The use of retroviral therapies can increase the patient's risk of developing cancer because they may integrate recombinant DNA into the genome in ways that may misregulate the expression of genes. Therefore the correct option is D.
<h3>What is retroviral therapy? </h3>
Retroviral therapy is an HIV treatment where medicines are taken as prescribed by a healthcare professional. This treatment reduces the amount of HIV in an HIV-infected person.
HIV does not have a cure but antiretroviral therapy can reduce the risk of potential health issues caused by HIV.
This treatment can help to control the virus in an HIV-infected person within 6 months. The treatment for HIV cannot prevent the transmission of other sexually transmitted diseases.
Therefore the correct option is D.

Answer:
Mutations increase genetic variation and the potential for individuals to differ
Explanation:
Mutations can result in an organism having a new allele. When that organism produces offspring their offspring are most likely to inherit the allele created from the mutation which could potentially lead to genetic variation.
This movement from a high concentration area to a low concentration are is called Active transport.
<h3>Active Transport</h3>
Active transport by definition is a process that is characterized by the movement of molecules against a concentration gradient. Additionally, this process requires energy.
As in the question above, glucose molecules have to be moved across the gut lumen of higher glucose concentration to the intestinal cells of relatively low level of glucose.

Answer:
If T=tall and t=short, what will be the physical appearance of the offspring in the cross?
Explanation:
It looks like your question is incomplete, so I'll try to fill in the blanks.
The offspring will depend on the parents. Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).
Here are all the possible crosses:
TT X TT = 100% TT (all tall)
TT X Tt = 50% TT, 50% Tt (all tall)
TT X tt = 100% Tt (all tall)
Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)
tt X tt = 100% tt (short)
Note that if there is a T present in the genotype (TT or Tt), that individual will be tall. The only way to produce short offspring is for the both parents to have a copy of the short allele (t).
