The macromolecule that helps with transport is Proteins.
The correct answer is: Maintaining constant internal conditions. Homeostasis involves the regulation of variables such as temperature, pH, and nutrient levels to ensure optimal conditions for cellular function.
The macromolecule that helps with transport is Proteins. Proteins play a crucial role in various forms of transport, including the transport of molecules across cell membranes and the transportation of oxygen in the blood.
Homeostasis is the process of maintaining constant internal conditions within an organism despite external changes. Therefore, the correct answer is: Maintaining constant internal conditions. Homeostasis involves the regulation of variables such as temperature, pH, and nutrient levels to ensure optimal conditions for cellular function.
