Transposable elements and short tandem repeats are different because short tandem repeats make up only a small percentage of a given genome while transposable elements often make up larger parts of a genome. So the correct option is C.
<h3>
What are transposable elements? </h3>
Transposable elements or transposons are a class of genetic elements. They can “jump” from one location to another, in a genome.
Even though they are called “jumping genes,” they have an integrated site in a genome and are maintained there. Also, most of them are eventually inactivated and can not move any longer.
Whereas Short tandem repeats or STRs are short repeats of DNA. They are also known as microsatellites or simple sequence repeats. They have a repetitive unit of 1-6 bp and form a series of 100 nucleotide lengths.
Therefore the correct option C.

The answer would be C. Energy is used through the food chain so energy always decreases. Population size would commonly decrease according to the pyramid of food chain but since there's no answer for that, C would be the most suitable
<span>The importance of the G0 phase is that during cell division when the cell get a signal that there are enough of cells (not more required) or there is a mutation in the cell that need to be fixed before they differentiate fully or the cell during its division gets damage then it is signalled to rest, and it is this phase that cell leave the cycle and quit dividing. It could be temporary resting period (so when cell again required, or damaged got fixed) then the cells will again join the cycle and continue to divide again or it can also be permanent for example neurons, which are resting in G0 phase and never divides again.</span>
