To answer the question correctly, we need to understand what homeostasis means. Homeostasis is the process by which an organism maintains a stable internal environment despite external changes. It involves the regulation of various factors such as body temperature, blood sugar levels, pH balance, and hormone levels.
Out of the options provided, the correct answer would be "Cells maintain internal."
Cells play a crucial role in maintaining homeostasis as they constantly monitor and react to changes in the internal environment. They achieve this through various mechanisms including feedback loops and physiological processes:
1. Feedback loops: Cells use feedback mechanisms to respond to changes and maintain stability. For instance, negative feedback loops work to reverse any deviation from the desired set point. For example, if the body temperature rises above the set point, cells in the body trigger sweating to cool down the body and return it to the normal temperature.
2. Physiological processes: Cells carry out various physiological processes to maintain homeostasis. Examples include maintaining the balance of electrolytes and water in the body, regulating blood sugar levels through insulin secretion by pancreatic cells, and regulating blood pressure through the narrowing or widening of blood vessels.
By performing these functions, cells contribute to the overall maintenance of homeostasis in the body, ensuring that bodily functions can operate effectively within a narrow range of conditions.
