Answer:
Heterogeneous
Explanation:
Sand may appear homogeneous from a distance but it is heterogeneous.
Answer:
The correct answer is - facilitated diffusion.
Explanation:
Facilitated diffusion is a form of facilitated transport of molecules such as amino acid, glucose, and others through the plasma membrane involving the passive or indirect movement of molecules along their concentration gradient, which is led by the presence of another molecule normally a pore or channel made up of integral protein.
Facilitated diffusion depends on several factors such as the size of molecules, type of molecules, similarity of molecules to extracellular matrix or fluid that slow or fast the diffusion process.
Thus, the correct answer is - facilitated diffusion.
