Final answer:
Homeostasis is the term used to describe the ability of organisms, including humans, to maintain a stable internal environment. Weight thermostats are influenced by both environmental and biological factors and help regulate body weight.
Step-by-step explanation:
Homeostasis is the term used to describe the ability of organisms, including humans, to maintain a stable internal environment in the face of changing external conditions.
Weight thermostats are part of the homeostatic mechanisms that regulate body weight. They are influenced by both environmental factors, such as food availability and cultural norms, as well as biological factors like metabolic rate and genetics.
For example, if a person consistently consumes more calories than they burn, their weight thermostat may adjust to maintain a higher weight set point over time. Conversely, if they consistently consume fewer calories than they burn, their weight thermostat may adjust to maintain a lower weight set point.
