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.
Two examples of a base other than those could be, borax, and lye.
Answer:
from the intermembrane space to the matrix
Explanation:
In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.
Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.
Weathering can be caused by rain,snow,heat,and as well as wind.
Answer:
The first line of defense involves skin.
