Answer to Question 1

B
Feedback:
Botulinum toxin types A and B bind directly to the receptor sites of motor nerve terminals and inhibit the release of acetylcholine, leading to local muscle paralysis. These two drugs are injected locally and used to paralyze or prevent the contractions of specific muscle groups. The action smoothes wrinkles in the area, but does not cause muscle death. The effect is temporary and does not cause nerve death. The other options are false statements.

Answer to Question 2

A
Feedback:
When the antigens and antibodies react, they form an antigenantibody complex. This new structure reveals a new receptor site on the antibody that activates a series of plasma proteins in the body called complement proteins. Options B, C, and D are distracters for this question and are not involved in this process.
