Most Endocrine Glands Communicate with Their Target Tissues Using _____

Question

Most endocrine glands communicate with their target tissues using _____ signals.
A) frequency-modulated
B) amplitude-modulated
C) pitch-modulated
D) resonance-modulated

Accepted Answer

Endocrine glands communicate with their target tissues using amplitude-modulated signals, which means they vary the strength of their signals to convey different messages. Hormone levels can increase or decrease depending on the body's needs, and this is achieved through modulation of hormone secretion. Frequency modulation, pitch modulation, and resonance modulation are not commonly used in endocrine signaling.
