Organsisms molntoln a balance between their calls and the enternal environment the a PH growth homeostosis cellulor respiration

## Step 1<br />The question is asking for the term that describes the process by which organisms maintain a balance between their cells and the external environment. The options provided are PH, growth, homeostasis, and cellular respiration.<br /><br />## Step 2<br />PH refers to the acidity or basicity of a solution, which is not directly related to the balance between an organism's cells and the external environment.<br /><br />## Step 3<br />Growth refers to the increase in size or number of cells, which is a process that can be influenced by the balance between an organism's cells and the external environment, but it is not the process itself.<br /><br />## Step 4<br />Cellular respiration is a process that cells use to produce energy, which is also not directly related to the balance between an organism's cells and the external environment.<br /><br />## Step 5<br />Homeostasis, on the other hand, is the process by which organisms maintain a stable internal environment despite changes in external conditions. This includes regulating factors such as body temperature, pH, and the concentration of ions in the blood. Therefore, homeostasis is the correct answer.
