Comparisons of protein similarity among species can reveal the degree of genetic kinship because:
a. the number of protein variations is limited
b. specific amino acids are dictated by known nucleotide sequences.
c. DNA is made by directions stored in proteins.
d. protein can be hybridized with DNA
e. gel electrophoresis converts proteins to nucleotides.
The modern synthesis hypothesis regarding evolutionary rates states that:
a. Evolutionary change in populations can be a very gradual process for some species but in others it can occur quite rapidly over relatively few generations.
b. Evolutionary change in populations is a very steady, gradual process taking place over millions of years.
c. Evolutionary change occurs at a minimal, background level and cannot be measured by modern methods.
d. Evolutionary change in populations only occurs after a major disturbance to an environment and then occurs quite rapidly.

First answre is b. specific amino acids are dictated by known nucleotide sequences.
Proteins are strings of amino acids. The specific amino acids strung together are determined by the sequence of the nucleotides in the DNA. These specific sequences are called codons. Each amino acid has its own specific codon that codes for it.
2nd answer is a. Evolutionary change in populations can be a very gradual process for some species but in others it can occur quite rapidly over relatively few generations.
The reason for this is because different populations of species will experience different ecological pressures, and thus be affected in different ways. These ecological pressures can cause certain species to need to adapt more quickly than others.
