Answer:
Testing positive for HIV means a high chance of death and a good chance of lower reproduction rates. But some people are immune to HIV, which makes them more evolutionarily fit, likely to live longer, likely to reproduce more, which would increase the frequency of the immune allele in the population. Over time, this increase in frequency of the gene that causes immunity could spread across the human race and cause it to evolve.
 
        
             
        
        
        
Explanation:
A. Creativity
Creativity is a characteristic or trait in scientists or other answer seekers that allows them to think out of the box. It allows them to look through different perspectives to find new or other solutions to a problem.
 
        
                    
             
        
        
        
If a higher concentration of salt is placed outside of the cell membrane, the water will leave the cell to bond with it. The loss of water from this movement causes plant cells to shrink and wilt.
 
        
             
        
        
        
Isocitrate + NAD+ -> a-ketoglutarate + CO2 + H2
The amount of ATP produced from one molecule of glucose will decrease because NADH is no longer produced in the isocitrate dehydrogenase reaction. Without generation of this high energy electron carrier there will be less electrons from one molecule of glucose that are transferred to and through the electron transport chain. So there will be less protons (H+ ions) pumped into the intermembrane space. So there will be less of a H+ ion gradient across the inner mitochondrial membrane to drive the synthesis of ATP by ATP synthase. 
        
             
        
        
        
Answer:
Ribose
Explanation:
Ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.
