The correct answer is b. reproduction.
Reproduction is not essential to the survival of a single organism; however, to maintain a species, organisms must reproduce.
Hope this helps! :)
Answer: Prior to the process, the neuron is polarized; as the signal passes along the axon, the membrane depolarizes and repolarizes again, passing positive charges in and then back out.
Explanation:
The answer is B. The reason behind this is that El Niño decreases the rate of upwelling of water on the coast. Upwelling occurs when cold, nutrient-rich water “wells up” from the surface. If this process is disrupted manly due to El Niño, the movement of marine life is also affected. As a result, fish either migrate or die due to lesser nutrients coming up in the surface.
That answer would be no. because not all of them are the same.
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.
