D for sure. That seems perfectly christian-minecraft server-y of a school to put that as an option, it must be right.
Vidence of common descent<span> of </span>living organisms<span> has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating the </span>common descent<span> of all </span>life on Earth<span> developing from a </span>last universal ancestor<span>. This evidence constructs the theoretical framework on which evolutionary theory rests, demonstrates that </span>evolution<span> does occur, and is able to show the natural processes that led to the emergence of Earth's </span>biodiversity<span>. Additionally, this evidence supports the </span>modern evolutionary synthesis<span>—the current </span>scientific theory<span> that explains how and why life changes over time. Evolutionary biologists document evidence of common descent by developing testable predictions, testing hypotheses, and constructing theories that illustrate and describe its causes.

Answer:
BbxBb.
Explanation:
If Bb gene is crossed with Bb, the offspring is produced with normal hearing because both the genes are recessive in which the deafness gene hide and the hearing gene is dominant so the offspring can hear sounds clearly. The dominant A gene is responsible for deafness and we can see the offspring BbxBb in which no dominant gene is present. The other three offspring are deaf because of the presence of dominant A gene in their genetic makeup.
The natural selection among peppered moths of Manchester, England can be mainly attributed to to the abruptly increasing levels of Air Pollution in England as a result of thriving Industrial Revolution In the U.K.
Soot from power producing factories, etc resulted in complete eradication of lichens in the flora of the surrounding region.
The frequency of the newly evolved peppered moth increased as the dark colour was beneficial in a polluted environment like in Manchester.
