Choice three makes the most sense for this question
Answer:
Humans would probably make themselves a different height. They would most likely make themselves prettier as well.
They would think this due to the fact that, if they were more attractive, they would be more socially accepted. This is because, sadly, people are very hateful. If they looked more like the image of what people like, then they would actually be "cared" for.
Answer:
B. The inducer combines with the repressor and inactivates the repressor.
Explanation:
A repressor is a negative regulatory protein. It inhibits transcription when bound to DNA. The inducer is a molecule that binds to a repressor protein. Binding of inducer to the repressor converts it into an inactive form. The inactive repressor is unable to prevent transcription. Therefore, when the inducer is added to the medium, it would bind to the repressor to inactivate it.
For example, the repressor protein of lac operon binds to the operator region and does not allow the expression of the lac operon. When lactose is present in the medium, few of the lactose molecules enter the bacterial cell and are converted into allolactose which in turn binds to the repressor protein. Binding of allolactose to repressor protein alters the shape of the repressor protein in such a way that it is no longer able to bind to the operator region. Here, allolactose is the inducer.
A chromosome is made up two chromatids that are joined in the centromere. Chromatids will separate during mitosis to create brand new chromosomes.
