The first one: A mutation may cause a change that codes for the same amino acid. It is not possible (or likely) that the transcription will skip over the mutation. Mutations, especially large frameshifts, are important. It does not matter how much proteins are replicated. A mutation in the DNA sequence will affect the mRNA.
Answer:
Regulation of intake is governed by thirst receptors that pick up signals of dehydration and return the body to a rehydrated state.
Explanation:
The state of hydration in someone's body is given by the plasma osmolarity values (the ratio of solutes to water in blood plasma). After regular activities that involve the loss of water, such as urination and sweating, happen, the blood begins to concentrate and the osmoreceptors located in the hypothalamus are triggered to generate a response that leads to water intake.
Answer:

Explanation:
A) First of all, it must be considered that HIV has a RNA genome.
The reverse transcriptase is a viral enzyme able to convert a RNA molecule (in this case the RNA would be the viral genome) to DNA. This process is important for two reasons:
* The DNA molecule is more stable than RNA --> Therefore, there is a higher likely that the molecule wouldn't be degradated by the host.
* The viral genome made of DNA will be integrated into the host genome --> To do so, it requires to be DNA instead of RNA
B) The inibitor is able to target the Reverse Transcriptase --> So, the likehood of converting RNA to DNA is lower. In this case, the single RNA molecule is less stable than the DNA and the host can degradate it more easily.
C) In general, the viral will not survive the treatment and, hence, the patient will not suffer from the viral infection
