Answer:
b. the 20 amino acids found in proteins differ in the composition of their R groups, which may be either polar or charged.
Explanation:
Since the proteins are polymers joined by a big number of amino acids, all the joins occur the same way because in all the amino acids there is always one part that is exactly the same in all of them.
The rest of the molecule in the amino acids, the R group, is different in each one, that is the characteristic of each one, and this is the part that can give the name and some other chemical properties.

Answer:
<em>The correct option is C) The success of a species depends on the number of offspring that survive long enough to reproduce.</em>
Explanation:
Some species of animals such as the octopus might give rise to many offspring, but these offspring might not survive due to different reasons. Only a few of them will be able to survive until the age where they can reproduce.
On the other hand, the survival rate of offspring which are formed in lesser numbers is more. These offspring are taken care of by their parents usually or are better adapted to live in the environment. Hence, their survival rate is more.
Sporadic cancer is cancer by chance, there is no relative with the same type of cancer. Familial Cancer, on the other hand, is a combination of genetic and environmental factors. Hereditary cancer, moreover, happens when a defective gene is passed from parent to child. Breast and ovarian cancer fall under hereditary cancer though it does not mean that if either of the parents have these types of cancer, the offspring will definitely acquire it. If either of the parents has the defective gene for breast or ovarian cancer, the offspring has higher chances of having the aforementioned cancer.
