Explanation:
<em>Mechanical- </em>Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.
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.
Answer:The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.
