There are two main reasons why cells divide rather than continuing to grow larger and larger. One of the main reason is that the larger cell become more demanding, therefore the large cell will increase load on the machinery of the cell such as DNA. The other reason is that if the cell grow too large it will be difficult for the cell to move for nutrients and discard the waste across the cell membrane. Also the surface area for each cell will also be reduced, which is required for active functionality of a cell.
The correct answer is option B. Carbohydrates.
The Starch and the glycogen are the molecules, which belong to the carbohydrates. The carbohydrates are the sugar molecules or polymers of sugars. The general formula of the carbohydrate is
, the ratio of the carbon:hydrogen:oxygen is 1:2:1. The starch and the glycogen both are the polymers of the glucose the formula of the glucose is 
, hence, the the ratio of the carbon:hydrogen:oxygen in glucose is 1:2:1, hence, starch and the glycogen are carbohydrates.
Lipids is comprised of fats, oils, waxes as well as some hormone and molecules, they are different than the carbohydrates. Nucleic acids are the polymer of nucleotide consisting of sugar, phosphate group and nitrogenous base. The proteins are the the polymer of amino acids, not sugars.
The answer would be, "C".
Hey there!
El Nino typically involves waters with a warmer than usual surface temperature, a flatter thermocline (cooler water moves to the surface), and weaker trade winds. As for La Nina, think of it as the opposite of El Nino. There will be stronger trade winds, and cooler surface water temperatures.
Hope this helps!
