Answer:

The correct answer is: common ancestor

Explanation:

Hello! Let's solve this!

According to the evolution of living beings, we all have an ancestor.

Depending on the branch in which the living being is, it unites with the ancestor of another.

Two different branches that never join, do not have a common ancestor. In this case, they have a characteristic that unites them, so whales and pythons have a common ancestor.

The correct answer is: common ancestor

Is everyone’s heart biologically the same
WINSTONCH [101]
Yes and no. Everyone's heart works the same way, is made of the same type of tissue and is located in the same part of the body. However, there are people with diseases who have hearts that are in worse condition and may look different. For example, people with coronary artery disease experience plaque build up in their coronary arteries, which causes a reduction of blood flow to the heart, and in order to treat this they may get a bypass surgery in which another blood vessel from somewhere else in the body, would be used to bypass the blocked blood vessel. In this case the anatomy of that person's heart would be slightly different.

C3 fracture resulting in loss of sensation and inability to move arms and legs is known as what type of paralysis?
adell [148]

Answer:

The correct answer is quadriplegia.

Explanation:

The paralysis of both the legs and arms has been known as quadriplegia. The main reason for quadriplegia is the injury to the spinal cord, however, other conditions like strokes and cerebral palsy can also result in similar paralysis. The degree of damage depends upon the part of the spinal cord injured and the amount of destruction done.  

With the injury to the spinal cord, the brain loses the tendency to communicate with it and so the movement and sensation get impaired. Quadriplegia takes place when the region of the neck of the spinal cord gets injured like a C3 fracture. An extreme spinal cord injury may obstruct the process of breathing and hampers the movement of limbs.  

An individual with complete quadriplegia loses the tendency to move any part of the body underneath the neck, even some are not able to move their neck.
