The speed of a nerve impulse in the human body is about 100 m/s. if you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (assume that you are approximately 2.00 m tall and that the nerve impulse travels at uniform speed.)

0.02 s takes the nerve impulse to travel to your brain.

Explanation:

We have an arythmetical equation that is proposed in the problem.

If the speed of a normal nerve impulse is 100 m per one second, how much will take the same impulse in go throught 2 meters, so it does 2 meters in X s.

After we have our equation formulated we need to find x

This is the way how we found that there is a time of 0.02 s that takes the nerve impulse to go from the toe to your brain if you are 2 meters tall.

i believe the answer would be b. hope it : )

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
