Answer and Explanation:
The dendrite connects the axon of one neuron with the dendrite of another neuron to relay messages. Neurons transmit information to each other throught synaptic gaps. The cells release chemicals known as neurotransmitters to communicate with one another.
A synapse functions to allow transmission of nerve impulse from neurone to neurone. Acetylcholine is a substance that is used in impulse transmission. When an impulse reaches the synaptic knob, it stimulates the vesicles to move towards the pre-synaptic membrane releasing acetylcholine. The transmitter substance makes the membrane permeable.

Answer and Explanation:
To determine the overall health of the alligator pond, Mr. Ortiz should carry out the following tests:
pH is extremely important in this type of research as a reduction of pH could lead to a higher availability of toxic metals that may be absorbed by aquatic organisms such as alligators and fish species.
<em>pH is acceptable in a range of 6.5 to 8.2.</em>
- <u>Nitrates and Ammonia (NH3) levels</u>
Oversaturation of nitrates and ammonia could lead to the death of organisms that are crucial for the maintainance of a healthy pond and for the balance of the food chain.
Moreover, it could lead to algal blooms that result in a lower concentration of oxygen available for other organisms.
<em>Over 0.2 per L could be lethal</em> to some fish species that are also important for the health of the alligator pond.
<em>Less than 0.1 </em>indicates a healthy alligator pond.
- <u>Bacterial coliform test</u>
This test determines the amount of bacteria that comes from waste (animal or human), which could lead to mild to serious bacterial infections and diseases.
If it is a healthy pond, the results should indicate <em>less than 10 fecal coliform bacteria/100 mL.</em>
