DNA is semiconservative because during replication, it separates into two strands. It then recreates the opposite strand on each of the original strands to form two new identical strands of DNA. It's not conservative because it does not recreate a whole new strand off of one whole original strand.
Well the area would not be able to fix itself as it can’t grow new skin cells without the process of mitosis, however it may still form a scab due to the platelets in the blood which help the blood to clot to prevent bleeding.
The answer is reproductive isolation. This ensures that there is no viable reproduction between
different species or subspecies. Even if reproduction
between species leads to conception, the embryo may not be able to survive to maturity or will be sterile. This ensures that
species remain integral by restricting gene flow.
I believe the correct answer is natural selection.
Natural competition and the fight for “survival of the fittest” is what pushes diversity the most.
