2)Movement of water across a cell membrane
is correct
Haploid cells join to form an organism that has a complete set of chromosomes
The answer is: B; the diffusion gradient in cell B is steeper
Cell B actively converting oxygen to water in cellular respiration, therefore the oxygen concentration would be much less when compared to oxygen concentration of cell A.
Diffusion will allow molecule to move from container with higher concentration to container with lower concentration. The difference in concentration will increase the speed, so the speed of oxygen diffusion to cell B would be faster.
Answer:
mass and distance
Explanation:
As the two objects get further away, the distance between them increase and the strength of the gravitational force decreases. If the distances decreases, the force will increase. The bigger the object, the greater the force.
