Answer:
A. Sexual Reproduction creates genetically different offspring.
Explanation:
Sexual Reproduction is created through 2 different opposite parties, in which the product takes around half of the genes from each individual parties. The traits that are shown are then decided on whether or not they are dominant or recessive or non-existent.
In a Asexual Reproduction, the reproductive capabilities of both parties are found inside one organism. The organism is able to produce both the sperm and egg, and therefore do not need a partner to reproduce. This means that the DNA inside the body is the only source for production, and that there will be very little variation in the DNA.

1. The right answer is in a discontinuous manner.
During DNA replication, the DNA polymerase synthesizes complementary DNA by mating on both strands, since the two strands are antiparallel, the replication is bidirectional, which means that one of the two strand is synthesized in a direction opposite to that of the direction of the enzyme, to do this, the DNA polymerase is obliged to synthesize DNA in the form of small fragments which are called Okazaki fragments, and its synthesized discontinuously (these fragments are not glued together by phosphodiester liasons, it is only after that another enzyme will intervene to ligate these fragments (DNA ligase).
