I believe that the answer to this question is energy!! because cells need energy and the reason they respire is for energy
Support, protection, movement, mineral homeostasis, blood cell production and storage.
Answer:
In order to obtain some materials and remove waste, what process is used by prokaryotes? Diffusion. The changes in the concentration help the movement of the particles and waste across the plasma membrane. This process is known as diffusion, where molecules move from high to low concentration.
Explanation:
Answer:
Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
Explanation:
This statement is true. Only active transport can move molecules up a concentration gradient using energy. Passive transport on the other hand, uses no energy and occurs naturally. Therefore molecules can only move a concentration gradient.
