Answer:
Guard cells
Explanation:
Guard cells are the cells that are found around the openings of the stomata, their functions is that they regulate the opening and closing of the stomata. These cells are always fill with latex which is of high percentage of water, therefore when the intake of water is low, the functionality of the cells will be affected.
And it must be noted that, the stomata is very important in the exchange of gases, that is a process where oxygen is released and carbon dioxide is absorbed. Therefore when the cells are affected, the gas exchange will also be effected.
<h3><u>Answer;</u></h3>
= 71.96%
<h3><u>Explanation</u>;</h3>
1 mole of CS2 = 76.133 g
1 mole of SO2 = 64.06 g
1 mole of CS2 reacts with 3 moles of Oxygen to produce 2 moles of SO2
Moles of CS2 in 12.5 g = 12.5/76.133
= 0.164 moles
Mass of SO2 = 0.164 mol × 2 × 64.06
= 21.01168 g
Therefore;
Percentage yield of SO2
= 15.12/21.01168 × 100%
<u> = 71.96%</u>
carbon dioxide leaves the body through their respiratory system (lungs)
