What is homeostasis? How do cells use both diffusion and osmosis to help maintain homeostasis?

Biology

arlik [135]3 years ago

Answer:

Osmosis is the process cells use to move water molecules in and out of the cell through the cell membrane. When cells are put in different environments they will try to maintain an equilibrium with the water concentration outside the cell. Through osmosis the cell will lose or gain water molecules to become equal to the concentration in their environment.

Which structure connects the knee joint at both sides and prevents its dislocation?
Readme [11.4K]

Collateral ligaments are <span>two strap-like ligaments that act to stabilize the hinge motion of the knee, preventing any lateral or medial movement. It is the structure that connects the knee joint at both sides and prevents its dislocation. There are two types: Tibial (medial) collateral ligament and Fibular (lateral) collateral ligament.</span>

Ahat [919]

Answer:d) contracting her pupils and increasing secretion of stress hormones.

Explanation:

Peripheral nervous system consists of 3 major neuronal levels: vegetative (reticular formation and brain stem), limbic system and neocortical level. The RAS is the link between the brain and the spinal cord.

Brain stem consists of pons, medulla oblongata and mesencephalon. Brain stem is responsible for involuntary functions such as heart beat, respiration and vasomotor activity. Limbic system represents the emotional control center. It consists of thalamus, hypothalamus and pituitary gland and maintains homeostasis. Neocortical part processes sensory information and regulates emotional responses.

Autonomic nervous system (ANS) regulates visceral activities and organs (circulation, digestion, respiration and temperature). ANS has two divisions: sympathetic and parasympathetic nervous system.Parasympathetic nervous system regulates homeostasis via the release of acetylcholine (Ach). Parasympathetic nervous system is responsible for energy conservation and relaxation.

There are three stages in the stress response: immediate effects of stress, intermediate effects of stress and prolonged effects of stress.

Why does the reduction of the dye DCPIP work best using the chloroplasts whose outer envelopes have been damaged during preparat
Stolb23 [73]

Answer:

NADP is the cofactors in photosynthesis which loses electrons,becomes reduced(NADPH) in photosynthesis. It transfer  electrons  in reduced form(NADPH) into the stroma of the chloroplast. The H is splits into e- and H+

These electrons for the ETC chains, generates the PMF for pumping H+ as protrons into the thylakoid  intramembranes.

Outer membrane covers  the intramembrane space, between these two membranes layers. The protons in the intramembrane space generate the electrochemical gradient for the supply of  the energy used by ATPase synthase for ATP synthesis from phosphorylation with ADP.

The chloroplast is made up of both the outer and inner membrane,separated by the intramembrane space. The walls of the intramembrane space is guided by the outer envelope. 

Therefore with the outer envelope removed, the intramembrane is exposed,more protons(H+) are released, but can not be held in the outer envelope to form electrochemical gradients,beacause the intramembrane space is now permable.

Thus   the rate of reduction of DCPIP is faster.The  color changes to colorless increases when reduced , from blue color.

RideAnS [48]

Answer:

C and E

Explanation:

A wavelength, when drawn like this, is between two points in the exact same spot of the wave, but in different positions. Here, C is the middle when the wave is going "down" into the trough. The next point at this position is point E, giving us our answer.
