Answer:

mutations can be either beneficial or harmful depending on the environment

Explanation:

Mutations can be defined as genetic changes in the nucleotide sequence of the genome of one organism. Mutations are usually neutral, but they can also be deleterious and/or beneficial depending on the environment. For example, recessive mutations that cause sickle-cell anemia, which is a recessive genetic disease that affects homo-zygous individuals, have shown to be advantageous for heterozygous individuals living in regions where malaria is endemic. Beneficial mutations can be selected by natural selection, thereby increasing their frequency in the population.

Explain why glucose consumption must increase in hypoxic tissues to provide the same amount of ATP that could be produced from g
slega [8]

Answer: B. In hypoxic tissues, in contrast to normoxic tissues, ATP is additionally consumed to transform lactate to pyruvate

Explanation:

In hypoxic tissues such as new cancerous cells, the vascular system is still underdeveloped, thus oxygen supply is reduced. To meet energy need, additional glucose is needed to convert lactate (result of anaerobic glycolysis) to pyruvate which can then go into the TCA cycle to yield energy. This phenomenon is very common in muscle tissues during exercise.
