Answer:
Modern birds are descended from a group of two-legged dinosaurs. Based on these life-giving characteristics, scientists have concluded that theropods were ancestral birds. Perhaps the bird evolved from dinosaurs by accepting animal's pattern.
Explanation:
The respected scientific consensus is that the birds are Teherod dinosaur groups that continued living during the Mesozoic era. The velociraptor has a skull simmilar as the coyote and the brain of an pigeon.
Of course, these are just theories. It is not proven that birds evolved from dinosaurs, but many characteristics are leading to this theory, especially after the discovery of the primitive bird Archeopterik in Germany.

Explanation:
First answer choice is not supported by the graph because the blue bar (protein) is very small in comparison to the others. The third choice only holds true for the “moderate” category. Finally, heart disease is not even mentioned. Hope it helps!
Answer:
Negative feedback occurs when a system's output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body's homeostasis.
Answer:
The correct answer is "negative".
Explanation:
At pH 2 the net charge of the R groups of all the amino acids that comprise the peptide in question would be positive. This happens because of the high content of protons in a solution of pH 2, a value that is below the isoelectric point of all the amino acids. Since the peptide would have a positive net charge, it would migrate to the negative terminal of the gel because opposite charges attract each other.
