Active transport requires energy passive transport does not
Answer:
The diencephalon consist of the thalamus and hypothalamus
The main function of the circulatory system is to move materials throughout the body, blood for cellular respiration, sugars for energy, leukocytes for immune support, and other nutrients necessary for proper homeostasis.
Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.
