to high pressure in the bony base that causes the gland to flatten. This is linked to high blood pressure and obesity in females. On the other hand, secondary ESS will result from surgery or an injury that has caused the pituitary gland to regress. The symptoms will be related to pituitary function loss, such as infertility and fatigue.

The following hormones are made in the anterior (front part) of the pituitary gland:

Prolactin - stimulates breast milk production after childbirth. It also affects sex hormone levels from ovaries in women and from testes (testicles) in men, as well as fertilityGrowth hormone (GH) - stimulates growth in childhood and is important for maintaining a healthy body composition and well-being in adults. In adults, GH is important for maintaining muscle mass and bone mass. It also affects fat distribution in the body. Read about growth hormone excessAdrenocorticotropin (ACTH) - stimulates the production of cortisol by the adrenal glands—small glands that sit on top of the kidneys. Cortisol, a "stress hormone," is vital to our survival. It helps maintain blood pressure and blood glucose (sugar) levels, and is produced in larger amounts when we’re under stress—especially after illness or injury. Read about having too much ACTHThyroid-stimulating hormone (TSH) - stimulates the thyroid gland to produce thyroid hormones, which regulate the body's metabolism, energy balance, growth, and nervous system activityLuteinizing hormone (LH) - stimulates testosterone production in men and egg release (ovulation) in womenFollicle-stimulating hormone (FSH) - promotes sperm production in men and stimulates the ovaries to produce estrogen and develop eggs in women. LH and FSH work together to enable normal function of the ovaries and testesThe following hormones are stored in the posterior (back part) of the pituitary gland:

Antidiuretic hormone (ADH) - also called vasopressin, regulates water balance in the body. It conserves body water by reducing the amount of water lost in urineOxytocin – causes milk to flow from the breasts in breastfeeding women, and may also help labor to progressPituitary Tumors

The most frequent type of pituitary disorder is a pituitary gland tumor. These tumors are fairly common in adults. They are not brain tumors and are almost always benign (that is, not cancer). In fact, cancerous tumors of this sort are extremely rare.

There are two types of tumors—secretory and non-secretory. Secretory tumors produce too much of a hormone normally made by the pituitary, and non-secretory tumors do not. Both types of tumors can cause problems if they are large and interfere with normal function of the pituitary gland and/or nearby structures in the brain.

The problems caused by pituitary tumors fall into three general categories:

Hypersecretion - too much of any hormone in the body is caused by a secretory pituitary tumorHyposecretion- too little of any hormone in the body can be caused by a large pituitary tumor, which interferes with the pituitary gland’s ability to produce hormones. Hyposecretion can also result from surgery or radiation of a tumorTumor mass effects - as a pituitary tumor grows and presses against the pituitary gland or other areas in the brain, it may cause headaches, vision problems, or other health effects

Ants are exceptionally fascinated with sweets and have a sharp feeling of following honeydew and sugar.( antennae are unique organs of smell, touch, taste, and hearing for the ants).

Desserts supply vitality for different activities of ants.

They can smell it using their reception apparatuses, which can recognize minute scents.

They likewise have scouts checking for sustenance, so when one insect finds the treat and takes a piece back home it will leave a compound trail alternate ants can take after.

The ants that take the trail and discover the treat toward the end add to the trail and make it more grounded, so more ants land until all the food is gone.

1. Ponds donot needed to be cleaned but aquarium needs to be cleaned. This is because aquarium do not contain soil and decomposing bacteria which helps in degrading complex organic substance into simple inorganic substance and act as a cleaner . But pond have this facility. Therefore, it do not needed to be cleaned whereas ponds do.

पारिस्थितिकी (इकोलॉजी)जीवविज्ञान की एक शाखा है जिसमें जीव समुदायों का उसके वातावरण के साथ पारस्परिक संबंधों का अध्ययन करतें हैं। प्रत्येक जन्तु या वनस्पति एक निश्चित वातावरण में रहता है। पारिस्थितिज्ञ इस तथ्य का पता लगाते हैं कि जीव आपस में और पर्यावरण के साथ किस तरह क्रिया करते हैं और वह पृथ्वी पर जीवन की जटिल संरचना का पता लगाते हैं।

पारिस्थितिकी को एन्वायरनमेंटल बायोलॉजी भी कहा जाता है। इस विषय में व्यक्ति, जनसंख्या, समुदायों और इकोसिस्टम का अध्ययन होता है। इकोलॉजी अर्थातपारिस्थितिकी जर्मन शब्द (Oekologie) का प्रथम प्रयोगजर्मन जीव वैज्ञानिक अर्नेस्ट हैकलने अपनी पुस्तक “जनरेल मोर्पोलॉजी देर ऑर्गैनिज़्मेन” में किया था।

बीसवीं सदी के आरम्भ में मनुष्य और उसके पर्यावरण के बीच संबंधों पर अध्ययन प्रारंभ हुआ और एक साथ कई विषयों में इस ओर ध्यान दिया गया। परिणामस्वरूप मानव पारिस्थितिकी की संकल्पना आयी।

प्राकृतिक वातावरण बेहद जटिल है इसलिए शोधकर्ता अधिकांशत: किसी एक किस्म के प्राणियों की नस्ल या पौधों पर शोध करते हैं। उदाहरण के लिए मानवजाति धरती पर निर्माण करती है और वनस्पति पर भी असर डालती है। मनुष्य वनस्पति का कुछ भाग सेवन करते हैं और कुछ भाग बिल्कुल ही अनोपयोगी छोड़ देते हैं। वे पौधे लगातार अपना फैलाव करते रहते हैं।

पारिस्थितिकी तंत्र

पौधे, जीव-जन्तु एवं भौतिक पर्यावरण को सामूहिक रूप से ‘पारिस्थितिक तंत्र’ कहा जाता है। पारिस्थितिकी वह विज्ञान है, जो किसी क्षेत्र में रहने वाले विभिन्न जीवों के परस्पर सम्बन्धों एवं भौतिक पर्यावरण से उनके सम्बन्धों का अध्ययन करता है। संक्षेप में, पारिस्थितिकी के अन्तर्गत जीवों तथ उनके पर्यावरण के बारे में अध्ययन किया जाता है। इसके कई उपविभाग हैं, जैसे- प्राणि पारिस्थितिकी, पादप पारिस्थितिकी, जैव पारिस्थितिकी, उत्पादन पारिस्थितिकी, समष्टि पारिस्थितिकी एवं स्वपारिस्थितिकी आदि।

विविध प्रकार के वातावरण में भिन्न-भिन्न प्रकार के जीव पाए जाते हैं। सभी जीव, अपने चारों ओर के वातावरण से प्रभावित होते हैं। सभी जीव अपने वातावरण के साथ एक विशिष्ट तंत्र का निर्माण करते हैं, जिसे पारिस्थितिकी तंत्र कहते हैं। जीवों और वातावरण के इस संबंध को पारिस्थितिकी कहा जाता है।

सन् 1965 में ओड़म ने पारिस्थितिकी के लिए प्रकृति की संरचना तथा कार्यों का अध्ययन नाम नई परिभाषा दी।विभिन्न वैज्ञानिकों ने पारिस्थितिकी तंत्र की भिन्न-भिन्न परिभाषाएं दी हैं। सबसे सरल परिभाषा है, ‘प्राणियों एवं वनस्पतियों के परस्पर संबंधों और इनके पर्यावरण से संबंधों का अध्ययन।’

इको-सिस्टम या पारिस्थितिक तंत्र क्या है? इसे समझने के लिए हम कल्पना करें एक तालाब की, जहां मछलियां, मेंढ़क, शैवाल, जलीय पुष्प और अन्य कई जलीय जीव रहते हैं। ये सभी न केवल एक-दूसरे पर आश्रित हैं, अपितु जल, वायु, भूमि जैसे अजैविक घटकों के साथ भी पारस्परिक रूप से जुड़े हुए हैं। समुदाय का यह पूर्ण तंत्र, जिसमें अजैविक घटकों तथा जैविक घटकों का पारस्परिक संबंध ही पारिस्थितिकी तंत्र का निर्माण करता है।

पारिस्थितिक तंत्र के मुख्यतः दो प्रकार के संघटक होतें है –

1. जैविक कारक2. अजैविक कारक

जैविक कारक

• जन्तु समुदाय

• वनस्पति समुदाय

• सूक्ष्मजीव

• मनुष्य

अजैविक कारक

• प्रकाश

• ताप

• आर्द्रता

• हवा

• स्थलाकृति

• मृदा

विविध प्रकार के वातावरण में भिन्न-भिन्न प्रकार के जीव पाए जाते हैं। सभी जीव, अपने चारों ओर के वातावरण से प्रभावित होते हैं। सभी जीव अपने वातावरण के साथ एक विशिष्ट तंत्र का निर्माण करते हैं, जिसे पारिस्थितिकी तंत्र कहते हैं। जीवों और वातावरण के इस संबंध को पारिस्थितिकी कहा जाता है।

अपने टैंक को साफ करना और अपना पानी बदलना महत्वपूर्ण है क्योंकि यह सब कुछ साफ करता है जिसे आप नहीं देख सकते हैं जो आपकी मछली के लिए हानिकारक हो सकता है। महीने में कम से कम एक बार आपको टैंक के किनारों से अतिरिक्त शैवाल को हटाने के लिए बजरी और एक स्पंज या खुरचनी को साफ करने के लिए एक मछलीघर वैक्यूम का उपयोग करना चाहिए।

Please like the solution 👍 ✔️

तालाब भी एक पारिस्थितिक तंत्र है इसलिए इसकी सफाई आवश्यक नहीं है क्योंकि वहां पर उपस्थित जीव जंतु अपने आप ही इस तालाब की सफाई का काम करते हैं यह पूरा एक प्रक्रिया है जो की निरंतर चलती रहती है यह एक तरह का इको सिस्टम डिजाइन करती है अतः में तालाब को साफ करने की आवश्यकता नहीं होती है उसमें देने वाले जीव जंतु ही इस प्रक्रिया को कर लेते हैं

In cockroach respiration occurs by a special part calledtrachea. It is a tube like structure that opens out of the body through a minute hole called spiracle. There are several spiracles present on both side of the body of cockroach. Through the spiracles air enters inside the trachea where exchange of gases takes place.

Some examples of reptiles are turtles, tortoises, lizards, snakes, crocodiles, and dinosaurs (now extinct). The study of amphibians and reptiles is called Herpetology and a person who studies reptiles and amphibians is a Herpetologist.

The circulatory system is centred on theHEART, a muscular organ that rhythmically pumpsBLOODaround a complex network ofBLOOD VESSELSextending to every part of the body. Blood carries the oxygen and nutrients needed to fuel the activities of the body’s tissues and organs, and it plays a vital role in removing the body’s waste products. An average-sized adult carries about 5 litres (9 pints) of blood.All the output of blood from the left side of the heart goes into the aorta, the body’s largest artery. Other arteries branch from the aorta to supply blood to the head, limbs, and internal organs. The blood is drained from all these parts by veins into two large vessels, the inferior and superior venae cava, which deliver the blood back to the right side of the heart.

HEART

The heart contracts tirelessly – more than 2.5 billion times over an average lifetime – to pump blood around the body. These contractions are triggered by electrical impulses that originate in a specialized area of heart tissue. The signals spread through the muscle in the wall of the heart via a network of conducting fibres.

INSIDE THE HEART

The heart has two upper chambers, called atria, and two lower chambers, called ventricles. Blood from the body arrives in the right atrium. This blood is low in oxygen, and is shown here in blue. The blood passes to the right ventricle, which pumps it to the lungs to pick up more oxygen. The left atrium receives oxygen-rich blood (red) back from the lungs. This passes to the left ventricle, which pumps it by way of the aorta to the body.

HEART VALVES

At the exit of each heart chamber lies a valve, which ensures the one-way flow of blood through the heart and into the circulation. These valves are made of flaps that open to allow blood to pass through but snap tightly shut to prevent backflow. The valves have three flaps, except for the valve between the left atrium and left ventricle, which has two.

BLOOD VESSELS

If an adult’s blood vessels were laid end to end, they would stretch out over 100,000 km (62,500 miles). There are three main types of vessel. Arteries carry blood from the heart to the body’s tissues, while veins carry blood back from the tissues to the heart. Small arteries are called arterioles and small veins are referred to as venules. The third and smallest type of vessel, capillaries, form a network connecting the smallest arterioles with the smallest venules.

China has stepped up its overseas aid massively in recent years, a trend that has seen the China Development Bank become the world's largest lender. China invested in agriculture to reduce poverty and successful agricultural projects were built up from the grass roots. These were not top-down solutions.

"The Chinese government and World Food Programme selected the successful agricultural projects and implemented them throughout the nation. Think of the soft power China would gain if it focused this ability and exported it. African and Southeast Asian governments are negotiating with Beijing for Chinese participation in agricultural projects.

It helps China have a positive image across all strata of society, not just the top leadership [in these countries]. To protect China's interests and those of Chinese citizens abroad, it's in China's interest to invest in soft infrastructure in developing countries.

Clearandtransparent wateris notalways fitfordrinking.Watermight appearclean, but it may contain some disease causing micro-organisms and other dissolved impurities. Hence, it is advised to purifywaterbeforedrinking. Purification can be done bywaterpurifying systems or by boiling thewater.

No,the clear or transparent water are not fit for drinking because the water contain many impurities or the micro organism which can't be seen from our naked eyes so that's why doctors or our elders suggest us to take boil water or filter water.

due to the balanced pH of that water the clear. But the transparent water is not possible to be achieved here but according to question the pH is balance of that clear and transparent water

Thespinal cordconnects the brain to nerves throughout the body. Thespinal cordis a long, thin, tubular structure made up of nervous tissue, that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.

We know, when magnetic field is directly proportional to magnetic lines of force . Means if magnetic lines of force are more concentrated at a point respect to another point then that point have more magnetic field with respect to the point which contains less concentrated magnetic lines of force.

In case of circular loop, magnetic lines of force are highly concentrated at centre as shown in figure. so, magnetic field is strong at centre . While in case of circumference , magnetic field is weaker than centre.

The Major Functions of The Spinal Cord. The spinal cord's major functions include: Electrical communication. Electrical currents travel up and down the spinal cord, sending signals which allow different segments of the body to communicate with the brain.

Ans :-

Cell Elongation:Auxins promote elongation growth in young stems and coleoptiles.

Tropism – Responses to Stimulus of Light & Gravity:Auxin meditates the effect of light and gravity on plant growth.

Apical Dominance:It is commonly observed that apical bud of many vascular plants is very active in growth and lateral buds remain inactive.

Formation of Lateral Roots:Optimal auxin concentration in primaryrootinhibits elongation growth, but high level auxin levels stimulate initiation of lateral roots and adventitious roots.

Delay in Leaf Abscission:The shedding of leaves, flowers and fruits from the living plant is known as abscission.

Fruit Development:The auxin is involved in the regulation offruitdevelopment.

Bothaerobic and anaerobic respiration involvechemical reactions which take place in the cell to produce energy, which is needed for active processes.

Aerobic respirationtakes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The chemical equation is

C6H12O6+ 6O2→ 6CO2+ 6H2O (glucose + oxygen -> carbon dioxide + water).

Anaerobic respirationalso produces energy and uses glucose, but it produces less energy and does not require oxygen. This is useful in tissues which have a high energy demand such as in working muscles, in which there isnot enough oxygen to produce all the energy needed by using aerobic respiration alone. Anaerobic respirationtakes place in the cell cytoplasm and produces lactic acid.

The chemical equation isC6H12O6 -> 2C3H6O3 (Glucose -> Lactic acid).

The lactic acid then needs to be oxidised later to carbon dioxide and water afterwardsto prevent it building up. This process requires oxygen and therefore following anaerobic respiration there is oxygen debt in the cell, as oxygen is needed to break down the lactic acid produced.

C6H12O6+ 6O2→ 6CO2+ 6H2O + Energy.Aerobic respirationis the process of breaking up of glucose into carbon dioxide and water in the presence of oxygen with release of energy. Aerobic respiration takes place in almost all the animals.

Amoeba : We know that amoeba is a unicellular organism which lives in fresh water. This organism does not have a specialized organ to do the process of respiration. So in amoeba respiration takes place through its cell membrane also calledplasma membrane. Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process ofdiffusion. The oxygen gas diffused inside the body is used up by amoeba. In the body the oxygen gas absorbed is used to break down the complex food material into simple molecules. During these metabolic reactions in the body of amoeba the oxygen gas is converted into carbon dioxide gas. The carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion.

Hydra :

Well hydra has no specialized organs forrespiration but exchange of gases is carried ou' by entire bodyy surface. Oxygen and carbon dioxide diffuse from the body digestive system. Thus an efficient exchange is carried ou by enteron..

Respiration is the process of oxidation of food materials like glucose, Amino acids, fatty acids to water and carbon dioxide. Respiration does not require any external heat to carry on the process. Combustion is only done by applying external heat to the sugar molecule to burn.

Amoeba is a unicellular organism whereas hydra is a multicellular organism.

Amoeba reproduces by binary fission whereas Hydra reproduces by budding and regeneration.
