Correct answer: C) Concentration gradient
The process of movement of a particle in a solution from the region of higher concentration to the region of lower concentration across a membrane is called as concentration gradient.
For example: If we drop a few drop of dye in a glass of water, it will diffuse along a concentration gradient, i.e, the region where dye is found in highest concentration to the region where it is in lower concentration.
It will occur until the concentration of dye become uniform in all the direction in the glass of water.

It has the ability to cause sore throat, scarlet fever and infections in different parts of the body.
Rheumatic fever takes places if the strep throat and scarlet fever is not treated on time.
In Earthquake testing, the engineers are using the world largest shake tables to test new construction methods for buildings in the areas prone to the earthquake.
<u>Explanation:</u>
They believed that they have the devised a system to build the taller wood-frame buildings that can still safely withstand even very powerful tremors. To withstand the collapse, the buildings need to redistribute the forces that travel through them during a seismic event.
Shear wells, cross braces, diaphragm, and moment-resisting frame are the central reinforcing the building. Shear wells are the technology of the useful building. That helpful to transfer the earthquake forces.
I don’t think we would have the same countries. i feel like everything would be connected, like maybe a few really big countries instead of hundreds of different countries. i feel we would look different that how we already look because there would be more of different type of people around each other, resulting in mixed race reproducing.
