Using the information from problem 3, scientists do a further testcross using a heterozygote for height and nose morphology. the offspring are tall–upturned snout, 40; dwarf–upturned snout, 9; dwarf–downturned snout, 42; tall–downturned snout, 9. calculate the recombination frequency from these data; then use your answer from problem 3 to determine the correct order of the three linked genes.

answer: a) a compound microscope has a greater magnification ability than a simple microscope.

explanation:

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
