Which of the following is NOT true of viruses?

Viruses must always have their own metabolism

Viruses must always be parasitic and must always have their own metabolism
c
Viruses must always be parasitic

Viruses must always contain nucleic acids (RNA or DNA).

None of the Choices

Viruses must always have a capsid

A and B

Explanation:

Viruses doesn't have their own metabolic activities because if they did they should be able to live on their own and not be parasitic .

But option be seems confusing however since both statements cannot be true hence the overall statements negate it as wrong.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
