Answer:
The DNA polymerase is the enzyme which copies in the direction of 5' to 3' in the leading strand and in case of lagging stand it is opposite. that is from the 3' to 5'.
Replication in the 3' to 5' takes place in the fragments which is laid by the Okazaki fragments. These small fragments are kept together by the help of the enzyme known as DNA Ligase. So, called as discontinues
Incase of leading strand, the strand is in the same direction of the for the process of replication (5' to 3'). So it is continuous.
Hence, the whole process is a combination of continuous and discontinuous DNA synthesis.

Answer:
eight haploid
Explanation:
Megaspore (macrospore) is a type of spore present in heterosporous (production of spores of two different sizes and sexes) plants.
During megagametogenesis, a single nucleus undergoes mitosis three times producing an eight-nucleate.
Answer: changed by molecular oxygen
Explanation:
Biologically induced molecular oxygen (dioxygen, O2) started to accumulate in Earth's atmosphere and changed Earth's atmosphere from a weakly reducing atmosphere to an oxidizing atmosphere.
