Under the effects of Aldosterone:
A. The urine will have less water content
B. The urine will have less sodium content
C. The urine will have more water content

B. direct humoral stimulation of adrenal cortex cells by potassium ions
C. ACTH during conditions of severe stress
D. Atrial natriuretic pepside causing inhibition of aldosterone effects
