The amount of water on the planet is fixed; it neither increases or decreases. Glaciers are sheets of moving ice. This water to form these extensive sheets must come from somewhere. The water comes from the most extensive store on the planet; the oceans. Ice Ages always corresponds to periods of low sea level because much of the ocean water is is land locked as glaciers.
Answer:
c. Acclimatization
Explanation:
<u>Acclimatization</u> : Various physiological readjustments and compensatory mechanisms in body that reduces the effects of hypoxia in permanent residents at high altitude. These are basically the respiratory and hematopoetic adjustments to long-term move to high altitude.
As the Chum Salmon (oncorhynchus keta) are born in freshwater water constantly diffuses into the body and ions are lost from the body while in the sea water, they lose water.
As alot of changes are occrun in the cells of the gills of chum salmon, that is acclimatization as various physiological readjustments are being made.

Answer:
b. although some primates have the ability to transmit meaning from one individual to another, this always happens within a species, never between species; this is similar to humans, since humans do not really understand other animals either.
Explanation:
Transmission of information or message often takes place between species of same kind.
Human can better understand the language, sounds, signs made by fellow human and not sounds from other species of animals or other organism, this is because language or system of communication is attached to a particular domain or organism of a species. Birds communicate differently from a Goat, human does likewise from other primates.
The system of communication is used to a particular locality and if not learned it is not understandable by another species of organism.
The answer is NAD+.
NAD+ is the primary oxidizing agent in the glycolytic pathway. Oxidizing agents gain electrons and thus, they are reduced in a reaction. In the glycolytic pathway, NAD+ server the oxidizing agent. It accepts electrons from the molecules, such as some intermediates of the glycolytic pathway. As the result, it is reduced to NADH which can serve in some reactions as a reducing agent.
