Diffusion- spreading particles (ex: angel of perfume spreading throughout the room)
Active transport- movement of ions from a low concentration to a higher concentration.
Osmosis- movement of partials through a semi-permeable membrane from a less concentrated solution to a higher one.
Greenhouse gases trap heat within the earth’s atmosphere, contributing to a gradual but persistent global warming pattern.
Answer:
The relationship between environment, variation and selection lay the foundation for natural selection and evolution.
Genetic variations are present among species due to number of reasons like recombination or crossing over during meiosis, mutations, random fertilization etc. These factors bring changes among the members of a species. Some of the species become better adapted to survive in a particular environment whereas some are not better adapted and become extinct over a period of time. The environment selects the organisms that are best adapted to survive and hence lead to variations.
They can make food, help keep the environment clean, and make medicines.
