Answer:
C. They speed up the replication process.
Explanation:
A lot of ligma.............
Answer:
Billions
Explanation:
"Then each of these strands can be used to create two new copies, and so on, and so on. The cycle of denaturing and synthesizing new DNA is repeated as many as 30 or 40 times, leading to more than one billion exact copies of the original DNA segment."
<span>C; Reproductive isolation must occur before the formation of a new species.</span>
Answer is Meiosis.
Meiosis is the process by which most eukaryotic organisms form sex cells or gametes. During prophase of meiosis I, the homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement. The exchange of chromosome segment between non-sisters chromatids forms new combination of genes on a chromosome can lead to new traits in offspring. The process helps increase the genetic diversity of a species.
