In this technological age, today's students are faced with on-line educational opportunities at both the high school and post-high school level. Many educators wonder how effective such on-line courses really are. Imagine you are an educator designing an on-line course. Before beginning, you decide to conduct a study about the effectiveness of on-line courses. Which research question would be MOST appropriate to guide your study? A) What are the strengths and weaknesses of on-line courses? B) How do students' grades compare in on-line versus traditional courses? C) How do standardized exam scores of on-line courses compare with standardized exam scores of traditional courses? D) How does course completion of on-line courses compare with completion of traditional courses?

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

whats the drop down answers ?

explanation:

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).

answercells,tissues,organs,organ,system-organism;

hope this .good luck
