- This tool of smart growth helps in developing the cities by preserving the available spaces for tomorrow, this process is also known as the sustainable development.
Answer:
low level of calcium would result in fewer signals sent between pre and post synaptic cells.
Explanation:
The calcium has a main role in signal transmission mechanism and here is the mechanism :
1-the impulse reaches the synapse (depolarization which is a voltage change).
2-the voltage gated calcium channels open and let calcium flow into the cell.
3-the calcium causes the synaptic vesicles to rupture and release chemical transmitters which cross the synaptic cleft and finally bind to receptors on the post synaptic cell (transmitting the signal)
so it's obvious that if calcium concentration decreases, the signal transmission also decreases.
Answer:
a wasteland
Explanation:
if an ecosystem did not have interactions it would not be an ecosystem because it takes different parts cooperating together for it to function.
...strong hydrogen bonds between the oxygen and hydrogen atoms of neighbouring atoms increases the amount of energy needed to cause water to change states.
