Which characteristic distinguishes viruses from microorganisms such as bacteria and human cells? a. viruses are parasitic. selected: b. viruses can evolve. this answer is incorrect. c. viruses contain strands of dna. d. viruses can reproduce only inside a host cell.

d. Viruses can reproduce only inside a host cell.

Explanation:

Viruses are acellular organisms and although they do not have cells, they are extremely dependent on these structures, since they do not have their own metabolism and do not have any organelles. Viruses can only reproduce within a host cell other than fungi and bacteria.

By parasitizing a cell, they induce the production of viral genetic material and proteins, controlling cellular metabolism. Due to this characteristic, viruses are called obligatory intracellular parasites.

Because they lack metabolism outside a cell, many authors do not admit that they are considered living beings. Other researchers, on the other hand, consider them alive because they can duplicate and exhibit genetic variability. Another point that contributes to this last classification is the presence of molecules such as proteins, lipids and carbohydrates.

answer: a. a gene that causes a specific trait.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
