Answer to Question 1

D
Sinus arrhythmia has the following identifying traits: rate decreases during expiration, rate varies by more than 10 from beat to beat, and rate increases during inspiration.

Answer to Question 2

A thymectomy has been shown to reduce the symptoms in about 70 of the patients with myasthenia gravis. This happens because the thymus is the source of the AChR antibodies that lead to the muscle weakness.
