Answer:
As a cell is formed during meiosis in prophase I, each chromosome matches up with its opposite chromosome that is the same size. These chromosomes are both maternal (from the mother) and paternal (from the father). Then, the bottoms of these chromosomes exchange genetic information by replacing the bottom of one of their strand.Genetic recombination
When a cell undergoes meiosis, it gets either its mother's or father's chromosome for each cell. The chances for each of these is completely random, so it produces genetic diversity instead of it all coming from one parent.

- Nucleic Acids. The nucleic acids are DNA and RNA, or deoxyribonucleic acid and ribonucleic acid, respectively.
-Proteins. Proteins are probably the most versatile of all the organic molecules, making up many structures and executing various functions within organisms.
-Carbohydrates. Carbohydrates comprise the largest number of organic molecules in organisms. Basically, carbohydrates are sugars; their origin can be traced to photosynthesis, the process by which organisms such as plants use sunlight to transform carbon dioxide and water into food.

The requirement of different nutrients, divide them into 2 categories.
Explanation:
On the basis of requirement of nutrients in our food, the chemicals are divided into 2 types - macronutrients, and macronutrients.
Nutrients are the molecules present in the food nourishes the living organisms. The macronutrients are needed in large quantities and they provide energy to the organism.
There are 3 major macronutrients present in every kind of food - proteins, fats, and carbohydrates.
On the other hand, micronutrients are required very less amount to the animals. But they are important for nourishment of the body, but their quantity is very less. Example of micronutrients are vitamins, minerals, manganese, iron, potassium, etc.
Therefore, it is told one should take balance diet to get all the nutrients.
