Final answer:
Kepler's laws apply to planetary motion even if the system is not isolated. The heart is made of cardiac muscle, not smooth muscle. Sprinting is an anaerobic exercise.
Step-by-step explanation:
True or false: A planet-satellite system must be isolated from other massive objects to follow Kepler's laws of planetary motion. The statement is false. Kepler's laws describe the motion of planets in the solar system, which is not isolated, yet the laws still apply to a good approximation. Nonetheless, other massive objects can indeed perturb the orbits, but such influences are typically small.
True or False: The heart consists of smooth muscle tissue. This statement is false. The heart is primarily composed of cardiac muscle tissue, which is distinct from smooth muscle and is specialized for the continuous and rhythmic beating of the heart.
True or False: Sprinting is considered an anaerobic exercise. This statement is true. Sprinting is an anaerobic exercise because it requires short bursts of high-intensity effort that do not rely primarily on the presence of oxygen for energy production.
