Answer: A change in allele frequencies caused by random events
Explanation :<u>Genetic drift refers to a process which occur due to sampling error from preceding generations that lead to a change in allele frequency by chance alone within a population.</u> It is a random process which leads to large significant changes within a population over a short period of time. The rapid changes are due to increasing inbreeding coefficient s and homozygosity from the removal of alleles.
It is peculiar to a population which is synonymous with regular cycle of extinction and recolonization. Therefore, together with evolution, mutation and migration, <u>it is one of the driving mechanism of EVOLUTION.</u>
It is caused by;
Static or recurring small population sizes,
"Bottlenecks” form of population, that is drastic reduction in population size;
Repopulation from a small number of individual-FOUNDER EVENTS.
<u>Measurements of Genetic Drift
</u>
The magnitude of genetic drift within a population depends on the effective population size for the population.This is represented as Ne. It is a theoretical number use to quantify the number of genetically distinct individuals that contribute gametes
Answer: Breach of confidentiality among focus group participants.
Explanation:
The research subjects or participants should assured with the fact that non of their personal information used for the purpose of research will leak out it will be confidential.
It is mentioned that specific clients of therapists will not be discussed about the purpose of research this is likely to reveal the purpose and requirement of research to them as the selected participant group will be asked for opinion.

Answer:
it is an obligate (or strict) aerobe
Explanation:
By whether an organism requires oxygen or not for respiration. We can classify it as either aerobic or anaerobic.
Aerobic organisms require oxygen and anaerobic do not.
For aerobes, it can be facultative or obligate. Facaltative aerobes require oxygen but they can however switch to fermentation when oxygen is not available.
Obligate aerobes are aerobes require oxygen for cellular metabolism.
In the test the dextrose tube remained yellow because fermentation had not taken place.
Therefore we can conclude the sample contained an obligate aerobe which was catalase positive since it produces bubbles when Hydrogen peroxide was added.
Answer: most similar to the frog the skin cell came from
Explanation:
I just took the test
