Answer:
Movement of particles from a region of high concentration to a region of low concentration
Explanation:
- Diffusion can be defined as the movement of particles from a region of high concentration to a region of low concentration.
- Diffusion is a special type of diffusion that involves movement of solute molecules from a region of a high concentration to a region of high concentration until equilibrium is achieved.
- Diffusion is a passive transport of particles, which means it does not involve use of energy in the form of ATP like the case of active transport.
This is because cells are not only characterized by their genetic material and other interior components but also by genes they express cells have to fulfill multiple different functions to be able to build complex multicellular organisms

Answer;
+1,-1,+2,-2,+3,-3
Explanation;
-Valence is the number of electrons lost or gained to complete an element's outer energy level.
-When an atom gains or loses a valence electron, it forms an ion. Atoms form ions in order to help another to obtain a full octet and to stabilize the valence.
-Some atoms gain or lose electrons to form ions because they need to become more stable. They sometimes give them to have an outer shell or gain them to get a closer charge to eight.
They give extra surface area to be able to collect more oxygen molecules.
