Answer:
Answer is C. Damage to C3, C4 or C5.
Explanation:
C1 - C7 are used to represent the number of vertebrae found at the cervical region of the vertebrae canal or column. The vertebrae column comprises off various vertebrae that protect the spinal cord,which starts from the neck region to the tail region.

Answer:
The answer is letter B, keep him warm and ventilate with BVM.
Explanation:
In order to know more about the answer, let's check out the meaning of "Premature Baby" first.
Premature Baby- a baby born through premature birth <em>(fewer than 37 weeks).</em> Babies are normally born at the usual <em>40 weeks.</em> Health problems may occur with premature babies, thus it is very important to monitor them.
In the situation above, the premature baby's heart rate is only 90 beats/min. <em>A resting heart rate for a newborn infant is 130-150 beats per minute. </em>This means that the baby above has a slow heart rate. In order to increase the hear rate, it is important to keep the baby warm and to ventilate with a "Bag Valve Mask" (BVM). <u><em>An increase in internal temperature increases the heart rate. Increasing ventilation will also help increase the heart rate. </em></u>
<u><em>Remember: </em></u>Inhalation increases the heart rate.
Answer:
The correct option is B) Their offspring cannot breed.
Explanation:
Organisms belonging to the same species require the ability to breed and produce fertile offsprings. If two organisms breed to produce infertile offsprings, then they are not considered to belong in the same species. Infertile offsprings do not have the capability to reproduce. The breeding between a horse and a zebra produces zorse, which is sterile. This depicts that both the zebra and horse belong to different species as they cannot produce a fertile offspring.
