<u>Answer:</u>
The correct answer for this is: Microevolution.
<u>Explanation:</u>
The change of England's Biston betularia moth populations from light colored to dark colored is an example of 'Microevolution'.
Basically, the change that occurs over time in the allele frequencies within a group of species or population is known as microevolution.
The four processes due to which this change occurs include gene flow, selection (natural and artificial), mutation and genetic drift.
Active transport moves substances against the concentration gradient. is a major difference between facilitated diffusion and active transport
<u>Explanation:</u>
One of the comparisons is that both facilitated diffusion and active transport utilize proteins as their medians of moving their materials to and from the cell. Another relationship is the primary purpose of both facilitated diffusion and active transport is to drive material over the cell membrane.
One of the variations is that active transport demands energy, while facilitated diffusion does not require energy. The energy that active transport uses is ATP. The Major difference is that facilitated diffusion enables substances to accompany the concentration gradient either way, while active transport only has substances go one way, against their concentration gradient.
Answer:
The <u>biological species concept</u> is not very useful in defining plant species.
Explanation:
The biological species concept says that <em>species are population groups that, in a real or potential way, can reproduce and that </em><em>are reproductively isolated from other groups.</em>
<em>Individuals belonging to a species cannot reproduce with members of other species. </em>
This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.
Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.
Finally, this concept is not adequate in concern to hybridization zones, something to be expected considering evolutionary processes. This is why this concept has been less accepted by botanists, as some plant species hybridize with other species. For example, species Quercus grisea and Quercus gambelii have overlapping ranges in the southwestern United States. Hybrids showing variation in leaf shape and other traits have been found in many places in this area.
That would be Artificial Selection.
DNA is used for replication in cells, the replication is called Semi conservative. Tis is when two strand of DNA are used as a code for a new DNA molecule.
