Question

select the true statements. steroids help regulate growth in the body. steroids contain nitrogen atoms. steroids have carbon atoms arranged in rings.

Explanation:

1. Regulation of Growth: Steroids (e.g., growth hormone - related steroids, steroid hormones like testosterone/estrogen) play roles in growth regulation.
2. Ring Structure: The given steroid structure (and all steroids) has carbon atoms in fused ring systems (typically 3 six - membered and 1 five - membered ring in cholesterol - type steroids).
3. Nitrogen in Steroids: Most common steroids (like cholesterol, cortisol) have C, H, O. Nitrogen is not a typical component of the basic steroid structure (the structure shown has C, H, O only), so the "contains nitrogen" statement is false.

Answer:

The true statements are:

• Steroids help regulate growth in the body.
• Steroids have carbon atoms arranged in rings.

(Note: The statement "Steroids contain nitrogen atoms" is incorrect. Most steroids (e.g., cholesterol - based steroids) have C, H, O; only some (like steroid hormones with amine groups or steroid alkaloids) might have N, but the general steroid structure (like the one shown, which resembles cholesterol - derived steroids) does not contain N. So the initially checked "Steroids contain nitrogen atoms" is a mistake.)
