The answer is; the skeletal system and the nervous system
The skeletal system (muscle and bone) give you rigidity and enable your legs to support your weight. The muscles also act on the bone as a fulcrum allowing it possible for them to contract and make motion possible.
The nervous system is important in the coordination of movement. The brain is the center for locomotor action. This ensures you are able to place one foot in front of the other in sequence and moving your arm in concert.
It would be the first choice :)
Because when replicating DNA, this process is called semi-conservative
Hope this helps :)

In order to understand the totality of the interactions among the organisms in the biosphere, we need to at least understand <span>how the all genes function within organisms and </span>interact<span> with others organism and environment around it.
If we try to make this effort in a world where organisms will keep evolving and environment will keep changing like us, that tasks is impossible to finish.</span>
That would be 0%. An organism with a genotype of (ss) can only produce the s allele within their gametes. So the probability of their gametes containing an s allele would be 100%, while the S allele would be 0%.
