Answer:
Calcium channels.
Explanation:
The arrival of action potential at the presynaptic neuron, cause the opening of Ca+ channels, at the presynpatic neuron membranes. This leads to influx of Ca+ . The latter caused the Acetycholine contained vesicles in the presynaptic neuron to migrate to the tip of the presynaptic neurons, and fused with the neuronal membrane to empty their contents into the synaptic cleft.
Answer:
The given statement is false because there is no involvement of solar energy during electron transport chain.
Explanation:
Solar energy is utilized in photosynthesis but not in electron transport chain(ETC).During ETC electrons are liberated from the reducing equivalent such as NADH,FADH2.The liberated electron moves from one electron carrier to another until it(electron) reaches the terminal electron acceptor oxygen.
The movement of electrons occur simultaneously with the movement of proton(H+) resulting in the generation of proton motive force(PMF). This proton motive force helps in the phosphorylation of ADP to form ATP with the reduction of o2 to water.
Climate is defined as the general weather conditions prevailing in an area. Therefore, out of your answer choices, the correct answer would be "C: The Average weather conditions of a region over a long period of time"
Hope this helps!
Answer:
true
Explanation:
just report me if im wrong
The high surface tension of water, so as many other of its properties, is due to the strong attraction force created by the hydrogen bonding, which is the attraction between neighbors hydrogen atoms (with a partial positive charge) and oxygen atoms (with partial negative charge)
Answer is its hydrogen bonding.
