What is the rh grouping |
| Answer» It is the type a blood grouping...basically if a person having rh positive along with his own blood group and another having rh negative and if both get mixed then the one having rh negative will start forming antibodies against it and destroy all the erythrocytes of the blood which may even be fatal....to avoid this the person should be injected with anti rh antibodies...eg-the mixing of blood of a mother with the foetus. | |

Explain chemiosmotic hypothesis |
| Answer» According to the\xa0Chemiosmotic Hypothesis, in photosynthesis, ATP synthesis is linked to development of proton (H+) gradient across thylakoid membranes. The\xa0chemiosmotic hypothesis\xa0was proposed by Peter Mitchell. This\xa0hypothesis\xa0stated that a proton-motive force was responsible for driving the synthesis of ATP. In this\xa0hypothesis, protons would be pumped across the inner mitochondrial membrane as electrons went through the electron transfer chain. | |

Seed have almost no water hence they absorb water easily why |
| Answer» Imbibition is a special type of diffusion when\xa0water\xa0is\xa0absorbed\xa0by solids-colloids causing an enormous increase in volume. ... Imbibition is also diffusion since\xa0water\xa0surface potential movement is along a concentration gradient; the\xa0seeds\xa0and other such materials\xa0have almost no water hence they absorb water easily.\xa0When a\xa0seed absorbs water, it is called imbibition.\xa0Water\xa0enters the\xa0seed\xa0either through a tiny opening in the\xa0seed\xa0called the micropyle or through the\xa0seed\xa0coat. ... The scarred\xa0seed\xa0coat is permeable, allowing\xa0water\xa0to pass through and germination to begin. Other\xa0seeds\xa0require cold temperatures before they can germinate. | |

Difference between lipase and amylase |
| Answer» The pancreas produces amylase to break down carbohydrates in food into simple sugars. The pancreas makes lipase to digest fats into fatty acids. ... Some amylase and lipase can be found in saliva and in the stomach. However, most of the enzymes made in the pancreas are released into the small intestine. | |
| 967. |
Difference between lypase and amyalase. |
| Answer» Amylase\xa0and\xa0lipase\xa0are key digestive enzymes.\xa0Amylase\xa0helps your body break down starches.\xa0Lipase\xa0helps your body digest fats. The pancreas\xa0is\xa0a glandular organ that sits behind the stomach and produces digestive juices that empty into the small intestine.\xa0Lipase\xa0has higher sensitivity than\xa0amylase\xa0in diagnosing acute pancreatitis. Various studies and evidence-based guidelines recommend\xa0lipase\xa0as the only diagnostic marker. Eliminating co-ordering of both\xa0amylase\xa0and\xa0lipase\xa0will provide a significant cost reduction. | |

Difference b/w metaphase and anaphase |
| Answer» In metaphase, the microtubules of the spindle (white) have attached and the chromosomes have lined up on the metaphase plate. The chromosomes coil up, the nuclear membrane begins to disintegrate, and the centrosomes begin moving apart. Spindle fibers form and sister chromatids align to the equator of the cell. Sister chromatids separate. During anaphase, the sister chromatids are pulled apart and move toward opposite poles of the cell.\xa0Anaphase\xa0A is characterized by the shortening of kinetochore microtubules, which pulls the chromosomes toward the poles.\xa0During anaphase B, the two poles move farther apart, bringing the chromosomes with them into what will become the two daughter cells. | |

What is merisyematic |
| Answer» Meristematic tissues are growth tissues and found in the growing regions of the plant. According to their position in plant, meristems are apical, lateral and intercalary.\tApical meristem - Apical meristem is present at the growing tips of stems and roots and increases the length of the stem and the root.\tLateral meristem – Lateral meristems are found beneath the bark. The girth of the stem or root increases due to lateral meristem (cambium).\tIntercalary meristem - Intercalary meristem is the meristem at the base of the leaves or internodes (on either side of the node) on twigs. It increases the length of the organs such as leaves and internodes. | |

How many ATPs does 1 FADH releases?? |
| Answer» The net gain from one cycle is 3 NADH and 1 FADH2\xa0as hydrogen- (proton plus electron)-carrying compounds and 1 high-energy GTP, which may subsequently be used to produce ATP. Thus, the total yield from 1 glucose molecule (2 pyruvate molecules) is 6 NADH, 2 FADH2, and\xa02 ATP. For every pair of electrons transported to the electron transport chain by a molecule of NADH, between\xa02\xa0and\xa03 ATP\xa0are generated. For each pair of electrons transferred by FADH2, between 1 and\xa02 ATP\xa0are generated. | |
| 972. |
why are proteases generally released in inactive form |
| Answer» Proteases\xa0are\xa0released in inactive form\xa0because they are\xa0enzymes\xa0that are required only when there needs to be a balance or breaking down of the formed proteins in the body.\xa0Proteases are secreted in an inactive state because if they were active, then they could digest the cells in which they are stored. This would lead to tissue damage via the "digestion" of healthy tissue. | |

The leaf with ligule is called?? |
| Answer» A ligule (from Latin: ligula "strap", variant of lingula, from lingua "tongue")—is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges. A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae.\xa0The ligule is part of the leaf that is found at the junction of the blade and sheath of the leaf. It may take several forms, but it is commonly some form of translucent membrane or a fringe of hairs. The membranous ligule can be very short 1–2 mm (Kentucky bluegrass, Poa pratensis) to very long 10–20 mm (Johnson grass, Sorghum halepense), it can also be smooth on the edge or very ragged. Some grasses do not have a ligule, for example barnyardgrass (Echinochloa crus-galli). | |

Why dicot roots have fewer xylem bundles as compared to monocot laef |
| Answer» In\xa0dicot\xa0stems,\xa0vascular\xa0bundles are\xa0arranged\xa0in a ring toward the stem periphery. In\xa0monocot\xa0stems, the\xa0vascular\xa0bundles are randomly scattered throughout the ground\xa0tissue. Leaves include two\xa0different\xa0types of photosynthetic parenchyma cells (palisade and spongy).\xa0Monocot\xa0stems have most of their vascular bundles near the outside edge of the stem. ...\xa0Monocot roots, interestingly, have their vascular bundles arranged in a ring.\xa0Dicot roots\xa0have their\xa0xylem\xa0in the center of the\xa0root\xa0and phloem outside the\xa0xylem. A carrot is an example of a\xa0dicot root. | |

How does blood flow through the heart during different phases of cardic cycle |
| Answer» The heart is roughly triangular in shape. It has four compartments called chambers inside it. The upper two chambers of the heart are called atria and the lower two chambers are called ventricles. The atria receive blood from the two main veins. The left atrium is connected to the left ventricle through a valve V1 and the right atrium is connected to the right ventricle through another valve V2. These valves prevent the backflow of blood into atria when the ventricles contract to pump blood out of the heart to the rest of the body because when the ventricles contract, the valves V1 and V2 close automatically so that the blood may not go back into the atria. The job of heart is to pump blood around our body. All the atria and ventricles of the heart contract and relax at appropriate times and make the heart behave like a pump. A sheath of tissue called pericardium protects the muscular heart.Working of Human blood circulatory system takes place in the steps below:(i) When the muscles of all the four chambers are relaxed, the pulmonary vein brings the oxygenated blood from the lungs in the left atrium of the heart.(ii) When the left atrium contracts, the oxygenated blood is pushed into the left ventricle through valve V1.(iii) When the left ventricle contracts, the oxygenated blood enters the main artery called aorta from which it goes to the different body organs through small branches called arterioles and capillaries.(iv) The main artery carries the blood to all the organs of the body head, arms etc except the lungs. The oxygenated blood gives off oxygen, digested food and dissolved materials to the body cells. The carbon dioxide produced in the cells enters the blood. The deoxygenated blood enters main vein called vena cava which carried it to the right atrium of the heart.(v) When the right atrium contracts, the deoxygenated blood enters right ventricle through valve V2.(vi) When the right ventricle contracts, the deoxygenated blood enters the lungs through pulmonary artery and releases carbon dioxide and absorbs fresh oxygen from air. The blood becomes oxygenated again and is sent to the left atrium of heart by pulmonary vein for circulation in the body. This whole process is repeated continuously. | |
