Explain how one can become infected with HIV​

Contact between broken skin, wounds, or mucous membranes and HIV-infected blood or blood-contaminated body fluids. Deep, open-mouth kissing if both partners have sores or bleeding gums and blood from the HIV-positive partner gets into the bloodstream of the HIV-negative partner. HIV is not spread through saliva.

please mark me as brainliest

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.

i am going to guess that it is co2.
