According to the image, the fish underwent sympatric speciation. The new species of fish had mating seasons that were different from that of the original fish. Because of the differences in mating seasons, the fish underwent reproductive isolation. This mode of isolation would be temporal.
Sympatric speciation happens within a population of an organism that gets isolated reproductively due to differences in their mating periods. This time dependent isolation is called temporal isolation. Example, a fish population can split into two if some of the fishes start mating early in the spring while the rest mate late in the autumn. The spring-mating population will not become compatible to mate with the late-autumn-mating population.
Protein, Golgi Apparatus
Reasoning - Since the ribosomes is creating the proteins it is the. Transported/Packaged into the Golgi apparatus where it is stored :)
The vibrations of the music coming from the speaker makes the sand move.
Sex cells only contain one chromosome from each pair. When an egg cell and spermcell join together, the fertilised egg cell contains 23 pairs of chromosomes..
I am 99% sure that is the answer.
Answer:
c) Moderately repetitive DNA contains retro elements, such as the Alu sequence.
Explanation:
The genetic material (DNA) has been proven to contain segments or sequences that are non-coding regions i.e. do not encode proteins. These non-coding sequences can either be repeated in the genome (repetitive) or not (non-repititive). The repetitive DNA sequences can consist of short sequences that repeat themselves enormous amount of times in the genome. This repetitive DNA sequence is said to be HIGHLY repetitive.
Another one can contain long nucleotide sequences scattered in the genome. They do not repeat as often as the highly repetitive sequences. They contain retro elements like Alu sequences and transposons. These sequence is said to be MODERATELY repetitive.
The non-repititive sequences are the part of the DNA that encodes a protein. They are called unique sequences because they occur in only one or few copies in the genome.
