Just like other cells, the part of the bacterium that is able to interact with its outside environment is its cell membrane. Generally, the main function of the cell membrane is for barrier and protection. This decides which molecules will be allowed to permeate or not. Hope this helps.
Transpiration is the process where water evaporates from the pores of
leaves. Because of the charges of water molecules (I don't know the
specifics), the evaporation of water molecules leads to others being
pulled up the xylem tubes towards the leaves - hence transpiration is a
necessary evil because it involves constant water loss, but is also
useful for providing water for photosynthesis, support of cells by
osmotic intake of water and cooling for optimum enzymatic efficiency.
Therefore as transpiration increases (which will be if temperature is high to cause more evaporation, windspeed is high to carry water vapour away and humidity is low so diffusion of vapour away from the leaf is more favourable), the intake of water will also increase because it is literally pulled up the xylem tubes from the roots to the leaves.
That's how I understand it anyway :)
I hope this helps
The answer is 1.9 millimeters.
Solution
To get the mL value, you have to multiply the following:
(18.6 kg)(<span>5 mg/kg)(3mL/150mg)=mL
The technique here is that you have to think of isolating the unit you are finding and then you have to find a way that you can divide the units until you will find your needed unit. In the solution, you can see that kg/kg=1 and mg/mg=1 so the only unit left is mL. There you can get your answer. Don't be confused by the reciprocal of 150mg/3mL because it is only to get your needed answer.</span>
