An organism is a living entity that is defined by the presence of cells, which are the basic structural unit of life.

Organisms have the ability to respond to external stimuli, perform metabolic activities and exhibit a internal state of equilibrium (homeostasis).

Organisms can be composed of single cells (e.g., bacteria, protists) or many cells (e.g., plants and animals).

In conclusion, the Unit 'Understanding organisms' is not found here, but an organism is a biological system composed of cells.

In summary, the melting of polar ice caps effects would result in sea levels rising around 220 feet or more worldwide.

This will lead to destruction of lives, houses and properties due to water submersion.

This is why many say that humans, as well as animals, are sex-driven, and that in growing up, their sexual hormones will also become bigger (until it reaches its peak somewhere around early middle-age). Without this mentality, the group will always die out. Their next mentality is similar, to survive. This mentality essentially is just adding more steps to the first one, to survive long enough to reproduce and continue the race.
