Why HIV virus not spread by mosquito

Biology
1 answer:
muminat4 years ago
3 0
Mosquitoes have a 6-tube system in their "snout". It's a big big needle with 6 parts to it. 4 of those parts are used to pierce the skin of the human. The other 2 parts are 2 tubes. One of those tubes sends saliva from the mosquito down into the human. The other sends blood up from the human into the mosquito.
Now, unlike some viruses (like dengue and Zikka), HIV cannot replicate inside a mosquito. HIV replicates inside human T-cells...there aren't any of those inside a mosquito gut. Eventually the HIV is destroyed and never makes it to the saliva of the mosquito - so the mosquito can never infect a human with HIV.

What does the 4th amendment protect against
dangina [55]

Fourth Amendment case law deals with three main issues: what government activities are "searches" and "seizures," what constitutes probable cause to conduct searches and seizures, and how violations of Fourth Amendment rights should be addressed. Early court decisions limited the amendment's scope to physical intrusion of property or persons, but with Katz v. United States (1967), the Supreme Court held that its protections extend to intrusions on the privacy of individuals as well as to physical locations. A warrant is needed for most search and seizure activities, but the Court has carved out a series of exceptions for consent searches, motor vehicle searches, evidence in plain view, exigent circumstances, border searches, and other situations.

almond37 [142]

The limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.

<h3>What is population dynamics?</h3>

Population dynamics is the part of ecology that studies the variations in the occurrence of individuals of the same species (population) and seeks to define the cause of these variations.

Example: with the hunting of alligators, there is an increase in the population of piranhas, thus resulting in a variation of occurrence.

With this information, we can conclude that the limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.

Testosterone oxi-reductase is a liver enzyme that regulates testosterone levels in alligators. one study compared testosterone o
Reil [10]

Explanation:

Environmental contamination reduces total testosterone oxido-reductase activity in females.- <u>True</u>

Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions- like the breakdown of large polysaccharides by amylase. Here, the enzyme testosterone oxi-reductase facilitates the of testosterone to the androgen DHT. Enzyme specificity is affected by pH, temperature and the presence of inhibitors.

In temperatures beyond its optimal range, these may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost. Testosterone would no longer be able to bind to the active site, and thus would not be converted.
