B. essential
We cannot store up amino acids on our body, but we can have amino acids through consumption of food. These amino acids of which the body cannot make is called as essential amino acids.
The correct answers are:
- Porosity;
- Moisture;
- Temperature;
The weathering is a process that manages to break up the rocks into smaller pieces. This process and its effectiveness and intensity are dependent on multiple factors.
The porosity of the rock can result in a very quick process of weathering. The reason for that is that the water will be able to get inside the rock, thus reacting chemically, but also if the temperatures are very low and it freezes, it will create a pressure inside the rock that will result in cracking.
The moisture is also important factor because the more water vapor there is in the air, the more the chemical reaction with the rocks.
The temperature is very importation because it can affect the rock with both very high and very low temperatures, to widen it little and than to tighten it little, which will eventually cause the rock to break up.

Idk but you can ask google and I'm sure they will tell you
If the prefix endo- is Greek for within, and the "plasm" refers to the body of the cell, you can conclude that: The ER actually helps the attached robosomes make proteins. When these new proteins leave the ER (and they do) they move to another/different organelle.
