Question

1. what is homeostasis, and how is it maintained in the human body?

homeostasis is the regulation of body temperature only and is maintained by the skeletal system.
homeostasis is the process of cell division and is maintained by positive feedback mechanisms.
homeostasis is the maintenance of a constant internal environment and is mostly maintained through negative feedback systems.
homeostasis is the ability to respond to external stimuli and is maintained by voluntary muscle control.

Explanation:

Homeostasis is the maintenance of a stable internal environment in the body, such as stable body - temperature, pH, and blood - glucose levels. Negative feedback systems are the main mechanism for maintaining it. For example, when body temperature rises, the body sweats to cool down.

Answer:

Homeostasis is the maintenance of a constant internal environment and is mostly maintained through negative feedback systems.
