The correct answer is antigens and epitope.
An antigen is a substance which triggers an immune response in an organism. This can be either a foreign substance, such as a pathogen, or a specific part of the host organism (in this case this is an autoimmune response). The presence of an antigen activates a specific part of the immune system, called antibody. Each antigen has a specific antibody, which is tailored by the immune system accordingly. More specifically, the antibody has a specific structure, called paratope, which is complementary and binds like a key to a specific structure of the antigen, called epitope.

Explanation:
A population in biology, is simply a group of individual organisms of the same species sharing a common gene pool that are dwelling in a similar habitat or geographical area. The individuals of a group have the capability to interbreed with each other to produce viable offspring that are fertile, however, interbreeding with other similar groups is usually not successful. Also, genetic variation exists within individuals of a population. Examples of a population are: mountain gorillas in Africa, African elephants etc.

Answer:
Bone remodeling keeps bones strong as osteoclasts break down bone and osteoblasts rebuild it. This process replaces as much as 18% of bone each year. Bone recycling helps the body to regulate blood calcium.
Explanation:
Bone tissue is a type of specialized connective tissue that is in constant change and renewal due to the activity of its cells. Besides serving the composition of bones and, therefore, the skeletal system, it also functions as a calcium reservoir that can be used when needed.
