Number the steps from when a stimulus is received to when the body reacts. The stimulus is received by sensory receptors.

Motor neurons cause muscles to contract so the body can react to the stimulus.

The brain processes the information through interneurons.

Interneurons transfer response information to motor neurons.

Sensory neurons carry stimulus information to the brain or spinal cord

Explanation:

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
