Answer:
<h2>Agree
</h2>
Explanation:
1. Through mitosis, Parental cell divide into two daughter cells with same number of chromosomes.
While meiosis produce 4 daughter cell from a single cell with half the number of chromosomes as compared to parental cell.
2.Meiosis have two cycles , i) meiosis I and ii) meiosis II.
3. In meiosis I, chromosomes first go replication and become double, then cell inter into meiosis I then into meiosis II and finally produce four haploid daughter cells. It is the first step (meiosis I) that generates genetic diversity. During prophase I of meiosis I (meiosis) homologous chromosomes pair and form synapses, a special step of meiosis, which is the main reason of causing diversity.
4. There is crossing over which produce genetic diversity between gametes.
The beginning of the Cambrian Period is marked by the evolution of hard body parts such as calcium carbonate shells. ... These body parts fossilize more easily than soft tissues, and thus the fossil record becomes much more complete after their appearance.

Symptomatology and transmission
The clinical manifestations of acute HBV infection are age dependent. Infants, young children (younger than 10 years of age), and immunosuppressed adults with newly acquired HBV infection are usually asymptomatic. [2] Older children and adults are symptomatic in 30%–50% of infections
Answer:
No
Explanation:
I think No. because matter can neither be created nor destroyed...chemical change cannot alter the number of atoms in a given reaction. The atoms can only rearrange so that it can yield a new molecule/compound but the number of atoms should stay the same.
