Answer:
The correct answer is: Homeostasis.
Explanation:
Homeostasis is a key element in the correct functioning of the body, as it groups different processes that consist of regulating biological systems in order to maintain certain aspects of the body constant. If homeostasis were to fail, the body would sicken.
Homeostasis is controlled by two important systems: the nervous system, and the endocrine system. While they have many differences (for example, the nervous system's response is quicker and lasts less than the endocrine system's response), they share the capacity of sending messages to different parts of the body to generate responses that help us adapt to the varying conditions of the environment.
Examples of homeostasis include the regulation of body temperature, pH, and blood sugar levels (glycemia).

it must be the policy of the United States to support free people who are resisting attempted subjugation by armed minorities or by outside pressures.
I would say that two products of the earth are coal and petroleum and when they are burned say in a car or a power generating facility they can be converted to fossil fuels.The burning of these fossil fuels are causing too much greenhouse gases and making the earth's temperature rise and resulting in more extreme weather so fossil fuels need to be phased out so the earth will remain inhabitable for humans.
Answer:
Relative velocity simply means velocity relative to a certain observe point, in this case, the river shore.
This is a type of complex movement; a boat is moving with a certain velocity, let's say 8 m/s. However, the river this boat moves on also has its velocity, let's say 2 m/s. Since the shore isn't moving, the velocity of the boat relative to the shore will be simple resultant velocity of the boat's and the river's velocities.
Let's illustrate this with two examples:
1) if the boat is moving downstream both are moving in the same direction, so the resultant will be 8 m/s + 2 m/s = 10 m/s.
So, any spectator looking at the boat from the shore will think its velocity is 10 m/s, when in reality it's 8 m/s.
2) if the boat is moving upstream, these two velocities have opposite directions, so the resultant will be 8 - 2 = 6 m/s
So, as a short summary, relative speed is an object's speed in regard to another chosen referent point.
