Smooth.
D
It is impossible to tell from the image.
Verified step by step guidance1
Observe the image carefully and note the presence of striations, which are alternating light and dark bands.
Identify the nuclei in the image. In skeletal muscle tissue, nuclei are typically located at the periphery of the muscle fibers.
Consider the overall structure of the muscle fibers. Skeletal muscle fibers are long, cylindrical, and multinucleated.
Compare these characteristics with those of cardiac and smooth muscle tissues. Cardiac muscle also has striations but has centrally located nuclei and intercalated discs. Smooth muscle lacks striations and has spindle-shaped cells.
Based on the presence of striations and peripheral nuclei, conclude that the muscle tissue shown is skeletal muscle.
