BIOLOGY - Homeostasis and Health Maintaining Environmental Stability The internal environment of living things must remain relatively constant. Many systems work together to maintain stability. Stability is challenged by changing physical, chemical, and environmental conditions as well as the presence of disease agents. Describe how cells function in a narrow range of physical conditions, such as temperature and pH (acidity) to perform life functions. Describe how the maintenance of a relatively stable internal environment is required for the continuation of life. Explain how stability is challenged by changing physical, chemical, and environmental conditions as well as the presence of disease agents. Homeostasis The internal environment of living things must remain relatively constant. Many systems work together to maintain homeostasis. When homeostasis is lost, death occurs. Describe how human body systems maintain relatively constant internal conditions (temperature, acidity, and blood sugar). Explain how human organ systems help maintain human health. Describe the structures of viruses and bacteria. Recognize that while viruses lack cellular structure, they have the genetic material to invade living cells. Internal/External Cell Regulation Cellular processes are regulated both internally and externally by environments in which cells exist, including local environments that lead to cell differentiation during the development of multicellular organisms. During the development of complex multicellular organisms, cell differentiation is regulated through the expression of different genes. Explain that the regulatory and behavioral responses of an organism to external stimuli occur in order to maintain both short- and long-term equilibrium.
