for the question i think you meant to put

Explain why regular exercise is the best way to prevent flexibility issues. Why do activities like yoga, ballet, and gymnastics require better than normal flexibility?

but my answer to that is:

Regular exercise helps keep muscles healthy and in good shape. Muscle stiffness that reduces flexibility often results from the overuse of muscle, but inactivity also weakens muscles and can make them more susceptible to injury.

and to the next question its:

Activities like yoga, ballet, and gymnastics require better than normal flexibility because these activities require your body to move in different, more extreme ways.

Explanation: this should be correct

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
