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.
False, it happens through the light independent reaction.
Answer: c. This mating will demonstrate that these elephants are members of the same species and will produce fertile offspring.
Explanation:
A species is a group of organisms capable of interbreeding to produce viable offsprings. The Sri Lankan Elephant and the Indian Elephant are the same species so, they will produce fertile offsprings. Because they are from different geographical location does not mean they won't mate and produce fertile offsprings.
Answer:
they are ions of their atom.
