Answer: Neurotransmitter
Explanation:
Neurotransmitter are refers to as chemical messengers, which are secreted by the nerves cells, to stimulate neighbouring neuron, thereby allowing impulses to be passed from one cell to next, throughout the entire nervous system. Neurotransmitter are released by the axon terminal, after an action potential has reached the synapse, which the is the neuron transmit signal. Neurotransmitter are often released when, electric signal gets to neuron, it triggers the vesicles that contains neurotransmitters, which will split neurotransmitters into the synapse.
The abiotic factors in salt marshes include:
1. High, variable salinity
2. Low oxygen levels
3. Turbidity
4. Varying temperature
5. Sulphide toxicity
Salt marshes occur in zones between low and high tides. Salt marshes are periodically flooded by tides , so the plants living there have had to adapt to being submerged in salt water.
Only a limited number of plant and animal species can tolerate the harsh conditions of salt marshes and therefore salt marshes are generally poor in species.
Answer: It's most likely Gamma Rays.
Explanation:
Answer:
What does it mean for a cell to have an optimal pH range?
it will only function properly at a neutral pH of 7.
Explanation:
Every cells performs best at optimum pH which is neutrality. Acidity or alkalinity affect cell's performance which calls for optimum range in order to get the best performance
