Which of the following regarding the assumption of sphericity is false? (Hint: Even very small departures from sphericity produce large biases in the F-test.)
Sphericity does not affect post hoc tests.
The effect of violating sphericity is a loss of power (i.e., an increased probability of a Type II error).
When sphericity is violated, we need to adjust the degrees of freedom for any F-ratios affected by the violation.
When sphericity is violated, the Bonferroni post hoc test can be used.
Answer:
The answer is C: motor end plate.
Explanation:
The region where somatic neurons join a skeletal muscle is known as a motor terminal plate. These plates are formed by an axon and a muscle fiber. Depolarization is produced by a nerve stimulation activating the corresponding muscle; Each muscle has its own motor plate and its corresponding axon.

Answer:
Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
