Statement I is correct, as hormones can have opposite effects on the same process to maintain homeostasis (e.g. insulin and glucagon regulating blood glucose levels).
Statement II is incorrect, as hormones of the same chemical class can have different functions (e.g. catecholamines can act as both hormones and neurotransmitters).
Statement III is incorrect, as hormones are secreted by specialized cells usually located in endocrine glands, not exocrine.
Statement IV is correct, as hormones are often regulated by feedback loops that maintain balance in the system.
