Answer:
fire
landslide
avalanche
Explanation:
Fire, landslides, and avalanches are the examples of rapid environmental changes because they are able to destroy or affect the structure of living organism in a particular area. For example, fires can destroy all forms of life within days. A recent event of wildfire in Austria killed more than 1 billion of animals. Similarly, landslides and avalanche are geological calamities that are caused by the movement of a large mass of rock debris or snow moving downhill. The living organisms living there would be killed and this process can diminsh many forms of life (multicellular eukaryotes) rapidly.
On the other hand, (ecological) succession is a very slow process that results into change or disappearance of living organisms or particular species or ecological community in an area. This process can take place over decadaes, thousands or million of years. It can also lead to the species extinction as well.

I'm sorry I know only these 2 :)
The process of cloning effectively involves taking a cell from your body and turning it back into an embryo. The embryo would then either develop into a human being as has been proposed by various scientists around the world and which is currently banned, or it would be turned into a stem cell.
The main function of the smooth ER is to make hormones and lipids.
When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.
Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.
Hope this helped, even if it helped a tiny bit. :)
