Question

Cardiac muscle is striated.

Why is this beneficial?
A. because striated muscle has digestive enzymes, allowing it to
break through clogged arteries
B. because striated muscle tires easily
C. because striated muscle is voluntary, allowing you to stop your
heartbeat if necessary
D. because striated muscles can be trained, allowing you to
strengthen your heart with exercise

Answer 1

D. because striated muscles can be trained, allowing you to strengthen your heart with exercise

Step-by-step explanation:

Striated muscles convert chemical energy into physical work. You can make your striated muscles stronger with exercise. This helps the heart perform its function better and more efficiently.

Striated muscle does not have digestive enzymes and does not play a role in digestion. Striated muscles are very strong, and besides, that doesn't show why its beneficial anyway. It is impossible to voluntarily stop your heartbeat. If you did, you'd die.

Therefore, the best answer is D.
