lisabon 2012 [21]

Answer:

Positive feedback.

Explanation:

An increase in body fluids causes increase in kidney filtration which leads to higher production of urine, this type of feedback is known as positive feedback because when there is increase in the output, this is called positive feedback while on the other hand when there is decrease in the output we called it negative feedback. So we can see that the output of the kidney is higher concentration of urine so we can say that it is a positive feedback.

In your own words, give a brief overview of the process of photosynthesis. Include where each phase place within a plant cell.
vodka [1.7K]

Answer:

Photosynthesis has two parts: the light-dependent reactions and the dark reactions (the Calvin cycle). Photosynthesis in a general sense, uses CO2 and water to create C6H12O6 (glucose) and oxygen. The light-dependent reactions use water to make oxygen, and a reduced energy carrier (NADPH) is also created. The Calvin cycle uses carbon dioxide and ATP to create G3P for glucose.

The light-dependent reactions occur on the membrane of the thylakoid and also involve shuttling electrons across different complexes (photosystem II and photosystem I), eventually causing ATP to be created with a proton gradient.

The light-independent reactions/Calvin cycle occur in the stroma of the chloroplast and also involve shuffling carbons around. Carbon dioxide is processed in three stages, and glucose is made from 6 CO2.
