Answer:
Partial pressure of He = 73 kPa
Explanation:
Given:
Total pressure = 125 kPa
Partial pressure of Ne = 31 kPa
Partial pressure of Kr = 21 kPa
Find:
Partial pressure of He
Computation:
Total pressure = Partial pressure of Ne + Partial pressure of Kr + Partial pressure of He
125 kPa = 31 kPa + 21 kPa + Partial pressure of He
Partial pressure of He = 73 kPa
The answer is; active transport
This means that energy is expended in the process. Because large protein cannot be transported through protein channels in the plasma membrane for being too big, they are transported through endocytosis. This means a vesicle merges with the plasma membrane and forms an invagination that engulfs the protein. The vesicle then encloses with the protein inside and moves into the cell.

The statement describes from the relationship between multiple approaches and familiarity with similar work. The answers is would be last sentences. D. Multiple approaches may occur because scientists develop similar interests independently.
Answer:
Adding 1 mol of NaCl to 1 kg of water lower the vapor pressure of water <em><u>to the same extent</u></em> by adding 1 mol of 
to 1 kg of water.
Explanation:
1) Moles of NaCl ,
Mass of water = m= 1 kg = 1000 g
Moles of water = 
Vapor pressure of the solution = 
Vapor pressure of the pure solvent that is water = 
Mole fraction of solute(NaCl)= 
The vapor pressure for the NaCl solution at 17.19 Torr.
2) Moles of sucrose ,
Mass of water = m = 1 kg = 1000 g
Moles of water =
Vapor pressure of the solution = 
Vapor pressure of the pure solvent that is water =
Mole fraction of solute ( glucose)=
The vapor pressure for the glucose solution at 17.19 Torr.
p = p' = 17.19 Torr
Adding 1 mol of NaCl to 1 kg of water lower the vapor pressure of water to the same extent by adding 1 mol of to 1 kg of water.
