Answers:
1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.
2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.
3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.
Step-by-step explanation:
Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.
Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.
Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.
The yellow powder and the blue liquid producing a clear green liquid after mixing shows that these two substances are soluble.
The soluble substances are those which are completely mixed in each other producing a new solution. The insoluble substances are those, which do not mix together with each other, and remain separated. The miscible substances are those liquids which completely mix with each other forming a homogeneous mixture, while the immiscible substances are those liquids that do not form a homogeneous mixture when mixed.
Hence, the answer is 'soluble'.
Please double check my answer but I believe its the Golgi Apparatus. ??
