Answer:
It is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size.
The energy of moving matter is called kinetic energy. Scientists think that the particles of all matter are in constant motion. In other words, the particles of matter have kinetic energy. The theory that all matter consists of constantly moving particles is called the kinetic theory of matter.
- If particles do not have enough kinetic energy to overcome the force of attraction between them, matter exists as a solid.
- If particles have enough kinetic energy to partly overcome the force of attraction between them, matter exists as a liquid.
- If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a gas.
Abiotic are the non-living physical and chemical factors that can affect the ecosystem, such as amount of water, temperature, amount of sunlight, etc.
Biotic are the living organisms inside the ecosystem, and can include humans, animals, and plants.
