Yes, it is true that evolution is a theory, which is a well substantiated explanation for observable facts.
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.
Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.
Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or rare within a population.
The evolutionary pressures that determine whether a characteristic would be common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms and molecules.

Explanation:
Thank you!
Answer:
A half filled orbital is LESS LIKELY to be reactive than a fully filled orbital
Explanation: A fully filled orbital has the electronic configuration of a noble gas. That is, unreactive.
The quantum states of these orbitals(fully filled) are stable because the electrons in the sub shell are fully filled which makes it difficult for it to loose and gain electron unlike a half filled which is much more easier. It will take more energy for ionization to take place making it(fully filled) more stable.
Without the choices, my best guess is absolute dating
Your answer should be Excretion.
