Answer: False
Explanation:
On the contrary, polymers are made up of many monomer units. A good example of polymers is starch, a polysaccharide made up of several units of glucose (monomers) linked by glycosidic bonds
Thus, it is false to say monomers are made up of polymer units

Explanation:
Arctic tundra are found on high-latitude landmasses, above the Arctic Circle—in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, for example—or on far southern regions, like Antarctica. Alpine tundra are located at very high elevations atop mountains, where overnight temperatures fall below freezing.
Answer:
Long necks were a random genetic change and resulted in the gradual increase of organisms with long necks.
Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
