Question

we would expect cells found in the active muscles of animals to contain relatively large amounts of which cellular organelle? a centrioles b mitochondria c lysosome d nuclei

Explanation:

Mitochondria are the power - houses of the cell, producing ATP through cellular respiration. Active muscles require a large amount of energy, so they need many mitochondria to meet this energy demand. Centrioles are involved in cell division, lysosomes in digestion of waste, and nuclei in storing genetic information, none of which are as directly related to energy production for muscle activity as mitochondria.

Answer:

B. mitochondria
