Answer:
The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.
Explanation:
The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.
Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.
During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.
Answer:
A scientist's response to the increase in food poisoning sick patients should be examining the type and source within the foods consumed.
Explanation:
Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.
Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.
The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to <u>eliminate the source and avoid new cases</u>.
- <em>The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond. </em>
Tooth length is influenced by natural selection
