Answer:
When comparing homologous structures, we are comparing the anatomy of one part of an organism to another and finding it to be structurally similar but functionally may be different. Let’s compare a couple of tetrapods, specifically a human arm and a cat arm.
Both the human arm and the cat arm have a single bone in the upper arm, which we call the humerus, followed by two bones in the forearm–the radius on the more medial side and the ulna on the more lateral side. Both arms also have a common wrist structure followed by a grouping of metacarpals and phalanges. All of these structures are similar; however, these structures do not have the same function. Cats are quadrupeds that use their arms for walking and maybe a little climbing and hunting for outdoor cats. Humans, on the other hand, use their arms and hands for gross motor movement like grabbing, hugging, and lifting, as well as fine motor movement like using tools or even communicating.
A whale flipper and a bat wing are also homologous structures in the same sense as a human arm and cat arm with a humerus, radius and ulna, and so on. But the whale’s “arm” is actually a flipper that it uses to swim while the bat uses its wing to fly.
Answer:
the answer is
a. changes it to a form that affects the target cell behavior
Explanation:
Purines bases are ADENINE(A) and GUANINE(G), and pirimidines bases are CITOSINE(C) and TIMINE(T).
In DNA, with ADENINE complementary base is TIMINE, and with GUANINE complementary base is CITOSINE.
The premises that reinforce the thesis "the human drift", statement are A) 1, 2, and 3.
- The objective of a thesis statement, which often consists of one or two phrases, is to lead the author so that he or she doesn't lose focus while also educating the reader about the author's viewpoint and the topic of what will be read by the man.
- The thesis statement in the "The Human Drift" passage by Jack London reveals that the topic under discussion will be how humans have improved upon and become more proficient at killing.
- The thesis statement should be supported and reinforced by the premises. In this instance, the thesis statement will be well supported by any premise that demonstrates the development of man's killing techniques and the diversity of his prey.
- Those are the exact things that sentences 1, 2, and 3 do. They discuss how man kills to maintain his dominance over other species, how killing tools were created perhaps too early in man's history, and how man has improved to the point where he can kill germs.

Albert Einstein: Devout in his youth, Einstein's knowledge and appreciation of science led him to reject the Bible's miracle-producing God. I do indeed hope this helps.
