A directional movement of water is ocean currents
The correct answer is: Release of neurotrasmitters from the synaptic vesicles
Action potential travels through the membrane of the presynaptic cell causing the channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine), Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells.
B muscle cells because lactic acid is what makes your muscles sore when there isn’t enough oxygen
Answer:
Explanation:
Lenticels ( tiny openings in the stem of plants through which gases are exchanged and water molecules in form of vapor escapes from the plant into the atmosphere)
Active transport uses energy but diffusion and facilitated diffusion doesn’t that why they differ from each other
hopefully that helps :)
