Compare and contrast viruses and cells. Explain a minimum of 4 similarities and/or differences.

1 answer:

4 0

The first difference is the size, cells are sized in micrometer (visible at optic microscope) and viruses in nanometer (electronic microscope).

Cells have both DNA and RNA, virus have only one genetic material (DNA or RNA).

Cells have always a membrane, not all the viruses have a membrane, but all of them have capsids in different forms.

Viruses cannot live on their own, they have to parasite a cell to proliferate. Cells can live by themselves and proliferate by scissiparity (divisions).

Cells have ribosomes to translate their RNA. viruses don't (they use the infected cells' ribosomes).

You perform a study in which humans can choose to eat proteins, lipids/carbohydrates, and/or vitamins/minerals. Due to your adva

Advocard [28]

Answer:

It depends...

Explanation:

Group 1 is trying to obtain energy, so as we know that lipids and carbohydrates are the basic source of energy because of their storage properties and generation of ATP during glycolysis and lipid metabolism in our body.

Group 2 is trying to obtain nutrients so to rebuild their molecules and body cells they must take enough quantities of vitamins/minerals for that. Proteins are also crucial to for rebuilding lipo-proteins in cell wall of cell amke them crucial for them. They also play an important role in muscle cell repair and replacement due to their primary composition of actin and myosin filaments.
