Write about Clotting of blood in 50 words??????????????????????????? |
| Answer» Blood Clotting As the blood flow out from damaged blood vessel and comes in contact with external air,ruptured blood platelets of injured tissue release a substance called thromboplastin.It in the presence of Ca and few clotting factors converts prothrombin to thrombin.Prothrombin is a protein present in blood plasma.\xa0Thrombin then hydrolysis fibrinogen(large soluble protein present in blood plasma)The soluble fibrinogen is converted into insoluble fibrin by the action of thrombin. Fibrin forms needle like fibres.These fibres form a mesh work into which RBC become trapped and blood clot is formed(thick jelly which closes the ruptured blood vessel so that blood stop flowing) | |

Whai is holozoic |
|
Answer» Animals take in solid food and break it down it inside their own respective body.. For understanding take the example of amoeba T Holozoic nutrition can be defined as a method of nutrition which involves the ingestion of some complex organic substances that may be in the solid or the liquid state. Here, certain parts of some plants or some animals or the organism as a whole are ingested. In this type of nutrition, the complex food is transferred into a specialized digestive system where it is broken down into small pieces in order to be absorbed. The 5 crucial stages that holozoic nutrition can be broken down into include:\xa0ingestion, digestion, absorption, assimilation, and egestion. |

Explain the process of digestion and absorption of food in man? |
| Answer» \xa0The major organs or structures that coordinate digestion within the human body include the mouth, esophagus, stomach, small and large intestine, and liver.\xa0Mouth-\xa0The mouth\xa0is a specialized organ for receiving food and breaking up large organic masses. In the mouth, food is changed mechanically by biting and chewing.\xa0Food is moistened by saliva.\xa0The saliva contains an enzyme called\xa0amylase, which digests starch\xa0into\xa0maltose. During chewing, the tongue moves food about and manipulates it into a mass called a\xa0bolus. The bolus is pushed back into the pharynx\xa0and is forced through the opening to the esophagus.Esophagus-\xa0The bolus of food moves through the esophagus by peristalsisStomach - The\xa0stomach\xa0is an expandable pouch located high in the abdominal cavity. Layers of stomach muscle contract and churn the bolus of food with gastric juices to form a soupy liquid called chyme. The stomach stores food and prepares it for further digestion. In addition, the stomach plays a role in protein digestion. Gastric glands called\xa0chief cells\xa0secrete pepsinogen, which is converted to\xa0pepsin in the presence of hydrochloric acid.\xa0The pepsin then digests large proteins into smaller proteins called peptides. To protect the stomach lining from the acid stomach\xa0cells secretes mucus that lines the stomach cavity.Small intestine: The\xa0chyme enters from\xa0stomach to the small intestine. The three parts of small intestine are\xa0duodenum, jejunum and\xa0ileum.\xa0The inner surface of the small intestine contains numerous fingerlike projections called\xa0villi. Each villus has projections of cells called\xa0microvilli\xa0to increase the surface area.Most chemical digestion takes place in the duodenum. In this region, enzymes digest nutrients into simpler forms that can be absorbed. Intestinal enzymes are supplemented by enzymes from the pancreas. In addition, bile enters the small intestine from the gall bladder to assist in fat digestion.The enzymes functioning in carbohydrate digestion include amylase (for starch), maltase (for maltose), sucrase (for sucrose) and lactase (for lactose).For fats, the principal enzyme is lipase. Before this enzyme can act, the large globules of fat must be broken into smaller droplets by bile.Protein digestion is accomplished by several enzymes, including two pancreatic enzymes: trypsin and chymotrypsin. Peptides are broken into smaller peptides, and peptidases reduce the enzymes to amino acids.Nucleases digest nucleic acids into nucleotides in the small intestine also.The products of digestion enter cells of the villi, move across the cells, and enter blood vessels called capillaries. Diffusion accounts for the movement of many nutrients, but active transport is responsible for the movement of glucose and amino acids. The products of fat digestion pass as small droplets of fat into lacteals, which are branches of the lymphatic system.Substances that have not been digested or absorbed then pass into the large intestine.Large intestine -\xa0The large intestine\'s chief functions are to absorb water and to store, process, and eliminate the residue following digestion and absorption. The intestinal matter remaining after water has been reclaimed is known as\xa0feces.\xa0The feces are stored in the rectum and passed out through the **** to complete the digestion process. | |

How the rainbow form |
|
Answer» \tA rainbow is a natural spectrum of sunlight in the form of bows appearing in the sky when the sun shines on rain drops.\tIt is combined result of reflection, refraction and dispersion of sunlight from water droplets, in atmosphere.\tAlways it formed in the direction opposite to the sun.\tTo see a rainbow, the sun must behind us and the water droplets falls infront of us.\tWhen a sunlight enters into a spherical rain¬drop, it is refracted and dispersed. The different colours of light bent in different angles.\tWhen different colours of light fall on the back inner surface of drop, it (water drop) reflects (different colours of light) internally (total internal reflection).\tThe water drops again refracts the different colours, when it comes out from the raindrop.\tAfter leaving this different colours from the raindrop as rainbow, reach our eye. Thus, we see a rainbow. A rainbow is formed by the dispersion of sunlight by tiny water droplets present in the atmosphere. The water droplets act like small prisms. Th ey refract and disperse the light ray coming from the sun, and reflect internally and finally refract it again when it comes out of the rain drop. That\'s how a rainbow consisting of seven colours is formed. |
