natural selection and common descent are the 2 ideas Darwin used to explain evolution
Protiens are very important and they are regarded beneficial
The protiens and peptides differ in their size protiens are relatively small
There are soi many difference among both because
<span>Several amino acid sequences are possible for proteins and peptides
</span>As there are 20 amino acids and different folding structure
so correct option is A
hope it helps
C.) 45 AND 75............
Populations of organisms that have sigmoid growth curves
limited by the carrying capacity are called K-selected.
Species are divided into two selected species, R-selected
species and K-selected species. K-selected
species are <span>also called K-strategist. These are the species whose populations vary at or near the <span>carrying capacity <span>(K) of the </span></span>environment<span> in which they live.</span></span>
Messenger RNA (mRNA)
<span>Messenger RNA (mRNA) is known
to be molecules that carries codes (DNA) in the nucleus to the cytoplasm the
sites of protein synthesis. Thus, it is the RNA copy from one section of the
DNA that usually correspond to a single
gene. </span>
