Trinna and Suzanne are identical twins who were the same length at birth. They were adopted by different families at birth and then reconnected in their early thirties. Trinna is two inches shorter and was a severely selective eater as a child. A researcher was conducting an investigation about twins separated at birth. What research method and explanation best fit this scenario?a. A longitudinal study, bc heredity is more important than enviroment
b. A case study, bc enviroment is more important than heredity
c. a case study, bc both heredity and enviroment are important
d. a longitudinal study, because enviroment is much less important in early childhood
e. A correlational study, bc parents' height levels have little correlation with children

Your question is poorly written, but as far as what was read the best thing would be a longitudinal study since you could see the evolution over time of the twins.

Explanation:

Longitudinal studies, unlike cross-sectional studies, are studies that analyze a factor in a population over time, thus analyzing the possible variables that occurred in those years, months or days. In simple words, the evolution over time is what a longitudinal study is based on (On the other hand, not a transversal one, since it would investigate a specific problem at a specific moment in time)

be confident on yourself. ignore such fools and move on ; )

well, it depends. it is natural to not fall asleep before 11: 00 p.m. teens need about 8-10 hours of sleep each night to function best.

enjoy your day!
