Which term describes the stable internal conditions of an organism?
A
cell specialization
B
homeostasis
C
permeability
D
unicellularity
Explanation: 

Detailed explanation-1: -Homeostasis is the maintenance of a stable internal environment. Homeostasis is a term coined to describe the physical and chemical parameters that an organism must maintain to allow proper functioning of its component cells, tissues, organs, and organ systems.

Detailed explanation-2: -The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.

Detailed explanation-3: -Homeostasis, from the Greek words for “same” and “steady, ” refers to any process that living things use to actively maintain fairly stable conditions necessary for survival. The term was coined in 1930 by the physician Walter Cannon.

Detailed explanation-4: -Summary. Homeostasis is the ability of the body to maintain a stable internal environment despite a changing external environment. Homeostasis is maintained primarily through negative feedback, when a response to a stimulus keeps a variable close to a set value.

Detailed explanation-5: -The body maintains homeostasis for many factors. Some of these include body temperature, blood glucose, and various pH levels. Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature.
