Lipids
Glucose
Proteins
Carbohydrates
The Correct Answer is C

B. Glucose: Glucose is a carbohydrate used for energy, not for building hormones or hemoglobin.

D. Carbohydrates: Carbohydrates provide energy but do not contribute to the structure of proteins like hormones and hemoglobin.

C. Connective tissue: Connective tissue includes bone, blood, cartilage, and adipose tissue, none of which are classified as squamous, cuboidal, or columnar.
