Answer:
Essay on types of digestion
Explanation:
Digestion refers to the breakdown of large food molecules into small food molecules so that can be absorbed by the blood. There are two types of digestion i. e. mechanical digestion and chemical digestion. in mechanical digestion, the food is broken down into smaller parts physically with the help of teeth while on the other hand, in chemical digestion, food is broken down into small particles with the help of chemicals such as acids and enzymes. This chemical digestion is carried out in the stomach where different types of chemicals are present.
The answer is C. We can suppose that the Grey gene is "A" and Black gene is "a". So the gene of heterozygous grey fruit fly is "Aa", and the black-bodied fruit fly is "aa". After mating, the offspring can get only "a" from balck-bodied fruit fly and has equal opportunity to get a "A" or "a" from heterozygous grey fruit fly. If the gene of offspring is "Aa", it will be grey. If "aa", it will be black. So the proportion of being black is 0.5.
The answer is A as during anaerobic respiration, as there is no oxygen, glucose is converted into ethanol and lactic acid to produce some energy.
