Its B.cell wall
ribosomes are used to synthesis proteins and other components required for cells
endoplamsic reticulum is where the ribosomes are its a structure that helps to prepare the components and to bring them to the golgi body
the cell wall is only present in plants (cellulose) and fungi (chitin) and it helps plants to regulate their water intake physically
the cytoplasmis present in all cells as the medium which organelles are suspended in and in contact with
hope that helps <span />
Autoregulatory neural and endocrine mechanisms activate after blood loss to compensate for the loss and restore homeostasis.
Neural mechanisms involve blood pressure and blood chemistry. Cardiac centers and vasomotor centers may increase the blood flow and cardiac output (sympathetic) or decrease the blood flow and cardiac output (parasympathetic). Peripheral vessels are also constricted and nor epinephrine decreases flow in the arteries and decreases the flow in the veins.
Endocrine control acts in the renal and adrenal organs, the brain and heart. RBCs, renin/angiotensiogen/aldosterone, catecholamines, antidiretic hormone, atrial natriuretic hormone regulate blood volume and blood pressure by keeping the fluids in the cardiovascular system. It also initiates vasoconstrictors or vasodilators.

Humans are also part of ecosystems and if they cease to exist, human well being will be affected.

</span>Photosynthesis is a process wherein light energy is converted into chemical energy.
<span>Plants use the light energy coming from the sun and make food and other cellular organic compounds that will be used for certain types.
