These are all disadvantages but I would say that A and D or A and B are the most serious ones.
<span>Prior to drawing blood for a blood donation, the nurse will clean the arm with a betadine solution. this form of antimicrobial control is called ANTISEPSIS.
Antisepsis is the practice of using antiseptics or antimicrobial substances to reduce or eliminate the possibility of infection by applying it to living tissue or skin.
Betadine solution is an antiseptic solution.</span>
In eukaryotes, the DNA strands are linear, and DNA polymerase can't replicate the very ends of the DNA strands! These ends are "protected" by repeated sequences called "telomeres." Either the chromosome gets shorter with each replication, or else a special enzyme-nucleic acid complex called telomerase adds new telomeres to the ends. A prokaryotic chromosome is circular and thus does not have the problem of having ended.
<span>Eukaryotic DNA is wound around histones, coiled, and supercoiled -- to replicate it, there have to be unwinding mechanisms, and mechanisms to reduce the degree of coiling. In prokaryotes, the winding problem is much less, and there aren't any histones.</span>
The Answer is d.
Hope this helps:) Have yourself a great day:)
A scientific hypothesis must be testable and yield results. It must state the intended or predicted result of the experiment
