Where the digestive glands are present Mention the role |
| Answer» Digestive glands: The secretions of the digestive glands help in the process of digestion. These glands include salivary glands, gastric glands, intestinal glands, liver and pancreas.a) Salivary glands secrete saliva along with enzymes. Ptyalin is the starch hydrolysing enzyme secreted by salivary glands in human beings. It is also called as salivary amylase.b) Gastric glands secrete HCL, pepsinogen, mucous. Gastric juice is a secretion of gastric glands located in the lining of the stomach. It is mainly made up of electrolytes, mucus, enzymes, hydrochloric acid, intrinsic factor etc.c) Intestinal glands are present in the inner lining of small intestine. These secrete various enzymes which aid in the process of digestion of all the components of food.d) Liver is the largest gland in our body. The liver secretes a yellowish green watery fluid called bile. It is temporarily stored in a sac called the gall bladder.e) Pancreas is the mixed gland. It acts as both endocrine and exocrine gland. The pancreas secretes the pancreatic juice that helps to digest carbohydrates, proteins and fats. | |

Any 5 uses of convex mirrors |
| Answer» 1. Convex mirrors are used inside buildings: Large hospitals, offices or stores sometimes make use of convex mirrors in order to let people see what is around a corner to avoid people running into each other and prevent minor/major collisions.2. Convex mirrors are used in vehicles: They are used as a rear view mirror in vehicles because the mirror can diverge a beam of light and makes a virtual image. And as the focal length and radius of curvature of the convex mirror are virtual the image is always produced up the right way and that too smaller in size than the actual size of the object. So the mirror is able to give a wide view of the field.3. Use in magnifying glass: Two convex mirrors are placed back to back in order to make a magnifying class.4. Convex mirrors use also used as street light reflectors because they are able to spread light over a bigger area.5. They are also put on corners of roads so that you can see any cars coming to avoid collisions.6. They are also used in telescopes. | |

Discribe perasitic and seprophiteic nutrition |
| Answer» Parasitic mode of nutrition: In parasitic mode of nutrition, plants depend on other live plants or animals for their nourishment. Such plants are called as parasites and the ones on which parasites depend are called as hosts.\xa0The insectivorous mode of nutrition is observed in plants like pitcher plant and the Venus fly trap. They purely depend on other insects and small animals for their nutrition.Cuscuta is a parasitic plant which develops special roots called haustoria. Haustoria penetrate deep into host plant tissues and just absorb the nutrients from them.Saprophytic mode of nutrition: The plants which exhibit saprotrophic mode of nutrition are called as saprotrophs. Saprotrophs are the plants that obtain their nutrition from dead and decaying organic matter. Saprotrophs secrete digestive juices onto dead and decaying matter to dissolve it and then absorb nutrients from it. | |
