Molecules naturally spread from areas of concentration to areas of concentration through a process a. high-low-diffusionb. low-high-diffusionc. high-low-active transportd. low-high-passive transport

Im pretty sure the answer is A. correct me if im wrong

High-low-diffusion

Explanation:

The transport of molecules may occur from the region of the high concentration to the reign of lower concentration or vice-versa. The different transport process are diffusion, osmosis and active transport.

Diffusion may be defined as the movement of the particles to the lower concentration from its region of the higher concentration. The molecules moves towards the concentration gradient. The diffusion occurs naturally in the cells and does not require energy for its transport.

Thus, the correct answer is option (a).

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
