Answer:
A
Explanation:
There are different mechanisms for transport of molecules across the cell membrane. One kind of this transport is facilitated diffusion, this is a form of passive transport, not requiring any ATP (the opposite would be active transport, where it does require ATP.
Simple diffusion does require special transport proteins, and neither does osmosis. Filtration is a technique used for sterilisation of water, where any impurities can be drawn out of the liquid
Answer:
It will take him exactly 12 weeks
Explanation:
If he already has 65 you subtract that from 245 and you get 180
You divide 180 by 15 to get the number of weeks and you get 12
Aerobic respiration to lactic acid fermentation, lactic acid is the reason your muscles get sore after a workout
Answer:
D
Explanation:
Diffusion and osmosis are both passive forms of transport because there is no energy need to transport something such as water from an area of high pressure, to an area of low pressure.
