Answer:
The correct answer is movement; structure.
The muscular system helps with <u>movement</u> and the skeletal system helps with <u>structure</u>.
Explanation:
The human muscular system constitutes 40% of the total weight of our body and is made up of three types of muscles, which, together with different tendons and thanks to their contraction capacities, allow us to move. The muscular system and the function of the muscles allow the movement of our body and it is the one that works in tune with other systems of our body to guarantee normal general functioning..The skeletal system is the set of organs that support, shape, structure and protect the body. The skeleton is a dynamic structure, specifically the axial skeleton, it is to serve as a support or as a scaffold that supports the organs and structures of the body. This is how bones together with muscles work as a team to allow the mobility of the human body.

Diffusion is the movement of particles from a high concentration area to a low concentration area.
Things that can go through a membrane are ions (charged), small polar molecules. Big molecules can't go through the membrane due to its large size and disrupting the membrane.
Passive transport is the movement of substances acrpss the cell membrane w/o the use of energy. Active transport needs energy to move substances across a cell membrane.
If the size of a cell increases it will be more difficult (all other things being equal) for diffusion to transport materials out of the cell. Therefore, less of the cell's interior will be able to come in contact with the cell's surface. If less of it comes in contact, less of it can cross the cell membrane.
hope this helps and please mark me as brainliest please
Answer:You may feel hungry frequently if your diet lacks protein, fiber, or fat, all of which promote fullness and reduce appetite. Extreme hunger is also a sign of inadequate sleep and chronic stress. Additionally, certain medications and illnesses are known to cause frequent hunger.
Explanation:
"Hunger hormones" (ghrelin) in your blood and an empty stomach signal the brain when you're hungry. Nerves in the stomach send signals to the brain that you're full, but these signals can take up to 20 minutes to communicate -- and by that time, you may have already eaten too much.
