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.
Answer:
The correct answer will be option-C.
Explanation:
The evolution of human species in which one species transformed into another species evolves by a mechanism known as anagenesis.
Anagenesis is the mechanism of evolution which transform one species into a different species within a lineage. This process is slow and takes time to form species, therefore, is also known as gradualism or phyletic transformation.
The<em> Homo sapiens</em> evolved from<em> Homo erectus </em>where<em> Homo sapiens </em>overwrites the ancestral species and caused the species to become extinct.
Thus, Option-C is the correct answer.

Answer:
1. Arsenic, benzene, formaldehyde, lead, and mercury are just a few of the more than 70 cancer-causing chemicals in cigarette smoke.
2.They work, for instance, to keep the airways clear of mucus and dirt, allowing us to breathe easily and without irritation. They also help propel sperm.
3.Spirometry measures how much air you can breathe in and out. It also measures how fast you can empty the air out of your lungs. Spirometry helps diagnose breathing problems such as asthma and COPD.
4.
Tar causes cancer of the lungs, mouth and throat.
