Means they are related through a common distant ancestor. This shows that these structures (morphology) are homologous. They all have 7 neck (cervical) vertebrae, but giraffes cervical vertebrae are elongated compared to that of humans due to their adaptation as browsers .

which autonomic system conserves energy by returning the body to a normal activity level through a lowered heart rate and blood
SVEN [57.7K]
The parasympathetic nervous system <span>conserves energy as it slows down heart rate, increases intestinal and glandular activity, and relaxes the sphincter muscles of the gastrointestinal tract. It gets the nickname "rest and digest" for doing exactly so. Typically most active when sleeping, however is also the explanation for post-prandial fatigue, or being tired after eating (especially a large meal).</span>

How is a brain injury classified?
faltersainse [42]

Answer:

As an injury of the central nervous system.

Explanation:

Peripheral nervous system is the nervous system outside the brain and spinal cord. The central nervous system consists of the brain and spinal cord. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, and more. The somatic nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. Therefore, central nervous system is your answer!

Differentiate between persistent and latent animal virus infections.
lana66690 [7]

Answer:

The difference between both infections is that viral infections where the virus is latent, this virus once infected is protected in the nerves of the animal organism, as for example in humans the herpes family viruses (HSV1) are housed in ganglionic terminals such as the trigeminal ganglion or the V cranial nerve, so that in a situation of immunodepression, reinfect the individual again, causing him to be unable to remove the virus from his body.

On the other hand, persistent infections diseases are the threats that persist because the microorganism cannot be eliminated, either because it is very complex, or the cure does not exist, or the correct treatment is not carried out. Furthermore, it is necessary to consider that some microorganisms mutate becoming resistant to these drugs and thus persist longer in the body until they are eliminated.

Explanation:

In short, latency refers to the fact that the individual lives with the virus for life, and persistence is that it is possible to eliminate it over a long period of time since the infectious microorganism is considered very difficult.

Who is studying animals in the wild considered to be somewhat experimentally out of control
KIM [24]

Studying animals in the wild is considered somewhat experimentally out of control because of several reasons.  

<u>Explanation:</u>

Study of wild animals can be done using several methods but none will be as effective as studying captivated animals. Using stationary cameras is a method to observe animals in the wild. The stationary nature of the camera makes it necessary for the animals to appear within the field of the camera.

This is difficult in places of low animal density. In addition to that placing camera at a longer distance to watch a larger area decreases the resolution of the images. When it comes to shallow water systems, the field imagery used to track the aquatic species frequently gets affected by issues like sun flicker.  

Unmanned aerial vehicles can also be used to track and study animals in the wild. This is good alternative but filming through dense canopies or turbid water is a limitation. Bio loggers can also be used for animal tracking but it is limited by weight since it has to be carried by animals.
