What is true about the structure or function of the plasma membrane? The double layer prevents anything from entering the cell.

The processes of endocytosis and exocytosis occur here.

It is made entirely of integral proteins.

Hydrophilic molecules attract the water the cell requires.

where is the scientific experiment?

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).

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.
