Paleontologists are scientists that use fossil records to study the history of life on earth. They use known evidence/fossils such as bones, prints (on land or sea), dead remains to determine evidence and history of past life on earth.
Some of there observations include the use of comparative anatomy to determine possible evolution. They also use carbon dating to determine approximately how long a fossil/bone has been in existence.
The answer is C, Mercury.
Neptune and Uranus have extremely thick atmospheres, and Mars has an atmosphere that is made mostly of carbon dioxide, but Mercury doesn't have atmosphere at all.

The frequency of a wave represents the number of wavelengths that pass a specific point per second. The unit for frequency is hertz (Hz). A wave's period is the time for one wavelength to pass a specific point. The wavelength of a wave is the distance between two successive crests or troughs.

Answer:
Mitosis is a necessary step in repairing cuts on the skin.
Explanation:
When the portion of tissue cracks, then there are cells wasted. So, mitosis will generate tones of fresh cells in periods to fill the break and secure the tissue greater again. This guarantees that the tissue is back to health and can perform accurately. It's like wound healing. A necessary goal of mitosis is to replenish dead or destroyed cells like skin cells that are continually being shed.
