What are the advantages of anaerobic respiration in living beings |
| Answer» \tLiving beings is that it do not require use of oxygen to get get energy from food. It also happens in our body some time when there is lack of oxygen in us. ( Very Rarely !) and also it produce only 2 ATP.\tAnother advantage of anaerobic respiration is its speed. It produces ATP very quickly. For example, it lets your muscles get the energy they need for short bursts of intense activity (see Figure below). Aerobic respiration, on the other hand, produces ATP more slowly.\xa0 | |

Types of biodiversity |
| Answer» Biodiversity further classifies into three major types. They are:\tGenetic Diversity: It is basically the variety of species expressed at the genetic level by each individual in a species. No two individuals belonging to the same species are exactly similar. For example, in the species of human beings, each human shows a lot of diversity in comparison to another human. People living in different regions show a great level of variation.\tSpecies Diversity : It is the biodiversity observed within a community. It stands for the number and distribution of species. The number of species in a region varies widely depending upon the varied environmental conditions. For example, it is usually observed that civilizations residing beside water bodies show more species than the one compared to the areas away from water bodies.\tEcological Diversity: It defines the diversity observed among the ecosystems in a particular region. Different ecosystems like mangroves, rainforests, deserts, etc., show a great variety of life forms residing in them. | |

Explain the translocation in plants with the help of a diagram |
| Answer» The transport of food from the leaves to other parts of the plant is called translocation. Phloem tissue transports the food from the leaves to the other parts of the plant. The movement of food in phloem takes place by utilising energy. The sugar made in the leaves is loaded into the sieve tubes of phloem by using ATP. Water enters the sieve tube containing sugar which causes high pressure and pushes the food to all the parts of the plant having low pressure. This is how the food is transported according to the needs of the plant. | |

Explain the life cycle of angiosperms |
| Answer» The adult, or sporophyte, phase is the main phase of an angiosperm’s life cycle. As with gymnosperms, angiosperms are heterosporous. Therefore, they generate microspores, which will produce pollen grains as the male gametophytes, and megaspores, which will form an ovule that contains female gametophytes. Inside the anthers’ microsporangia, male gametophytes divide by meiosis to generate haploid microspores, which, in turn, undergo mitosis and give rise to pollen grains. Each pollen grain contains two cells: one generative cell that will divide into two sperm and a second cell that will become the pollen tube cellThe ovule, sheltered within the ovary of the carpel, contains the megasporangium protected by two layers of integuments and the ovary wall. Within each megasporangium, a megasporocyte undergoes meiosis, generating four megaspores: three small and one large. Only the large megaspore survives; it produces the female gametophyte referred to as the embryo sac. The megaspore divides three times to form an eight-cell stage. Four of these cells migrate to each pole of the embryo sac; two come to the equator and will eventually fuse to form a 2n polar nucleus. The three cells away from the egg form antipodals while the two cells closest to the egg become the synergids. | |

How can we define ATP in simple way??? |
| Answer» It may help you :Adenosine Triphosphate (ATP) is an energy carrying molecule found in all living cells. An ATP molecule comprises of different components like adenine, ribose and three phosphates linked in a chain. The phosphates are linked by high energy phosphate bonds. Hence, ATP on dephosphorylation by ATPases yields energy. Energy is released due to breaking up of high energy phosphate bonds. Energy released by ATP is used to carry out different metabolic reactions of the body. | |

☆ Define Glomerular Filtration Rate (GFR) ? |
|
Answer» Glomerular filtration rate (GFR) is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood. thanks frnds☺☺ The amount of the filtrate formed by the kidneys per minute is called glomerular filtration rate (GFR). The value of GFR in a healthy individual is approximately 125 ml/minute i.e., 180 litres per day The amount of filtrate formed by kidney per minute is called Glomerular Filtration Rate (GFR) |

Notes of human respiratory system |
|
Answer» 3. Larynx: It is a chamber situated in the region of neck. It is supported by four cartilages : thyroid is the largest and in the form of a broad ring incomplete dorsally, cricoid is a complete ring lying at the base of thyroid, a pair of arytenoids lying above the thyroid but in front of cricoid, and epiglottis situated behind the tongue that serves to cover the entrance to the trachea so that food particles may not enter into it. Larynx is also known as voice box since it helps in the production of sound. 4. Trachea: It is a tube starting from larynx running through the neck and the thoracic cavity. The trachea runs through the neck in front of the oesophagus. The trachea or windpipe is about 12 cm long and divided into two bronchi in the thoracic region. 5. Bronchi and bronchioles: The two bronchi enter into right and left lungs of either side. Inside the lungs they further branch into many smaller bronchioles with a diameter of about 1 mm. These bronchioles further divide into terminal and then into respiratory bronchioles. Each respiratory bronchiole divides into a number of alveolar ducts that further divide into atria, which swell up into air sacs or alveoli. 6. Lungs: A pair of conical shaped lungs is situated in the double walled sacs called pleural cavities. They are spongy and richly supplied with blood vessels and capillaries. They have about 300-400 millions of alveoli through which exchange of gases occur. Lungs have various bronchioles ending into alveoli where exchange of gases occurs. The alveoli are thin walled pouches the walls of which have epithelial linings supported by basement membrane.I hope my answers help U ☺☺☺☺ All mammals have lungs for the purpose of respiration. This is known as pulmonary respiration. The mammalian respiratory system consists of the nasal cavity, nasopharynx, larynx, trachea, bronchi, bronchioles and lungs. 1. Nasal cavity: It is a large cavity lying dorsal to the mouth and is lined by mucous secreting epithelium. The nasal cavity opens outside through a pair of external nostrils or nares. Bones and cartilages support the nasal cavity. The nasal cavity is divided into two parts by a nasal septum. The cavity opens inside into pharynx through two internal nostrils. Air while passing through the nasal cavity is filtered, and only the clean air free from dust particles and foreign substances enters the pharynx. The air also gets warmed and moistened in this chamber. It is important to note that air can also be inhaled through mouth directly, but this is not advisable because the air will not be filtered, warmed and moistened. This gradually will harm the respiratory system. 2. Nasopharynx: It is a chamber situated behind the nasal cavity. At the level of soft palate, it becomes continuous with the mouth cavity or oral pharynx. It also receives the openings of eustachian tubes on its lateral sides and is thus connected to the middle ear. U can take help of neela bakore tutorials.......i m sure u will like it..... |

What means of cell |
|
Answer» cell is the structural and functional unit of life. Cells are the basic unit bounded by the membrane that consists of the fundamental molecules of life of which all living organisms are made up of. Cell Biology encompasses everything about cells from its basic structure to the functions of every cell organelle. A single cell is an organism in itself such as yeast or bacterium; other cells gain special functions soon after they mature. These acquire unique functions as they mature. Cell is the fundamental structural and functional unit of all living organisms |

What will happen if you inject air in your veins with a syringe? |
|
Answer» The death part is what I\'ve been wondering about. So this is the reason why doctors spray some fluid in the open before injecting inside the patient..... or am I wrong? Tiny air bubbles go into IV fluids all the time without consequence. Some air can get injected during CT scans or medication pushes (see CT images in another answer). These small amounts float along until they find a good place to rest or reach the lung. The gasses are absorbed into the blood and they disappear.If a larger amount of air is injected at once, you get air instead of blood flowing through the veins. When this reaches the right heart, you get a beating right ventricle sloshing around bubbles instead of blood, and cardiac output goes to zero just as if the heart had stopped. The patient dies suddenly. |

Ring str of glucofuranose |
| Answer» A\xa0furanose\xa0is a collective term for carbohydrates that have a chemical structure that includes a five-membered\xa0ring\xa0system consisting of four carbon atoms and one oxygen atom. The name derives from its similarity to the oxygen heterocycle furan, but the\xa0furanose ring\xa0does not have double bonds.\xa0Cyclic sugars that contain a five membered ring are called "furanoses". The term is derived from the similarity with the aromatic compound furan and tetrahydrofuran. Cyclic sugars that contain a six membered ring are called "pyranoses" The term is derived from the similarity with the compound pyran and tetrahydropyran. | |

Explain the type of cell junctions... |
| Answer» In vertebrates , there are 3 main types of cell junctions.a) TIGHT JUNCTIONS help to stop substances from leaking across a tissue. Tight junctions seal adjacent epithelial cells in a narrow band just beneath their apical surface .They limit the passage of molecules and ions through the space between the cells. b) ADHERING JUNCTIONS perform cementing to keep neighbouring cells together.c) GAP JUNCTIONS ( communicating junctions,) they directly connect the cytoplasm of the two cells , which allows various Molecules ,ions and electrical impulses to directly pass through a regulated gate between cells. | |

describe modification of stem |
| Answer» Modification for food storage: The underground stems of potato, ginger, turmeric, zamikand, Colocasia, etc. are modified for food storage. Such modifications are the tools of perenation to tide over unfavourable conditions.Modifications for climbing: In some plants, stem tendrils develop form axillary buds. These are slender and spirally coiled structures. A tendril helps the plant to climb to a support, e.g. cucumber, pumpkin, grapevine, etc.Modification for defence: In some plants, the axillary buds are modified into woody, straight and pointed thorns. Such thorns protect the plant from browsing animals, e.g. Citrus, Bougainvillea.Modification for photosynthesis: In some plants of arid regions, the stems are modified into flattened or fleshy cylindrical structures. The flattened structure can be seen in Opuntia and the cylindrical structure can be seen in Euphorbia. Such structures contain chlorophyll and photosynthesis happens in them.Modification for vegetative propagation: Stems are modified for vegetative propagation in many plants, e.g. grass, berry, dahlia, etc. | |
