The best answer is A. The purpose of the cell wall is to hold the cell in a specific shape, usually rectangular or square. For example, a plant cell's wall keeps it rigid so that the plant can stand up.
If the cell does not have a wall, it can easily change shape to accommodate for things coming in and out of the cell.
Hope this helps!
Dry bulb (regular) air temperature is in the scale at the bottom. Relative humidity is in the curves. Trace up from 20 C until you get to 30%, then go from that point straight to the right to the edge where it gives you humidity ratio.
At 30% RH, air has an absolute humidity of 4.5 grams of water per kg of air.
At 40% RH, air has an absolute humidity of 6 grams of water per kg of air.
Need a better picture!! it’s really blurry and can barely read
It can reduce it by 30 percent
