Please state the following :)
9 possible outcomes.
1. There are two coins being flipped.
Possibilities:
HH (two heads) HT (heads and tails) TT (two tails)
There are three sides to the spinner
Possibilities:
Side 1 Side 2 Side 3
Since there are 3 possibilities for each, multiply them together
So, 3*3 which equals 9 possibilities
Answer: A. In the electron transport chain, a series of reactions move electrons through carriers.
B. The products of the electron transport chain are H2O and either NAD or FAD.
E. The electron transport chain is a series of oxidation-reduction reactions that occur in the inner mitochondrial membrane.
Explanation:
the best suitable statement is it transfers energy stepwise from one compound to another, The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are transferred from one member of the transport chain to another in a series of redox reactions.
I believe the correct answer is: HIV is spread during unprotected sex or through contact with infected blood; it cannot be cured, but early treatment can minimize the long-term consequences.
<h2>Explanation:</h2>
Human Immunodeficiency Virus is a type of virus which causes an impairment of the immune system of the person making them susceptible to diseases such as tuberculosis, influenza and any other disease that can exploit this opportunity. It is spread by a person coming into direct contact with infected bodily fluids such as saliva during deep kissing, semen during intercourse, blood after an accident or even fluids when sharing needles and syringes for drug addicts. There is no cure but the current form of treatment slows down the virus to prevent some consequences.
<h2>Further Explanation:</h2>
The virus is enters the body through open wounds or surfaces such as the vagina or mouth where the skin is very thin and can tear. After penetrating the skin, it attaches to specific immune cells called CD8+ T-cells on points called receptors. It then enters the cell and replicates itself in the nucleus of the cell and as it goes out, it kills these immune cells making the person to have a weak immune system. The current drugs used called AntiRetroVirals (ARVs) such as the drug Zidovudin stops the virus from replicating thus reducing the total amount of virus in the body called the Viral Load. Some drugs target enzymes called proteases and reverse transcriptase that help the virus to replicate. This viral load is what is counted to estimate the total volume of HIV someone has in their body. Infected persons should use protection while having sex and also avoid sharing sharp objects to prevent transmission. They also need to take their medication to make them much more healthier in addition to taking proper balanced diets.

Answer: In a predator prey relationship, the predator kills and eats the prey. In a parasite/ host relationship, the parisite is feeding off the host, without killing it. If the host dies, the parasite will as well.
Explanation:
I hope that makes sense XD good luck
