Answer:
A "chain reaction" is a reaction that promotes or spreads the reaction. PCR rapidly makes a bunch of copies of a specific DNA sample and can "promote" the increase the amount of DNA.

1
Explanation:
During meiosis, a diploid cell ultimately forms four haploid gametes that go on to take part in fertilization. Because they are haploid. that means they have one copy of all of the chromosomes and the genes contained within them.
First, the DNA is replicated, and then two cell divisions take place form the haploid gametes. So at first, there are two copies of each gene, creating four after the DNA is replicated.
After the first cell division (meiosis I) there are two cells with 2 copies of every gene. Then to form the haploid gamete, there is another cell division (meiosis II) creating 4 cells each containing one copy of every gene
Answer: Compounds which have carbon and hydrogen atoms in their structure or formula are known as organic compounds. For example, a molecule of is organic because it has carbon and hydrogen atom in its formula
Explanation:
Compounds which have carbon and hydrogen atoms in their structure or formula are known as organic compounds.
For example, a molecule of CH_{4} is organic because it has carbon and hydrogen atom in its formula.
Whereas atoms which do not contain carbon atom in their formula or structure are known as inorganic molecule. For example, NaCl is an inorganic molecule.
Thus, we can conclude that an organic molecule will always contain carbon and hydrogen.

The answer is A, as all the other answers are false.
