Answer:
The organism will pass on the traits to their offspring. If the offspring also has an increased chance of survival it will have a higher chance of passing on the traits. Over a long period of time the entire population can inherit this trait.
Explanation:
According to the theory of natural selection organisms with beneficial traits are more likely to survive to the reproductive stage and pass on the beneficial gene to their offspring. <em>Natural selection selects beneficial traits.</em>
Answer:
Because it uses a carrier at the cell membrane
Explanation:
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.
