Answer:

Option-D

Explanation:

A reflex arc is the neuron pathway which is involved in producing the response to reflex action or the immediate response.

The reflex arc pathway involves the sensory neurons, interneurons and the motor neurons. Although the reflex arc pathway involves the brain later but in producing response the brain is not involved.

The stimuli are perceived by the spinal cord but not the brain therefore the selected option is correct.

Thus, option-D is correct.

Use the information below to answer the following question(s). In a survey, the rate of heavy smokers was reported as 270 per 10
Eddi Din [679]

The probability that neither of them is a heavy smoker is 0.53 or 53%

<h3>What is genetic probability?</h3>

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.

In this case:

Probability that selected one is heavy smoker is:

p=270/1000=0.27

Number of individuals selected  is 2 and We know that:

P(X=x)=nc_x(1-p)^{n-x}(p)^x

We need to prove that X=0:

P(X=0)=nc_0(1-0.27)^{2-0}(0.27)^0

P=0.5329
