Damage to sensory receptor cells would most likely result in ________. I. confusion of visual and auditory input II. inaccurate
MatroZZZ [7]

Answer:

The correct answer is: None of the above. The accurate answer is: Problem or inability in detecting the sensory information.

Explanation:

  • Sensory receptor cells form the part of the sensory epithelial layer that are present in the form of a lining in all sensory organs.
  • These sensory cells possess some specialised receptor molecules, usually on the surface of the cells, that can sense different types of sensory signals like light, in case of eyes, smell is case of nose, taste in case of tongue and sound in case of ears.
  • Any damage caused to these cells will adversely affect their capability to perceive or receive or detect the sensory signals.
  • Option I is incorrect because sensory cells are not only present in the eyes and ears but also in nose, tongue, skin. The activity of the sensory cells of one organ is independent of the activity of sensory cells of other organs hence, damage to the sensory cells of one organ will not create any confusion in different sensory inputs.
  • Option II is incorrect because integration of all the sensory impulses occur in the brain after the impulse has been received and detected by multiple sensory receptor cells and send to the brain through the sensory neurons.

As the sample size increases, the t-distribution becomes more similar to the ________ distribution. a. normal b. binomial c. chi
kvv77 [185]

As the sample size increases, the t-distribution becomes more similar to the <u>normal</u> distribution.

<u>Option:</u> A

<u>Explanation:</u>

Student t-distribution is any member of a group or family of constant probability distributions that emerge in circumstances where the sample size is limited and the standard deviation of the population is unspecified when calculating the mean of a naturally distributed population.

The z-distribution implies you are conscious of the normal population deviation (never in case) when used for sample means. The t-distribution is focused on using the standard sample deviation as an approximation of the standard deviation in population.

The theory of what tells us that favorable traits will become common in a population over time
Radda [10]
Natural selection! In the theory of natural selection, those with less beneficial traits won't live to reproduce, but those with beneficial traits will be able to reproduce and pass on those traits to their offspring, which significantly increases the frequency of those beneficial traits.
