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.

I believe the correct term to fill in the blank would be digestive. Four functions of the digestive tract include ingestion, digestion, absorption, and elimination.The digestive tract group of organs that works together to convert the food taken in into energy and nutrients needed by the body.
Genetics combines Dna, technology, and agriculture
Each population is characterized by a certain percentage of asexual and sexual reproduction. The percentage of asexual reproduction ranges between 0% (complete sexual reproduction) and 100% (all the females reproduce by gynogenesis).
Answer:
Option (b).
Explanation:
Aposymbiotic may be defined as the type of biological interaction in which the organism lives in association with each other but lives apart from one another.
P. bursaria's requires the light for their growth and metabolism. The prey acts as the food source for the P. bursaria's. Hence, abundant amount of the prey and the abundant amount of light is favorable for the growth of the organism P. bursaria's.
Thus, the correct answer is option (b).
