Answer:
A change in pH can change the ionization of the side groups of basic and acidic amino acids of proteins., It is important to remember that these charges of are importance in stabilizing a protein secondary and tertiary structure and consequently affects its function. Changing these charges alters these interactions and disturbs protein loops such as beta-sheets and alpha-helices. This can change the structure of a proteins enzyme’s active site and cause it to fail to bind to a substrate or catalyze a reaction.

Blue jays have caterpillars and mice as their food. An increase in the blue jay population will cause a decrease in the caterpillar and mice population since more blue jays will eat caterpillars and mice. As time passes, the blue jays will have a problem finding food since the caterpillar and mice population has decreased, so the blue jay population will eventually lower as well.
Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
Im pretty sure the answer is d but not 100% sure
