The pituitary is an endocrine (hormone-producing) gland that sits just beneath the base of the brain, behind the bridge of the nose. It is very small – only about the size of a pea. The pituitary gland is very important as it takes messages from the brain (via a gland called the hypothalamus) and uses these messages to produce hormones that affect many parts of the body, including stimulating all the other hormone-producing glands to produce their own hormones. For this reason it is often referred to as the ‘master gland’.

The pituitary gland has two parts. The anterior (or front) pituitary produces hormones that affect the breasts, adrenals, thyroid, ovaries and testes, as well as several other hormones. The main glands affected by the posterior (or rear) pituitary are the kidneys.

The pituitary gland is sometimes called the "master" gland of the endocrine system because it controls the functions of many of the other endocrine glands. The pituitary gland is no larger than a pea, and is located at the base of the brain. The gland is attached to the hypothalamus (a part of the brain that affects the pituitary gland) by nerve fibers and blood vessels. The pituitary gland itself consists of 2 major structures:Anterior lobe

Posterior lobe

thankyou so so so 🙂🙂🙂🙂🙂😊😊😊 much

Ans may be progesterone

Because during exercise our body releases more energy by the process of respiration , so we often get tired during exercise

Glucagon is ahormonethat is involved in controllingblood sugar(glucose)levels. It is produced by the alpha cells, found in the isletsofLangerhans, in the pancreas, from where it is released into thebloodstream. ... Itpromotes the productionof glucosefrom amino acid molecules.

glucagon hormone regulates sugar level in our body . And secreted from pancrease.

thanks brother but i want an answer for the 1st one

Vegetative propagation, or vegetative plant propagation, refers to the process of plant reproduction whereby a fragment of a parent plant (a cutting) is taken in order to produce more plants (clones). These fragments, known as cuttings, are able to take root and grow into full plants without much interference from the gardener.

In most cases, the vegetation used in vegetative plant propagation is derived from the roots, stems, and leaves of a gardener's healthiest, highest-yielding plant, commonly referred to as the mother plant.

Many indoor growers refer to vegetative plant propagation simply as cloning, or taking cuttings. It is considered to be an asexual method of plant propagation.

Advantages:(i)Bear flowers and fruits earlier than those produced from seeds.(ii)Plants without seeds can also reproduce.(iii)Genetically similar to the parent plant.(iv) only one parent is requried

Thank u very much

vegetative reproduction is type of asexual reproduction in that gametes not participate and fusion not takes place ,example (1) rhizomes is ginger (2) bulbil in agave

(i) With the advent of printing press a new reading public emerged. The books became cheaper as printing technology reduced the cost of production.(ii)As books flooded the market, readership increased and books now reached to larger number of people.(iii)Access to books created a new reading culture. Earlier reading was restricted to the elite only- common people lived in world of word culture who heard sacred text read out to them or ballads recited or folk tales narrated.(iv)Now a reading public came into being. But book could be read only by literate people, keeping this point of view, printers published popular ballads and folk tales with lot of pictures which could be read to illiterate public. These ballads, tales could then be sung or read out to those who could not read.(v)Thus printed material could be orally transmitted at gatherings and taverns. Reading public and hearing public thus got intermingled.

Membrane biogenesis is the process which involves the synthesis of cell membrane with the help of proteins and lipids. Endoplasmic reticulum is responsible for the synthesis of these membranes.

Membranes synthesised by this process of membrane biogenesis help in dividing the cell into structural and functional compartments. Membranes of the cell altogether are called as endomembrane system. The endomembrane system includes different membranes suspended in the cytoplasm and the plasma membrane.

Biodiversity generally refers to the variety and variability of life on Earth. According to the United Nations Environment Programme, biodiversity typically measures variation at the genetic, species, and ecosystem level.

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensuresnaturalsustainability for all life forms.

by making ourselves sincere towards the conservation of biodiversity

With a few simple habit changes and pro-active actions,you can reduceyour adverse impact on the environment and encourage localbiodiversity.

Help Native Pollinators. ...

Reduceor eliminate pesticides and fertilizer. ...

Restore habitat in your yard. ...

Restore habitat in your community. ...

Reduceyour consumption.

The main cause of loss of biodiversity is the greed of human..when our need turns into greed..the loss of biodiversity occurs..we can prevent it by following methods...1-Do not use plastic objects..it effect the river bodies..2-Avoid the use of chemical fertilizer in farms..they destroy the helpful Organisms of farmland..3-Avoid cutting tress...Plant more tress..

As an individual I can prevent the loss of diversity in following ways:-- Conservation: 1) conserving the available resources.- Control:1) preventing the harm.2) stopping the harmful activities.3) changing the mind set.- Production:1) attempting innovation.2) revival of harm factors of environment.- Awareness:1) education.2) guidence.3) immitation.4) organisation.5) participation.- Prevention:1) preventing possible harms.2) designing new plans.3)factors harmful to environment.- Preservation:1) preserving the natural resources which are left.2) remedies to prevent further loss.3) preserving unknown regions.

multiple fission occur in plasmodium

multiple fission occurs in plasmodium ....where The cyst breaks open

Haplontic life cycle can be defined as the zygotes which undergo meiosis to produce haploid spores to produce haploid individual.

Binary fission, asexual reproduction by a separation of the body into two new bodies.

In theprocess of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.

Asister chromatidis either one of the twochromatidsof the same chromosome joined together by a common centromere. Non-sister chromatids, on the other hand, refers to either of the twochromatidsof pairedhomologous chromosomes, that is, the pairing of a paternal chromosome and a maternal chromosome.

thank you very much

option 1 is the answer

thank you .please answer my more question s

The above symbol means The substance is combustible.In simple words the substances catches fire easily.

The disaster which may occur is fire accident.

Given, power of pump = 2kW =2000W

Time (t)= 60sec

Height (h) = 20m

g = 10m/s2

As you know, power =work done per unit time.

Work done = mgh = m ×10×20 =200m

Therefore, 2000W = 200m/60s

Therefore, m = 600kg

So, the pump can raise 600kg of water in one minute.

The uppermost layer of soil is very fertile and rich in humus. The main threat to top soil is soil erosion. Soil erosion is loss of soil due to wind or water flow. Loss of top soil can be prevented by stoppmg soil erosion by following methods (i) Afforestation (ii) strip cropping (iii) By following crop rotation to maintain the fertility of soil. (iv) Proper drainage and irrigation arrangements.
