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:
E. The length of cells in the elongation and mature zones would be larger in the control group.
Explanation:
The length of cells in the elongation and mature zones would be larger in the control group this is because of the increase in the solute concentration of the hydroponic growth medium which excluded the roots.
This reduces the amount of water that moves into the root system of the plants and nutrients which imitate drought conditions, this imposed drought leads to a decrease in the plant growth.
