The human immunodeficiency virus (HIV) that causes the disease known as aids selectively infects helper T cells (CD4+).
This retrovirus also infects macrophages and dendritic cells. When CD4+ T cell numbers decrease below a critical level (due to the killing of this cells with different mechanisms), cell-mediated immunity is lost. As a result, the body becomes progressively more susceptible to infections, leading to the development of AIDS.
<span> HIV can be transmitted only via body fluids like blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk, which means that people usually get or transmit HIV through sexual behaviours and use of the needle. For HIV infection, these fluids must come in direct contact with a mucous membrane or damaged tissue. Another way is to be directly injected into the bloodstream (from a needle for example).</span>

Well I think I might know this since I was born and grew up in WI, but don't be 100% dependent with my answer because I'm only in 7th grade and I am doing high school stuff. Well my guess is the proportion of the genes is 1/2 because when a offspring is produced the genes are split from each parent rather its a human baby, a mammal, a fish, a reptile, a insect, or a plant. Although, I don't know what f1 means except for it being a control on the computer lol. But like I said I'm only in 7th grade so I don't know everything but I'm smarter than a average 7th grader.
Hope this helps! (it probably wont though)
Answer:
This new food is a carbohydrate
Explanation:
<em>Carbohydrates (also known as saccharide) general formula is CH2On, this means they are molecules that only contain carbon (C), hydrogen (H) and oxygen (O). </em>In the basic form, these sugars are known as monosaccharides, they can combine no form more complex sugars like disaccharide (2), oligosaccharides (2-10) or polysaccharides (>10).
Therefore we can conclude that this new food is a carbohydrate.
I hope you find this information useful and interesting! Good luck!
