Answer:
Botulism toxin disrupts motor control <u>by blocking the release of acetylcholine by motor neurons. </u>
Explanation:
Acetylcholine is the principal neurotransmitter in motor neurons. If there is no release of acetylcholine from the presynaptic motor neuron, the ion channels will not open. If the ion channels do not open, Na+ cannot enter the postsynaptic membrane to start an action potential. As a result, the muscle can not move.
The ion channels have a specif receptor for acetylcholine. When acetylcholine binds to the receptors, the channels open. With the ion channels open, Na+ can enter the postsynaptic membrane to start an action potential. This does not happen in the presence of botulism toxin since it blocks the release of acetylcholine.

<u>Answer</u>: predator and prey
<u>Explanation</u>:
The described graph illustrates the cycle of a predator and prey population. The population curves for predator and prey are not synchronized with each other and their amplitudes differ.
Changes in the prey population will not result in immediate or exactly identical changes in the predator population.
In the attached image, the red line represents the prey population and the blue the predator population. As it can be observed, when the prey population increases in size, the predator population size increases too.
However, this increase is not of the same size and is delayed in time. The predator population will continue to increase even though the prey population has started to decrease.
This has to do with the fact that the adult predators mated and gave birth when the food availability was still high. However, these new young individuals will not survive and reproduce due to decreasing prey. As the prey continues to decrease, more and more predators will perish.
The same cycle will then repeat over and over again.
The correct answer would be option D, that is, fertilization during the study.
The experimental error refers to the dissimilarity between a measurement and the true value or between the two measured values. Experimental error is determined by its accuracy and precision.
A variation in data, or error, basically signifies whatever results in the data to be imperfect, not the human mistakes. In order to correct this, there is a need to get familiar with the unavoidable sources of error and how they take place so that one can reduce their effect and get the best probable data.
