Answer:
As the spies of a cactus are modified leaves, they have ar spaces.
Explanation:
However, leaves of cactus are not like every other leaf. These leaves are in the form of spines to save the amount of water that the cactus needs.
Most of the amount of water, cactus s saving in its root. Also, the stem of a cactus is used for making food, and this is also the way of saving the water.
Answer: Where would the blood come from if there were a blockage just posterior to the middle cerebral artery on the left? If blood could not get to the middle cerebral artery through the posterior circulation, the blood would flow around the circle of Willis to reach that artery from an anterior vessel.

Answer:
See the answer below
Explanation:
(a) One of the inorganic sources of new plant mass for the light-grown plants is the atmosphere. The <u>carbon in the form of carbon dioxide in the atmosphere is sequestrated into the body of the light-grown plants through a process known as photosynthesis</u>. During this process, the inorganic carbon dioxide becomes fixed into the body of the plant through a series of steps that include both light-dependent and light-independent. The overall equation of the process is as below:

As more plant mass is being gained by photosynthesis, some of the gained mass is also being lost to energy generation through a process known as respiration.<u> Respiration is like the complete opposite of photosynthesis but a gain in mass is still possible because the rate of photosynthesis is more than the rate of respiration in the light-grown plants.</u>
(b) The chemical reaction that can be held responsible for the decrease in mass of the dark-grown plants is<u> respiration</u>. Some of the mass is lost to energy generation and this mass cannot be recouped by adequate photosynthesis due to light limitation. The energy is needed to metabolic processes that would keep the plants alive. The equation of respiration is as below:
