Which structure has the least effect on the ability of a virus to infect and replicate in a host cell? envelope capsid dna ribosome

Correct B). Capsid

The capsid is found in viruses, which contain the viral genome packaged in a protein coat known as the capsid. It is considered a shell covering of the virus, which is made of a protein called protomers.

It is surrounded by the lipid layer that holds the viral protein, which helps the virus to bind with the host cell.

So, we can say that capsid has the least effect on the ability of the virus to infect a host.

abiotic: living organisms within an ecosystem

biotic: non-living organisms within an ecosystem

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
