Answer:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
Answer:
Osmosis
Explanation:
Osmosis is the process of movement of water molecules from the region of its higher concentration (hypotonic) to that of the lower concentration (hypertonic).
Here, two solutions of different solute concentration are separated by a membrane that allows the movement of water molecules through it. Osmosis is a passive movement and does not require an input of energy as it is driven by the concentration gradient.
Answer:
D. Control the blood flow into the capillary bed
Explanation:
The degree of filling of the capillary bed and level of arterial pressure within the vascular system is determined mainly by the degree of tonus (firmness) in the smooth muscle of the arterial wall. Arterioles have relatively narrow lumina, thick muscular wall and precapillary sphincter.
Via collateral circulation. This is an alternative route of blood circulation around the brain whenever one pathway is blocked or narrowed. The arterial arrangement of the brain are symmetrically designed in such a way that continuous blood flow the brain is ensured. The cerebral arteries (anterior and posterior) can be interchangeably shared if one of them is restricted. This means that if one artery is blocked/narrowed the other can accommodate the blood flow needed by the brain.
