Answer:
2, 1, 4, 3.
Explanation:
The cell membrane potential may be defined as difference in the electric gradient inside and outside of the cell. The ions are important to create the voltage difference.
The nerve impulse transmission occurs by its propagation. The cell is at the resting membrane potential. The opening of sodium ions causes the inward diffusion of the ions. This causes the membrane potential become more positive and the cell depolarize. Then potassium ions starts diffuse in the cell and sodium ions move out. This causes the repolarization of cell.
Thus, the correct sequence is 2, 1, 4, 3.
Answer:
See below:
Explanation:
The process where certain organisms excrete nitrogenous waste in the form of ammonia is called ammonotelism.
Scientists have discovered the specific mutation that famously turned moths black during the Industrial Revolution. In an iconic evolutionary case study, a black form of the peppered moth rapidly took over in industrial parts of the UK during the 1800s, as soot blackened the tree trunks and walls of its habitat.
The question does not provide any options, I found the options and here are the options:
<span>A) Sights often create strong emotional responses.
B) The cingulate helps you express your emotional state.
C) Emotional states can alter our blood pressure.
D) Your amygdala judges facial expressions for danger.

The correct choice is "A", " Sights often create strong emotional responses".
The sense which is more directly
involved with a person’s limbic system is the sense of smell and because of
that it is the sense of smell which should or is more likely to initiate
emotional response.
It reduces the demand of electricity because if people want to decrease the amount of air pollution they would stop using things that would cause pollution for example, people stopping to use gasoline powered cars and use electric cars more, therefore the demand for electricity will go low since lesser people will be using it.
