I think it is A,B, C and D. I know for sure that it is not E. Let me know if I was right
Answer:
heyooooo!!!!!!
Hydrogen ions play a central role in the lives of cells. For example, changes in hydrogen ion concentration are intimately tied to the charge of side chains in proteins. This charge state, in turn, affects the activity of enzymes as well as their folding and even localization. Further, the famed ATP synthases that churn out the ATPs that power many cellular processes are driven by gradients in hydrogen ions across membranes.
hope this helps!!

Answer:
B.chickens are more closely related to ducks than they are to humans.
Explanation:
Amino acids are coded for by codons.
Codons are sequence of nucleotide bases from mRNA.
mRNA are synthesized using DNA templates.
Therefore, the more similar the amino acid sequence of two organisms, the more genetically related the organisms are.
<em>Chickens and ducks had amino acid sequence of 3 while chickens and humans had 13. It thus means that chickens and ducks are more related as compared to chickens and humans.</em>
The correct option is B.
Answer:
Endospores may be defined as the tough, dormant and the non reproductive structures formed by bacteria and they are not true spores. This is a dormant phase occurs in unfavorable environmental condition.
The endospore formulation starts when bacteria detect the unfavorable conditions. This process takes 8 hours to complete. The spore sptum forms between the cells rests. The plasma membrane pinches off and leaves the double membrane around DNA and forms forespore. The peptidoglycan forms around the forespore, then endospore formed is dehydrated and allow to mature before they are released from the mother cell.
