- 7What is natural selection?The process by wich individuals are is better adapted to their environment and are more likely to survive and reproduce.
- 8How does natural selection led to evolution?Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring.

4. The universal genetic code - 12What is geographic isolation?A population of animals, plants, or other organisms that are separated from exchanging genetic material with other organisms of the same species.
- 13How can a geographic isolation lead to the creation of a new species?The organism has to adapt to their new environment and evolve.
- 14What is a branching tree (in relation to the classification of organisms?A diagram shows how scientists think different groups of organisms are related.
