When growth in a child is impaired by a deficiency of endogenous growth hormone, somatropin may be prescribed. when in the period of growth and development must somatropin (humatrope) be administered to children?

Before epiphyses closure

Explanation:

Somatropin is also known as the growth factor or Human Growth Hormone. The human Growth Hormone is involved in the growth of a cell, in the regeneration of cell and cell reproduction.

Epiphyses can be described as expanded, long, round ends of bones which are present in animals and humans. It helps in the growth of bone. Hence, the somatropin should be given to the child before the closure of epiphyses.

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.
