Answer:
plasma membrane/ cell membrane
A grasshopper may use the energy to move around, store it or use it for nutrients. There may be many answers to this.
63 in water 100/g KNO3 Potassium nitrate
Alright, so the highest temperature at which water is most dense id 4 degrees Celcius, if it gets lower than that, water would start to expand. So at 5 degrees, it would just be rain.
Answer:
Plasma membrane is the semi-permeable membrane that allow the movement of some selected particles only against the concentration gradient or along the concentration gradient.
Different substances can be move through the diffusion, active process and passive process. The hydrogen in the vesicle has been moved through the facilitated diffusion. In this process, the hydrogen ions will move along the concentration gradient without the requirement of energy but requires the channel protein for its transport.
