In the human body, the nervous system provides impulses which direct muscles to move, while the contraction of muscles physically produces the movement. Which additional system determines the movement the body will make?
(A) skeletal system
(B) immune system
(C) endocrine system
(D) reproductive system
Answer:
C is the correct answer.
Explanation:
You can automatically eliminate B and D because they have little to do with the movement of the body. And it's not A because the skeletal system doesn't have the signals to tell the muscular system what to do.
The kidneys are organs of the body that work to maintain homeostasis. Which of the following is most likely to occur if a person’s kidneys suddenly stop functioning?
(A) a decrease in blood volume
(B) an increase in urine production

A proper balance of oxygen and carbon dioxide must be maintained in the human body to survive. Which of the following body systems is responsible for taking in and releasing these gases to ensure homeostasis?
A. Digestive System
B. Excretory System
C. Circulatory System
D. Respiratory System
Answer:
D. Respiratory System
Explanation:
The system acts to reverse the direction of change. Since this tends to keep things constant, it allows the maintenance of homeostatic balance. For instance, when the concentration of carbon dioxide in the human body increases, the lungs are signaled to increase their activity and exhale more carbon dioxide, (your breathing rate increases).
The system that is responsible for taking in and releasing these gases to ensure homeostasis is respiratory system. The correct option is D.
What is respiratory system?The respiratory system soaks up oxygen from the environment humans breathe as well as remove carbon dioxide.
The lungs are basically the primary organs of the respiratory system. The nose, trachea, as well as breathing muscles are respiratory organs too.
The respiratory system encompasses the muscles that power up the lungs.
These components usually work altogether to transport oxygen throughout the body and remove waste gases such as carbon dioxide.
The lungs are the primary organs of the respiratory system. The nose, trachea, and breathing muscles such as the diaphragm and intercostal muscles are also respiratory organs.
Thus, the correct option is D.

True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
1. I belive number 1 is false because as shown in the picture, it is a chemical energy going out of the factory but I don't think it is going into a mechanicalm energy. This is the definiton of mechanical energy. "Mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system."
2. I belive this is true because yes, solar energy is being transfered to a chemical energy. The sun, which is the solar energy, is being transferred in phtosynthesis.
3. I belive arrow C is a release of carbon dioxide because from the factory it is releasing to the air causing climate change.
4. I belive arrow F and E because it is showing the carbonation cycle.
5. Belive B and D because it blances the mass and energy.
