<span>Methyl groups
</span>DNA<span> methylation is a process by which </span>methyl groups<span> are added to the </span>DNA<span> molecule. Methylation can change the activity of a </span>DNA<span> segment without changing the sequence.</span>
<span>The endoplasmic reticulum is responsible and takes part in lipid-processing and phospholipid manufacture functions of the cell. It is an interconnected sack of tube like walls and cells that make up a portion of the cell. This cell type occurs in most eukaryiotic types of cells.</span>
Answer:
d. the groups will probably diverge genetically, and speciation may occur
Explanation:
The geographical isolation of two populations of a species for a longer time period leads to allopatric speciation. During the process, the isolated populations accumulate genetic variations to become adapted to the prevailing conditions of the habitat.
Accumulation of genetic variations leads to reproductive isolation between the population. After several generations, the individuals of the two isolated populations are unable to interbreed due to genetic variations. Now, these two populations are said to belong to two different species. The isolated lizard populations would also accumulate genetic variations resulting in allopatric speciation.
Answer: The shoot grows up towards the sunlight is Positive Phototropism
The root grows down the soil is Positively Geotropism / positive gravitropism.
happy to help again :)
Answer:
my guess would be D
Explanation:
It could be C too, but I think D is a better answer
