Amacromolecul that contains carbon, hydrogen, oxygen, nitrogen which is used by the body for growth and repair

Protein.

Explanation:

Biomolecules may be defined as the organic molecules that are present in the living organisms. Four important types of biomolecule are carbohydrates, proteins, lipids and nucleic acids.

Proteins are the polymers of the amino acids. The proteins monomer consists of hydrogen, carbon, oxygen and nitrogen. Proteins are important for the living organisms all enzymes, antibodies and clotting factors are made up of proteins. The proteins are important for the repair and the growth of the body.

Thus, the answer is proteins.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.

c is the answer to this question. altitude affects the weather because air molecules evaporate.
