Antibiotic resistance happens naturally due to genetic mutation through random selection, however, genetic drift occurs on purpose and tests which genes are stronger and should continue to be passed on to future generations. In most cases, genetic drift is needed and antibiotic resistance isn’t.
1) symbiosis is a mutually beneficial relationship between two things.
2) the symbiosis in this example shows how the sea anemone provides the clown fish with protection and in return the clown fish helps the anemone by warding off any predators

Answer:
See explanation
Explanation:
According to the theory of evolution,species which are better adapted to their environment tend to survive and reproduce in a population passing on these favourable characteristics to their offsprings.
During sexual reproduction, genes can be arranged in new ways from chromosomal crossing over and recombination. This introduces new gene combinations(genotype) and ultimately variation in the population.
This variation may also lead to the observation of new phenotypes in the population.
