Answer:
(2) diffusion
Explanation:
Diffusion is a process in which molecules moves from a region of higher concentration to the region of lower concentration. In this condition, plant roots contain high concentration of nitrates than soil so nitrates moves from roots through semi-permeable to the soil by the action of diffusion until the concentration is uniform or equilibrium.
The defining abiotic factor of deserts is "A) the amount of rainfall" which is relatively very little in deserts. Desert climates can be found almost everywhere in the world.
Answer:
Active transport:
- Diffusion (one to far left)
- Facilitated diffusion (the one with glucose)
- Osmosis (the one with water)
Passive transport:
- Protein pump (one to far right)
