I don’t really understand this question can you go more into detail
Answer:
(B) The organism lives and replicates despite protease and DNase treatment, but the organism dies when treated with RNase.
Explanation:
DNA is the genetic material in present day organisms while some of the proteins serve as enzymes and catalyze the metabolic reactions.
An organism having RNA with the ability to serve as genetic material would not require DNA to survive. Likewise, if RNA molecules in these organisms also serve as the enzyme, proteins would not be required for survival.
Therefore, when treated with DNase and protease that digest the DNA and proteins respectively, these organisms would be able to survive. However, treatment with RNase enzymes that digest the RNA would kill them as RNA was their biocatalyst and genetic material.

Answer:
The answer is type A
Explanation:My explanation is I dont know
Answer: Meiosis produces the sex cells, that is the gametes (sperm cells and eggs) that unite to form a zygote. Meiosis ensures that the gametes have have haploid chromosomes so that the resulting zygote from their fusion will have diploid chromosomes.
Explanation: Meiosis is a type of cell division in which a cell divides twice to produce four daughter cells each with the half the number of chromosomes as the parent cell. Without meiosis new gametes are not produced. Meiosis ensures that the chromosomes are evenly distributed among the daughter cells and that each daughter cell contains 23 chromosomes. A sperm cell with 23 chromosomes fuses with an egg with 23 chromosomes to form a zygote with 46 chromosomes. If meiosis does not occur, gametes with haploid chromosomes will not be produced, and if the gametes have diploid chromosomes because meiosis does not occur, sexual reproduction will be a disaster because when two diploid gametes fuse the resulting zygote with be abnormal.
