Answer:
Both C and E are reasonable answers.
Explanation:
Homeostasis describes the body's ability to maintain a stable equilibirum. In other words, if the body experiences a stress, it will generate a response that works to counteract that stress and restore itself to how it was prior to the stress.
A. This describes a cause and effect (BP down --> venous return down). It does not describe an active physiological response to counteract the BP drop such as an increase in heart rate. Not homeostasis.
B. Again, a cause and effect is described. Blood vessel walls becoming thinner is not a response to counteract increased BP. Not homeostasis.
C. Here a response to a stress is described. Men are drinking more water. The body responds by getting rid of that water, restoring the body to its former state. This describes homeostasis.
D. This sounds like homeostasis, but it's actually the opposite of what happens. Dilation of peripheral blood vessels is a way for the body to get rid of heat. This is the opposite of what you would want if the body got colder - it would make the stress worse, which is the opposite of homeostasis. In actuality the response to cold temperature is constriction of blood vessels to preserve heat.
E. This deescribes homeostasis. The stress is increased glucose. The body's response to manage it is to release insulin, which helps remove the glucose from circulation.

Answer:
A .a net force greater than zero
B. Unbalanced Force
Explanation:
A .When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. So , the answer will be a net force greater than zero .
B . An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. So , the answer will be unbalanced forces .
Answer:
I’m concerned about how the dam will affect the water flow in the river, which can affect the behaviors of fish. I’m also concerned that some fish and aquatic animals might get sucked into the dam. Finally, I worry that the dam could malfunction and cause flooding, which could damage the ecosystem.
Explanation:
It's looks like the right answer looks like this: A ligand produces a response in a cell if it finds the right kind of a. receptor.
