Answer: Glycolysis
Explanation:
Glycolysis is an universal process which takes place in all the organism from bacteria to humans. It can occur whether oxygen is present or not. It is the first step of cellular respiration that takes place in cytosol.
During glycolysis, breakdown of the glucose into pyruvate occurs with the formation of two energy molecules of ATP and two NADH molecules.
Thus, the correct answer is option (A).
Answer:
I'm pretty sure the answer is D.) Less Dense
Explanation:

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.
