What are the three types of osmosis? What happens during each phase?
Vanyuwa [196]
An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .

A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.

A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.

mixer [17]

Answer:

decreased NADPH production.

decreased sugar production.

Explanation:

The water-splitting complex is associated with PSII and serves as a donor of electrons to the reaction center of PSII. PSII loses its electrons upon trapping of sunlight. These electrons are passed finally to NADP reductase via electron transport chain and PSI. NADP reductase reduces NADP into NADPH. The NADPH formed during the light-dependent phase serves as reducing power in reactions of the Calvin cycle.  

A mutation in the water-splitting complex would result in no electron supply to PSII and thereby, reduced production of NADPH. The reduced NADPH production would limit the supply of reducing power for the Calvin cycle and the sugar production would be decreased.

What two organ systems are most involved in controlling the negative feedback systems of the body?
ololo11 [35]

Answer:

The respiratory system as well as circulatory system (hormonal system) are involved in controlling the negative feedback of our body.

Explanation:

The respiratory system helps in controlling the negative feedback in such a  way that if CO2 level increases in body the system acts in such a way so as to decrease  its level in body . the system attains a normal level by  increasing the blood circulation and increasing the breathing level forcing CO2 outside of our body.

in case of circulatory system, the blood has several hormones released from glands . the most common example is Insulin and Glucagon .

if a person is hypoglycemic then glucagon concentration increases and blood glucose concentration returns to normal and if a person has hyperglycemia then insulin level increases which in turn increases glucose uptake from body and body returns to normal level.
