This should be of use here.
Answer: The correct answer is B) Vaporization.
A process is called endothermic when it absorbs energy from surrounding. In other words, if energy is consumed in any process then it is termed endothermic change. When any process releases energy in the surrounding then it is called exothermic process.
In vaporization, energy is absorbed by water molecules, which form vapors. Thus, it is an endothermic change.
On the contrary, in condensation, deposition, and freezing, the new bonds are being formed and thus energy is released in the surrounding. Therefore, they are exothermic process.
1.
The first prokaryotic cells (the less complex in its organization and with no organelles involved in membranes) evolved about 3.5 billion years ago. Therefore, the correct answer is D. 3.5 billion.
2.
Then, some prokaryotic cells evolved to use the sunlight to produce energy and release O2 into the atmosphere about 2.8 billion years ago. Therefore, the correct answer is C. 2.8 billion.
3.
After that, the prokaryotic cells evolved to cells with organelles bounded by membranes, and then the eukaryotic cells evolved about 2.5 billion years ago. Therefore, the correct answer is B. 2.1 billion.
4.
A long time after that, aproximately 650 million years, the first life composed of an organism with multiple cells evolved. Therefore, the correct answer is A. 650 million.
