What happens if cell cycle regulators don’t function properly

An organism may end up with too few or too many cells.

Explanation:

Cell cycle regulators are molecules that allow the cell cycle to be completed when the body really needs it and when all the conditions necessary for the cell cycle to happen are available. Through regulators, the body avoids energy waste, overproduction of new cells, as well as promotes the creation of new cells whenever necessary.

If these regulators fail, the organism will go into cellular imbalance because it will have nothing to stop a cell from multiplying more than necessary. In addition, if regulators fail the human body may have fewer cells than needed.

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.
