The cloning of organisms is an exciting area of study, and more resources should be be devoted to it so it is refers as scientific explanation.

The age, type, and composition of ancient rocks in western Africa are nearly identical to the age, type, and composition of rocks in eastern South America is scientific observation which is taken by the scientist through research.

How do body systems work together to maintain homeostasis

Novosadov [1.4K]

Answer: By Hormonal action and Nervous coordination

Explanation:

Hormones are substances produced by one tissue and conveyed by the bloodstream to another to effect physiological activity. Homeostasis is the maintenance of a stable internal environment in the body.

Body systems such as digestive, circulatory, excretory systems etc, all are coordinated to achieve a STABLE INTERNAL ENVIRONMENT by the aid of HORMONES AND/OR NERVOUS COORDINATION.

For Example: the vasodilation of blood vessels during hot weather, and the opposite action of vasoconstriction during cold weather are both controlled by Hormonal action and nervous coordination which leads to a stable body temperature preventing excess heat accumulation.

Also, Nervous system controls the body systems, such that the muscle contractions are joined to actions like sweating, breathing, respiration etc

So, to maintain homeostasis hormonal action and Nervous coordination is necessary.
