The substance is guided through a protein embedded in the membrane from high to low concentration since this not considered as active.
<span>the one that is not a source of genetic variation is : D. Asexual reproduction
In asexual reproduction, there is no fertilization process between male and female gender. Which mean the offspring that came from asexual reproduction would be exactly the same as its parent, without any chance of genetic variation</span>
Answer:
Because offspring with two parents will share half of each parent's DNA.
Explanation:
Sex cells contain half of the genetic information of an organism's regular cells. This is because a sexually-produced organism will be unique; it will share genetic information with both of its parents, rather than be identical to its bearer (like an asexual organism would be). When a sex cell meets another sex cell, their DNA will meet as well and change/adapt to suit the organism. If a sex cell had all the information needed to create an embyro, instead of half, which requires another cell's information to fill the DNA void.... well, it would just do it.
The answer is a “gene”
A gene is a functional segment of DNA that provides the genetic information necessary to build a protein. Each particular gene provides the code necessary to construct a particular protein.
