Which term describes the relatively constant internal physical 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: -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-3: -Homeostasis: maintain relatively constant internal physical and chemical conditions. To achieve this cells will grow, respond to its environment, transform energy and reproduce.

Detailed explanation-4: -Characteristics of Homeostatic Systems Homeostasis is highly developed in warm-blooded animals living on land, which must maintain body temperature, fluid balance, blood pH, and oxygen tension within rather narrow limits, while at the same time obtaining nutrition to provide the energy to maintain homeostasis.

Detailed explanation-5: -Homeostasis maintains optimal conditions for enzyme action throughout the body, as well as all cell functions. It is the maintenance of a constant internal environment despite changes in internal and external conditions. In the human body, this includes the control of: blood glucose concentration. body temperature.
