Correct Answer: A. 432

Explanation

\((3x + 4)^{4} = ^{4}C_{0}(3x)^{0}(4)^{4} + ^{4}C_{1}(3x)^{1}(4)^{3} + ^{4}C_{2}(3x)^{2}(4)^{2} + ^{4}C_{3}(3x)^{3}(4)^{1} + ^{4}C_{4}(3x)^{4}(4)^{0}\)

\(x^{3} = ^{4}C_{3}(3x)^{3}(4) = \frac{4!}{3!1!} \times 3^{3} \times 4\)

= \(432x^{3}\)

Correct Answer: C) muscles or glands which work in response to the stimulus received from the motor nerves.

Explanation

The question is asking about effectors in the body. Effectors are muscles or glands that work in response to the stimulus received from the motor nerves. In other words, effectors are parts of the body that respond to signals from the nervous system by either contracting (in the case of muscles) or secreting (in the case of glands). Option A states that effectors are only muscles. While muscles are a type of effector, this option is not completely correct as it does not include glands which are also effectors. Option B states that effectors are only glands. Again, this option is not completely correct as it does not include muscles which are also effectors. Option C is the correct answer as it includes both muscles and glands as types of effectors. Option D is incorrect as efferent neurons are not effectors. It is important to note that effectors are an important part of the nervous system and are responsible for carrying out the actions that are initiated by the nervous system. Examples of effectors include skeletal muscles, smooth muscles, and glands. To learn more about the nervous system and its components, please read the relevant sections of the recommended textbooks.
