Question

the model shows the chemical structure of a steroid. steroids have carbon atoms arranged in six - atom or five - atom rings. but like in this model, people dont always label the carbon atoms.
select the true statements.
steroids have carbon atoms arranged in rings.
steroids contain nitrogen atoms.
steroids help regulate growth in the body.

Explanation:

1. For "Steroids have carbon atoms arranged in rings": The model and description state steroids have carbon in six - or five - atom rings, so this is true.
2. For "Steroids contain nitrogen atoms": The given chemical structure (showing C, H, O) and general steroid structure (typically C, H, O; some with N but not all, and this structure has no N shown) – so this is false (the check here is incorrect).
3. For "Steroids help regulate growth in the body": Steroids like hormones (e.g., cortisol, sex hormones) regulate growth, metabolism, etc., so this is true.

Answer:

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