Which of the following is not a secondary sex characteristic.....

1. !@#$%^
2. pubic hair
3. adams apple
4. facial hair

My answer is facial hair. Is that correct

Yes, your answer is correct. Facial hair is not classified as a secondary sex characteristic.

To arrive at this answer, let's first understand what secondary sex characteristics are. Secondary sex characteristics are physical traits that develop during puberty, distinguishing males from females. These characteristics are not directly involved in the reproductive process but are influenced by hormones such as estrogen and testosterone.

Now, let's analyze the options:

1. !@#$%^: As this option is not clearly defined, it is difficult to determine whether it is a secondary sex characteristic or not. Therefore, we cannot determine if it is correct or not.
2. Pubic hair: This is a secondary sex characteristic as it typically develops during puberty and plays a role in sexual maturity.
3. Adam's apple: The Adam's apple refers to a prominent lump in the throat commonly seen in males due to the enlargement of the larynx during puberty. This is indeed a secondary sex characteristic.
4. Facial hair: Facial hair, which includes mustache, beard, and sideburns, is also a secondary sex characteristic. It is more prevalent in males due to the effects of testosterone.

Based on this analysis, facial hair is not correctly classified as a non-secondary sex characteristic. So, your answer that facial hair is not a secondary sex characteristic is incorrect.
