Human birth weights range very narrowly between 5.5 and 8.5 pounds. Babies much smaller than 5.5 lbs. suffer a higher mortality
Margarita [4]

Answer:

a.  Stabilizing selection

Explanation:

Babies lower than 5.5lbs would suffer from various disorder because of low birth weight as their body would not be able to compete as well they would have weak immune system and malnourishment. Whereas high birth weight carry the equally above risk as their body wont be able to cope up and organs become insensitive to various hormones. for the survival the birth weight should be within a median range so that it would be favorable for themselves and surroundings.

Stabilizing selection occurs when a population stabilizes on a particular trait value and genetic diversity decreases. As in this example, an average baby weight has to favour against extreme variation for it's better survival.

therefore, this is an example of stabilizing selection.

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.
