Endocytosis is the active transport of molecules into a cell. in a cell extends its membrane around large particles to ingest them. is similar in that the membrane extends around particles, but these are much smaller particles dissolved in fluid; thus the process is analogous to "drinking." involves specific membrane proteins that bind molecules such as hormones or carrier proteins and brings the specific membrane protein and the bound molecule into the cell.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.

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.
