Ribosome

Explanation:

Viruses are defined as small, infectious biological agent that grow and reproduce inside the living hosts. Viruses are considered as non-cellular, made up of only protein and genetic material. The genetic material of viruses may either DNA or RNA.

As viruses are non-cellular structures, they do not possess any cellular organelles, such as ribosomes.

Thus, the correct answer is option). ribosomes.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
