Why does DNA replication have to occur before cell division? Explain what would happen if it did not occur
SCORPION-xisa [38]

DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

The postpartum client and her husband are excited about their new baby. however, they are also concerned about getting pregnant
ololo11 [35]
The nurse should include in their discharge notes to the couple the different ways they may access to guarantee birth control.
They may continue to use barrier methods which are the most safe when it comes to not disturbing any hormonal balance or intervening with the milk. Condoms for men are usually the most easily accessed to.
Besides the barrier methods, there are also the hormonal methods. When breastfeeding these are not the most used methods. There is a special pill, progestin-only pill, that is the most appropriate because it doesn't affect milk supply when taken after 6 to 8 weeks after the birth. All hormonal methods should be taken always when counselled with the doctors.

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.

How does the carrying capacity of the ecosystem for the white footed mouse respond to the changes in the amount of parasites? Co
9966 [12]

Answer:

See the answer below

Explanation:

<em>The carrying capacity of the ecosystem for the white-footed mouse reduced in response to the changes in the amount of worm infected mice in the population.</em>

The carrying capacity of an ecosystem for a particular population of organisms is the maximum number of organisms the ecosystem can support based on the resources it has.

<u>The ideal carrying capacity of the ecosystem for the white-footed mouse oscillates between 36 to 40 in graph 1. The carrying capacity range reduced in graph 2 from 36 - 40 to 30 - 36 as a result of changes made to the number of mice infected with parasitic worms in the population of the animal. </u>

Thus, the introduction of more worm-infected mice into the population probably put more pressure on the ecosystem resources thereby reducing the carrying capacity.
