Question

complete the table to compare triglycerides, phospholipids, and steroids.

	triglycerides	phospholipids	steroids
have carbon atoms arranged in long chains
have carbon atoms arranged in rings

Explanation:

Step1: Analyze "are a type of lipid"

Triglycerides, phospholipids, and steroids are all types of lipids. So we mark a check ($\checkmark$) for each.

Step2: Analyze "have carbon atoms arranged in long chains"

Triglycerides (composed of fatty acids with long carbon chains) and phospholipids (have fatty acid tails with long carbon chains) have carbon atoms in long chains. Steroids have carbon atoms in ring structures, not long chains. So we mark $\checkmark$ for triglycerides and phospholipids, and leave steroids blank.

Step3: Analyze "have carbon atoms arranged in rings"

Steroids (e.g., cholesterol) have a characteristic structure with carbon atoms arranged in rings. Triglycerides and phospholipids have long carbon chains, not ring structures. So we mark $\checkmark$ for steroids and leave the others blank.

Answer:

	triglycerides	phospholipids	steroids
have carbon atoms arranged in long chains	$\boldsymbol{\checkmark}$	$\boldsymbol{\checkmark}$
have carbon atoms arranged in rings			$\boldsymbol{\checkmark}$
