I would go with D as it is closest to correct. Every part of the surface of the Earth is a tectonic plate though. The plates vary in thickness, but all of the surface of the Earth is made up of tectonic plates, including the parts under the ocean. Technically, the Earth's landmass does not rest on the tectonic plates, it IS the tectonic plates, but it is the closest to correct here in my opinion.
Answer:
Somatic hypermutation is a process in which point mutations build up in the antibody V-regions of both the heavy and light chains.
This process occurs at rates that are about 106-fold higher than the background mutation rates observed in other genes.
It allows B cells to mutate the genes that they use to produce antibodies. This then ensures the B cells to produce antibodies that are better able to bind to bacteria, viruses and other infections.
<span>When cells divide uncontrollably, then there is a huge number of them and they take up most of the space in the body. Thus, lumps start to appear on and in a person's body, on organs and skin, and these lumps often represent cancer. So, uncontrollable division of cells can lead to cancer. Hope this helps. Let me know if you need additional help!</span>
Competition factor are the species of birds responding to in the environment. Thus, the correct option is B.
<h3>
What is competition?</h3>
If numerous bird species eat on the same tree species, there will be fierce competition for food. As a result of the competition, each species will seek out a certain portion of the plant to feed on, most likely the part of the plant where it will be easiest to outcompete the competitors for food.
As a result, we may deduce that the right response is "They have evolved to diverse niches as a result of competition."
