Answer» U dont hav to write this much for 3 mark Central nervous system: It includes the brain and the spinal cord.\xa0It receives information from the body and sends out instructions to particular organs.\xa0• The forebrain is the main thinking part of the brain. It consists of the cerebrum and diencephalon. The cerebrum is the seat of memory and intelligence, and of sensory centres like hearing, smell and sight. The diencephalon is the seat for pressure and pain.• The midbrain connects the forebrain to the hindbrain and controls the reflexes for sight and hearing.• The hindbrain consists of the cerebellum, pons and medulla. The cerebellum coordinates muscular activities and maintains balance and posture. The medulla controls involuntary activities like blood pressure and beating of the heart.• The spinal cord extends from the medulla of the brain through the whole length of the vertebral column and is protected by the vertebral column or backbone. |

exlain digestion system |
| Answer» Entire information about digestive system is given. You can mould it as per your requirement.Digestion: Digestion is the process by which food is broken down into simple absorbable substances. Digestion of food takes place in the digestive system. Digestive system is made up of alimentary canal and associated glands. Parts of alimentary canal: The mouth, oesophagus, stomach, small intestine and large intestine form the alimentary canal. It is also known as the digestive tract.Mouth is guarded by upper lip and lower lip. The process of taking in food through mouth is called as ingestion.Buccal cavity is the inner region of the mouth. It encloses teeth and tongue.Teeth are of different types namely, incisors, canines, premolars and molars.Incisors are used for biting food.Canines are sharp and pointed and are used to pierce or tear food.Premolars and molars are the principal grinders helping to chew and grind the food.Tongue is a muscular organ attached to the floor of the buccal cavity at the back. It helps in mixing of food with saliva and swallowing it. It also helps in tasting different types of food with the help of taste buds present on it. The buccal cavity leads into pharynx.Pharynx is at the back of buccal cavity. The pharynx is the common channel for food and air. When you swallow food, a flap-like valve called the epiglottis closes the windpipe. It prevents the entry of food particles into respiratory tract.Oesophagus also called as food pipe helps in conveying the food from buccal cavity to stomach. The oesophagus is also known as the gullet. It is about 25 centimetres long. Food inside the oesophagus reaches the stomach by peristalsis movements.Stomach is the widest part of the alimentary canal. It is a J-shaped muscular organ with stomach occurs with the help of digestive juice. Digestive juice comprises of hydrochloric acid, mucous and some enzymes.Small intestine is made up of three regions namely duodenum, jejunum and ileum. Partially digested food called the chyme from the stomach is received by the duodenum. Duodenum also receives bile form the liver, enzymes from pancreas and secretes some enzymes on its own. All these substances bring about digestion of food in the intestine. The inner walls of the small intestine have millions of small finger like projections called the villi. Villi increase the surface area for digestion as well as absorption of digested food by eight times.Large intestine comprises of colon and rectum. Undigested food is sent into large intestine. Water from the food is reabsorbed to a great extent in the large intestine. Undigested waste is stored in the rectum for defecation.**** is the opening of the alimentary canal to the exterior. This helps in the elimination of faeces by the process of egestion.Associated glands: These glands include salivary glands, gastric glands, intestinal glands, liver and pancreas.Salivary glands are present inside the buccal cavity. They secrete saliva. This saliva plays an important role in breaking down complex components like starch into simple sugars.Gastric glands present inside the stomach secrete gastric juice which helps in the digestion of food.Intestinal glands secrete various enzymes which aid in the process of digestion of food.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. Bile plays an important role in the digestion of fats. Bile is sent into duodenum through a narrow tube-like structure called the bile duct. Bile breaks the larger fat molecules into tiny droplets, thereby increasing their surface area, which helps in the digestion of fats easily.Pancreas is the mixed gland. It acts as a both endocrine and exocrine gland. The pancreas secretes the pancreatic juice that helps to digest carbohydrates, proteins and fats. The pancreatic juice converts carbohydrates into simple sugars and glucose, proteins into amino acids, and the lipids into fatty acids and glycerol. | |

What is difference between light reaction and dark reaction? |
| Answer» \tLight Reaction (light dependent reaction)Dark Reaction (light independent reaction)It occurs in thylakoid membranes of chloroplasts in a leaf.It occurs in the stroma of the living chloroplast.Light energy is absorbed by photosystems PS-I and PS-IICarbon dioxide present in the atmosphere is absorbed.Cyclic and non-cyclic photophosphorylation occur in the cellsC3 pathway is observed in green plants. In desert plants, we can observe c4 pathway.End products are ATP and NADP.H2.End products of light reaction are used up to synthesise sugar.Oxygen is released as a by-product of the photolysis if water.Main product is sugar in the form of glucose\t | |

How do guard cell control the opening and closing stomata? |
|
Answer» The\xa0opening and closing of stomata are controlled by the guard cells. When water flows into the guard cells, they swell up and the curved surface causes the stomata to open. When the guard cells lose water, they shrink and become flaccid and straight thus closing the stomata. When the required amount of water in reach the left then guard cell automatically close & when there is need for air they automatically open |

Give an example of a chemical equation |
| Answer» Representation of chemical reaction using symbols of substances is called chemical equation.Example: A + B → C + DIn this equation, A and B are called reactants and C and D are called the products. Arrow shows the direction of chemical reaction. Condition, if any, is written generally above the arrow.Example: When hydrogen reacts with oxygen, it gives water. This reaction can be represented by following chemical equation.Hydrogen + Oxygen ⇨ Water2H2 + O2 →2H2O | |

Why should we keep butter in fridge |
| Answer» Here are a few reasons :\tAt higher temperature butter will lose texture ( become soft and semi-liquid), accelerating the lose of quality and spoilage.\tAt higher temperature, microbes present in the water portion of butter ( specially in unsalted butter), can also metabolize proteins and sugar to produce compounds that have undesirable flavor.\tAt refrigeration temperature, these changes occur at a considerably slower rates and butter maintains its sweet pleasant flavor for fairly long time. | |

What is olfactory? |
|
Answer» OLFACTORY is a receptor of nose sense organ. The substance which changes their odour with an acid or base are called olfactory indicators. Olfactory indicators are those indicators that help to identify whether the given solution is acidic or basic by changing their smell instead of colour as other indicators do.Onion: Paste or juice of onion loses its smell when added with base. It does not change its smell with acid.Vanilla:\xa0The smell of vanilla vanishes with base, but it’s smell does not vanishes with an acid. Olfactory is a sense which is related to smell. |
