Airida [17]
<h2>Axons </h2>

Explanation:

Axons cross from one side of the spinal cord to the other through the gray commisure

  • Each arm or extension of the gray matter in the spinal cord is referred to as a horn
  • Projecting towards the back of the spinal cord are the dorsal horns (or posterior horns)
  • Projecting towards the front are the ventral horns (or anterior horns)
  • In the thoracic and upper lumbar regions of the cord, an additional pair of side projections occur, which are called the lateral horns
  • A narrow band of gray matter known as the gray commissure stretches across of the center of the spinal cord and connects the two sets of horns
  • In the middle of the gray commissure is the central canal, which contains cerebral spinal fluid

A controlled experiment___. A. Includes one group for which the scientist controls all variables. B. Includes at least two group
notsponge [240]

Answer:

The correct answer is:

Includes at least two groups, one of which does not receive the experimental treatment. (B)

Explanation:

A controlled experiment is made up of at least two groups of participants (subjects). One group (the test group) receives the experimental treatment, which can be an intervention or a new drug to be tested etc, and the effect of the treatment on the subjects is measured, while the second group of similar subjects also known as the control group acts as a baseline and do not receive the treatment or intervention. They act as a baseline to ensure that the change observed in the treatment group was brought about as a result of the treatment.

<em>Note that repeating the experiment several times does not ensure accuracy of the result, rather it ensures reliability of the results hence option D is not correct</em>
