Ierofanga [76]

Answer:

For this receptor, the stimulus begins with an explosion of action potentials.

that would be the correct option.

Explanation:

A tonic receptor is one that is activated when the action potentials were maintained over time and during the signaling of the receptor.

Tone receptors require continuous stimulation over a period of time to trigger a response and deliver it to the central nervous system.

It keeps the nervous system constantly active in the environment that surrounds it.

They are slowly adaptable, an example of these receptors are the merkel and ruffini receptors.

Lubov Fominskaja [6]

Answer:

Option (3).

Explanation:

Mark recapture method is used for the estimation of population size of an area. The individuals are identified by  some mark on them. The formula of mark recapture method is

N = M * C/ R

Here, N is the number of the individuals, M is the individuals are marked and captured, C is the individual captured again with mark or non mark and R is recaptured marked individual.

The individual with 200 population, 20 are marked for the first time represent the large population size.

Thus, the correct answer is option (3).

According to the passage, which of the following topics of study was the most crucial to his final analysis?
TEA [102]

Answer: The study of plant varieties.

Explanation:

This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.

Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.

He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.
