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.

I think the correct answer from the choices listed above is option B. The phase change that is an endothermic change would be vaporization. This includes melting and sublimation. Hope this answers the question. Have a nice day.

mote1985 [20]

Answer: The correct answer to the question is option 2

If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.

Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.

Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.

Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.

This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.

Smooth muscles depolarize as a result of a transmembrane current of ________. smooth muscles depolarize as a result of a transme
Oksana_A [137]
Smooth muscles depolarize as a result of a transmembrane current of Calcium ions.                                                                                                                       When an action potential depolarizes the muscle cell membrane, it also travels into the body of the cell via the t-tubules. Unlike skeletal muscle, smooth muscle is dependent in two sources of calcium in order to intiate contraction. These two sources are calcium sequestered in the S.R. of the smooth muscle cell.

Explain why it would be a problem if an organism's very first stem cells were copied and multiplied like usual, but they didn't
Allisa [31]

Answer:

If they didn't differentiate then the stem cells would stay the same type and if it somehow kept multiplying then they would just be a massive blob with no actual form or way of functioning.
