<h2>Answer:</h2>
The compound is known as the neurotransmitter or messenger chemicals.
<h3>Explanation:</h3>
- Neurotransmitters are the chemicals a type of messenger which is used to transmit information from one cell to the next cell.
- Some hormones are also known as messenger chemicals.
- The nerve cells are not linked to each other while they are separated from each other by a space known as synapses.
- The electric potential signal is converted into chemical signal by the release of neurotransmitters.
- These neurotransmitter signal next cell to produce equal amount of electric signal in nerve cell.
Answer: Im thinking the answer Is B) Bar graph?
Explanation:
Answer:
P + Q2+ -> no reaction
R + P2+ -> R2+ + P
Q + S2+ -> Q2+ + S
S + P2+ -> S2+ + P
S + R2+ -> S2+ + R
S + Q2+ -> no reaction

Hertz is units for frequency. (waves per second)
wavelength = speed/frequency
if you're given the speed use that to calculate, if not then you can probably assume it's a wave of light and use the speed of light (3x10^8 m/s) to calculate.
wavelength = (3x10^8)/(1.28x10^17)
= 0.000000002 m
= 2.34 nm
