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.

I think your answer is C but i’m not sure
Answer:
True
Explanation:
In Retrovirus such as HIV, when the virus enters the host's cell it releases enzyme reverse Transcriptase which generates a complementary DNA(cDNA) by the process called Reverse transcription.
By this process the positive single stranded RNA genome is liberated into a cDNA molecule.
Since the process of reverse transcription is prone to errors, it can cause mutation that lead to drug resistance or enable the virus evade the body's immune system.
