Answer:
the animals
Explanation:
the difference between animal life in the Mesozoic Era and the early Cenozoic Era is that in the Mesozoic Era the reptiles were dominate and in the Cenozoic Era the mammals were dominate.
No.
The Sun can influence the Earth’s climate, but it isn’t responsible for the warming trend we’ve seen over the past few decades. We know subtle changes in the Earth’s orbit around the Sun are responsible for the comings and goings of the ice ages. But the warming we’ve seen over the last few decades is too rapid to be linked to changes in Earth’s orbit, and too large to be caused by solar activity.
Answer:
Option-C
Explanation:
Action potential refers to the generation of electrical activity due to the influx and efflux of ions in the cell.
The cell which transmits the action potential is known as the neuron and the neuron maintains the membrane potential at -70 mv. The influx of sodium ions causes depolarization when it crosses the threshold value.
The generated action potential now travels in the neuron through its long tubular structure called an axon. The axon transmits the signal from the cell body towards the axon terminal and thus is known as the down the axon.
Thus, Option-C is the correct answer.
