Aresearcher wants to investigate the effect of patients' body position on blood pressure. the study would most likely be of which type?

The study would most likely be a QUANTITATIVE RESEARCH STUDY.
A quantitative research study is one that involves numeric measurements. The numeric measurement in the question given above is the value of the blood pressure which the researcher has to measure in the course of the research.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
