Answer:
5.Small intestine
The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins. Your liver produces bile that helps you digest fats and certain vitamins.
6.Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing. ... It's important to chew your food as much as possible, as taking longer to chew gives the enzymes in saliva time to begin the process of breaking down carbohydrates, a very important part of digestion.
7.Carbon dioxide, water, chlorophyll pigment, and sunlight are the necessary conditions required for autotrophic nutrition. Carbohydrates (food) and O2 are the by-products of photosynthesis.
8.Aerobic respiration takes place in presence of oxygen; whereas anaerobic respiration takes place in absence of oxygen. Carbon dioxide and water are the end products of aerobic respiration, while alcohol is the end product of anaerobic respiration. Aerobic respiration releases more energy than anaerobic respiration.It can be found only in the cytoplasm.
9.The alveoli are thin-walled and richly supplied with a network of blood vessels to facilitate the exchange of gases between blood and the air-filled in alveoli. ... They have a balloon-like structure that provides maximum surface area for exchange of gases.
