How the minerals are absorbed by the plants? |
| Answer» In plants and animals,\xa0mineral absorption, also called\xa0mineral\xa0uptake is the way in which\xa0minerals\xa0enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for\xa0mineral\xa0uptake is usually through the roots. Some\xa0mineral\xa0ions diffuse in-between the cells.\xa0In order to\xa0absorb\xa0any\xa0minerals\xa0from the soil, it should be dissolved in the water.\xa0Plants absorb\xa0most of the\xa0minerals\xa0through the roots. ... In roots, the\xa0mineral absorption\xa0usually takes place through the meristematic region of the root tip. | |

Flow chart showing the passeage of air to lungs |
| Answer» In human beings, air is taken into the body through the nostrils, is filtered by fine hairs that line the passage. When air passes through the nasal passage, the dust particles and other impurities present in it are trapped by nasal hair and mucus so that clean air goes into the lungs. From here, the air passes through the throat and into the lungs. Trachea does not collapse even when there is no air in it because it is supported by rings of soft bones called cartilage.Within the lungs, the passage divides into smaller and smaller tubes which finally terminate in balloon-like structures which are called alveoli. The alveoli provide a surface where the exchange of gases can take place. The walls of the alveoli contain an extensive network of blood-vessels. When we breathe in, the ribs are lift up and the diaphragm flattens which increases the size of the chest cavity. Because of this, air is sucked into the lungs and fills the expanded alveoli. The blood brings carbon dioxide from the rest of the body for release into the alveoli, and the oxygen in the alveolar air is taken up by blood in the alveolar blood vessels to be transported to all the cells in the body. During the breathing cycle, when air is taken in and let out, the lungs always contain a residual volume of air so that there is sufficient time for oxygen to be absorbed and for the carbon dioxide to be released. | |

What is seed dormancy |
| Answer» Seed dormancy\xa0is defined as a state in which\xa0seeds\xa0are prevented from germinating even under environmental conditions normally favorable for germination. These conditions are a complex combination of water, light, temperature, gasses, mechanical restrictions,\xa0seed\xa0coats, and hormone structures.\xa0Seed dormancy\xa0allows seeds to overcome periods that are unfavourable for seedling established and is therefore\xa0important\xa0for plant ecology and agriculture. Several processes are known to be involved in the induction of\xa0dormancy\xa0and in the switch from the\xa0dormant\xa0to the germinating state. | |

Why are element carbon, hydrogen, oxygen and nitrogen called structural elements |
| Answer» Carbon has an exceptional ability to bind with a wide variety of other elements. Carbon atoms can form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen. Carbon atoms can also form stable bonds with other carbon atoms. In fact, a carbon atom may form single, double, or even triple bonds with other carbon atoms. This allows carbon atoms to form a tremendous variety of very large and complex molecules. | |

Inhibition of succinic dehydrogenase by malonate is said to be competitive why? |
| Answer» In the presence of\xa0malonate, increase the concentration of the normal substrate and see\xa0whether\xa0the rate of reaction increases. If it does,\xa0malonate is a competitive inhibitor. Malonate is a competitive inhibitor of the enzyme succinate dehydrogenase: malonate binds to the active site of the enzyme without reacting, and so competes with succinate, the usual substrate of the enzyme.en water sample at certain temperature over a specific time period. | |
| 5312. |
What is homeostatis?Average time taken by bacteria to divide |
| Answer» Homeostasis is a property of a human biological system where the self-regulating process tends to maintain the balance for the survival. The regulation takes place in a defined internal environment. For example- the presence of glucose in blood plasma, regulation of body temperature, extracellular fluids of an animal despite changes- what the animal has eaten or what it is doing. Every variable is controlled by homeostasis together to maintain life.In simple terms, it could be referred as a balance in a system to maintain a stable internal environment for the survival of the animal. If the homeostasis regulates successfully, life continues or if unsuccessful, death or disaster occurs. | |

BOD???? |
| Answer» BOD stands for Biochemical Oxygen Demand.It is the amount of dissolved oxygen required by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.\xa0Biochemical oxygen demand\xa0(BOD) represents the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic (oxygen is present) conditions at a specified temperature. | |

How diffusion differ from osmosis |
|
Answer» Osmosis is the transport of water or any other solvent molecules from a region of lower concentration to a region of higer concentration through a semipermeable membrane. Diffusion is the transport of material from a region of higher concentration or electrochemical potential or free energy or diffusion pressure due to tendency of their molecules to spread uniformly by their random movement due to their kinetic energy. ? Osmosis is special type of diffusion in which only water moves from region of higher concentration you a region of lower concentration through a semi permeable membrane |

Explain the process of digestion in human beings. |
| Answer» Digestion of food in human beings begins in the mouth. The mouth cavity contains teeth, tongue and salivary glands. The teeth cut the food into small pieces, chew and grind it. This is called physical digestion. Salivary glands produce saliva which mixes with the food. This involves chemical digestion of food. The saliva contains an enzyme called salivary amylase which digests the starch and converts it into maltose sugar. Mouth opens into a small funnel shaped area called pharynx which leads to a long tube called oesophagus. It carries the food down into the stomach. The wall of oesophagus is muscular. When the slightly digested food enters the food pipe, the walls of the oesophagus starts contraction and expansion movements called peristaltic movements which push the food into the stomach. Digestion does not take place in the oesophagus.The glands present on the walls of the stomach secrete gastric juice that contains hydrochloric acid, the enzyme pepsin and mucus. A small amount of gastric lipase is also present that breaks down the fats present in the food. Gastric juice is acidic due to the presence of HCl which is necessary for the pepsin to become active and converts the proteins into peptones. The mucus protects the stomach walls from HCl. From the stomach, the partially digested food goes into the small intestine through sphincter muscle. Small intestine is divided into two parts: Duodenum and Ileum.Duodenum receives the secretions of two glands, liver and pancreas through a common duct. Liver secretes bile which is alkaline and contains salts to emulsify the fats (or lipids). The bile secreted by the liver is stored in the gall bladder. Pancreas secretes pancreatic juice which contains trypsin, lipase and pancreatic amylase. Trypsin digests the proteins, lipase emulsifies the fats and pancreatic amylase breaks down the starch. Thus, small intestine is the site of complete digestion of carbohydrates, proteins and fats. The walls of ileum secrete succus entericus which completes the digestion process. | |
