How does the pituitary gland's secretion of hormones differ from that of the adrenal gland?

A. Non-steroid hormones include lipid-based molecules.:Many non-steroid hormones are peptide- or amino-acid–derived and are water-soluble rather than lipid-based, although some non-steroid hormones (like thyroid hormones) are lipid-soluble exceptions.
B. Non-steroid hormones contain fatty acids.:Non-steroid hormones are typically peptides or amino-acid derivatives and do not characteristically contain fatty-acid structures.
C. Steroid hormones are derived from cholesterol.:Steroid hormones are synthesized from cholesterol, giving them a four-ring lipid structure that makes them lipid-soluble and able to cross cell membranes.
D. Steroid hormones are composed of amino acids.:Steroid hormones are not composed of amino acids; amino-acid composition is a feature of peptide hormones and some amine hormones.

A. Monocytes:Monocytes differentiate into macrophages and dendritic cells that perform phagocytosis and antigen presentation but do not produce antibodies.
B. Neutrophils:Neutrophils are short-lived phagocytic cells that ingest and destroy pathogens; they do not produce antibodies.
C. B lymphocytes:B lymphocytes (B cells) differentiate into plasma cells that secrete antibodies specific to antigens, making them the primary source of antibody production.
D. T lymphocytes:T lymphocytes are involved in cell-mediated immunity, regulating immune responses and directly killing infected cells but not in producing antibodies.
