For each of the following hypothetical situations, explain what would possibly be going on in the cell to lead to the situation. be sure to include information on the organelle(s) involved and provide support your statements.

-the number of proteins produced dramatically decreases
-the cell membrane can no longer be repaired
-the vacuole in a plant cell shrinks to 30% of its original size
-vesicles are no longer produced in the cell
-proteins are not chemically labeled

You hate the smell of mercaptoethanol. since there are no disulfide bonds in intracellular proteins, you have convinced yourself that it is not necessary to treat a cytoplasmic homogenate with mercaptoethanol prior to sds-page. you heat a sample of your homogenate in sds and subject it to electrophoresis. much to your surprise, your gel looks horrible; it is an ugly smear! you show your results to your friend who is a chemistry major, and she suggests that you treat your sample with n-ethylmaleimide (nem), which reacts with free sulfhydryls. you run another sample of your cytoplasmic homogenate after treatment with nem and sds. now the gel looks perfect! if intracellular proteins don't have disulfide bonds (and they don't) why didn't your original scheme work? and how does treatment with nem correct the problem?

Advances in technology have enabled scientists and researchers to better study the evolutionary relationships between species

All individuals have two alleles for a given trait. according to mendel's these alleles are passed down one each from both mother and father.
