Answer:
The type of sampling used in Jankowski's study of gangs is Option D. Stratified sampling.
Explanation:
With stratified sampling, the researcher will partition the population into different groups, usually based on some characteristic that is common to that group. In this case, it was the different kinds of gang membership. Then, the researcher will take a sample of people within each specific group using another sampling method like simple random sampling for instance. The groups that are used in stratified sampling are called strata. Another example would be a national survey that is divided into strata of the different major ethnic groups that comprise the national population.

Answer:
A. Genetic predispositions.
Explanation:
It is known as a genetic predisposition to the way in which the genetic phenotype of an organism influences an individual or a population. The phenotype is the genetic load that differs from one organism to another and that is usually modified by the environmental conditions to which the population is exposed.
In this case, Donna and Derek have phenotypes that react differently to sun exposure, which is why their skin burns to a greater or lesser intensity. It is very likely that Donna's ancestors came from a hot environment where they were frequently exposed to the sun, while Derek's ancestors were from a colder environment where there was less exposure to the sun.
The genetic phenotype can also define the probability that an individual or population has of having a disease or having certain physical characteristics.
