Cells maintain internal stability
The correct answer is: Cells maintain internal stability.
Homeostasis is the process through which living organisms maintain a stable internal environment despite external changes. It is crucial for the proper functioning of cells and bodily systems. To achieve homeostasis, cells continuously monitor and adjust their internal conditions. Here is an explanation for each of the answer options:
1. Cells control voluntary movements: While the ability to control voluntary movements is important for an organism's survival, it is not directly related to achieving homeostasis. Voluntary movements are coordinated by the central nervous system.
2. Cells secrete stomach enzymes: The secretion of stomach enzymes is essential for digestion, but it is a specific function of certain cells and not the overall process of achieving homeostasis. Digestion is one aspect of maintaining a stable internal environment.
3. Cells maintain internal stability: This is the correct answer. Cells actively work to maintain a stable internal environment by regulating various factors such as temperature, pH, electrolyte balance, and glucose levels. They achieve this through processes like feedback mechanisms, cellular respiration, hormone regulation, and ion exchange across cell membranes.
4. Cells control involuntary movements: Involuntary movements, such as the contraction of heart muscles or smooth muscles in the digestive system, are controlled by the autonomic nervous system. While these movements are important for the overall function of the body, they are not directly related to achieving homeostasis.
In summary, homeostasis is achieved primarily through the efforts of individual cells in maintaining a stable internal environment by actively monitoring and regulating various factors.
