Answer:
True
Explanation:
Meiosis is the kind of cell division that results in the production of daughter cells with each cell having half number of chromosomes as the parent cell. Meiosis is the cell division employed by reproductive cells to produce gametes/sex cells. Meiosis occurs in two stages i.e. Meiosis I and II. The chromosome number reduces by half in gametes in order to ensure that after fertilization of both male and female gamete, the resulting organism has the correct set of chromosomes. e.g diploid organism produces haploid gametes which fuses to produce a diploid organism again.
Mitosis is another type of cell division that results in identical daughter cells. They are identical in the sense that they possess the same number of chromosomes as the parent cell that divided. For example, a diploid cell undergoes mitosis to produce two diploid daughter cells.

Answer: Option A.
Polar ice cap in Antarctica.
Explanation:
Scientist drill ice cores from inside the polar ice cap in Antarctica to study variability of climate and differentiate that variability From global climate change. Each layer of the ice tells about weather and what the Earth was like when the first snow fell.
For example, Le grande says that as snow deposits into a growing glacier, the temperature of the air imprints on water molecules.
Icy layers hold particles,aerosols, sea salts, trace elements that were in the atmosphere before and they abide for thousands of years and provide evidence of past events.
