The nuclear envelope is perforated with pores to allow it to move in and out of the nucleus.
Every cell in the body has a nucleus, except for mature erythrocytes (red blood cells). While some cells contain more than one nucleus such as skeletal muscle and some other cells contain several nuclei.
The nuclear envelope surrounds the nucleus. i. e. largest organelle of the cell. It has a similar structure to that of
the plasma membrane. But the nuclear envelope contains tiny pores that allow a few substances to pass between it and outside the cytoplasm, i.e. the cell contents excluding the nucleus.
Therefore, the nuclear envelope is perforated with pores to allow it to move in and out of the nucleus.

Answer:
Water molecule is present in air these airborne water molecule are called water vapor, when the molecules are present in air they don't normally stick together as the space is too much.
Bill Nye took a giant bottle and covered it with a stopper and started pressurizing it with a pump to make the molecules come closer and become compressed also it increase the temperature even slightly and that warmth will cause the liquid stick with the smoke particles to go back to forming as vapor.
After that he removed the lid then the air inside the bottle is spread out and it will eventually cool also the kinetically energy is also reduced and that cooled air sticks with dust particle which now forms cloud.
This experiment shows how the clouds are formed and the science associated with it.
A cactus can survive in really dry, hot weather. They store water in their "trunk." Just think of where a cuctus lives. They live in a desert. A desert is dry, hot, and lots of sun. Cactus manage to survive in that enviroment.
