Answer:
most likely the water was evaporated by the sun
Explanation: Evaporation is the process in the water cycle when water particles heat up and turn from a liquid into a gas.
Answer:
Radiometric dating methods
Explanation:
Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology. Absolute dating can be determined by using properties of the atoms that make up materials.
The most common method of absolute dating uses by geologists is radiometric dating methods which is based on the natural radioactive decay of certain elements such as potassium and carbon found in the rocks. By comparing the ratio of parent isotope with a known half-life to daughter product in the rock, the age of the rock can be determined.
The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.

The difference is that thymine is replaced by Uralic in mRNA.
Answer: Option D.
Cyclins are proteins that regulate the cell cycle at molecular level.
Explanation:
Cell cycle refers to series of activities that take place in the cell leading to replication of DNA and division of cytoplasm to give two daughter cells. Cell cycle are regulated by a set of proteins called cyclins.
Cyclins are group of proteins the bind and activates cycling dependent kinases enzymes in order to control cell progression through the cell cycle.
