They both do not produce there own food they consume it in the matter
Such organisms are called carnivores
The answer is A, cells, as viruses infiltrate cells, make copies of themselves in them, and then lyse the cell and spread.
The correct answer is; "Assembling molecules in either hydroxyl or carboxyl functional groups"
Polymers are formed from monomers either by condensation or by addition of monomers.
A polymer is formed by the joining of one or more monomers. This can happen in either of the following ways;
Condensation polymerization involves the loss of a small molecule. When the molecule that is lost is water, we can call it dehydration. Loss of molecules does not occur in addition polymerization.
The two monomer molecules that join to yield the polymer by dehydration must have H and OH moieties in suitable positions for dehydration to occur. A typical example is assembling molecules in either hydroxyl or carboxyl functional groups.
