An environmentalist wishes to preserve the environment is the correct answer
Answer:
As I am the member of the city council, I would prefer nuclear power plant as the best for community instead of using a new coal-burning plant.
Explanation:
- The nuclear plant don't emit harmful gasses like carbon dioxide, sulfur dioxide, nitrogen oxides, mercury, or other toxic gases which is harmful to the living beings.
- It is the alternate method to decrease the rate of air pollution so it is friendly to the environment as well as Eco-system.
- Although the nuclear plant is expensive but the requirement is less than Coal-burning plant.
The order from the longest to the largest will be; Eon, Era, Period, Epoch.
Eon is the longest division of geologic time. Epoch is the shortest division of geologic time, only present in Cenozoic Era. Era is the second longest division of time, marked by sweeping changes in the fossil record. Period is the time division which is longer than an epoch but shorter than an Era.
Answer:
The type of ion channel opened will be the most important factor.
Explanation:
At certain occasions a given neurotransmitter can combine with a K+ chemically gated channel and at certain occasions the same neurotransmitter can combine with a Na+ chemically gated channel. Thus, the same neurotransmitter can produce depolarization if it opens the Na+ channel and a hyper-polarization if it opens the K+ channel.
In these situations, the structural make-up and sensitivity of the postsynaptic cell really determines if the neurotransmitter will inhibit (depolarize) or excite (depolarize) the postsynaptic cell. It is more essential to know the kind of channel, which opens than the particular identity of the neurotransmitter.
Natural selection acts on an organism's phenotype, or physical characteristics. So it depends what organisms it might affect.
