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).

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
