The correct answer would be D, because the ending result for mitosis is 2 diploid cells, meaning the number chromosomes are the same. While in meiosis, the ending result is 4 haploid cells. Because the cell was divided twice, this means that each daughter cell has half of the number of chromosomes.
Explanation:
The lipstick from the crime would be crushed and dissolved in an appropriate liquid solvent. The lipstick would then be placed in one of the ink spots on the starting / base line of the paper. Another spot would be created for the lipstick with which it is being compared with.
The paper chromatogram would then be placed vertically on a solvent that acts as the mobile phase. After some time, when the solvent reaches the solvent front of the paper chromatography, by capillary action, the chromatogram can be removed and left to dry.
Bands will have appeared on the chromatography paper formed from the different components of the lipstick. The bands of the lipstick from the crime scene and that with which it is being compared to are observed. If the bands are all aligned, horizontally, then this means it is a complete match. The lipstick must have been the same used at the crime scene.

The Precambrian era envelopes the major bulk of the history of the Earth, beginning from the creation of the planet approx 4.5 billion years ago and terminating with the origination of composite, multicelled forms of life approximately 4 billion years after.
The Precambrian refers to the earliest of the geologic ages that are signified by the distinct layers of sedimentary rock. The Earth was about more than six hundred million years old when life started. The planet had cooled down from its native molten state, creating a solid crust and oceans formed by water vapor in the atmosphere.
At about three billion years ago, the atmosphere of the Earth was virtually devoid of oxygen. At approximately 2.4 billion years ago, oxygen was discharged from the seas as a waste product of photosynthesis by cyanobacteria. The levels of the gas slowly raised, attaining about 1 percent around two billion years ago.
Approximately 800 million years ago, the levels of oxygen attained about 21 percent and started to breathe life into more composite species. The oxygen-rich ozone layer was also created, protecting the surface of the Earth from the harmful solar radiation.
