You Are a Lab Technician Staining Sections of Skeletal Muscle

You are a lab technician staining sections of skeletal muscle using a stain that binds to mitochondria.The tissue comes from leg biopsies of two patients: a professional weight lifter and a competitive long distance runner.You realize the slides are unlabeled.How might you determine which slide belongs to which patient?

A) The slide showing more slow-twitch muscle and fewer mitochondria per cell would be from the long distance runner.
B) The slide showing more red muscle and more mitochondria per cell would be from the long distance runner.
C) The slide showing more fast-twitch muscle and fewer mitochondria per cell would be from the long distance runner.
D) The slide showing more white muscle and more mitochondria per cell would be from the weight lifter.
E) The slide showing more red muscle and more mitochondria per cell would be from the weight lifter.
