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.
Answer:
<em>The above statement is false. </em>
Explanation:
Domestic use of water refers to a city using certain amounts of water. It is not only limited to the water use in the household but also refers to the water usage of different places like restaurants, cafes, companies, malls of a city. Hence, we cannot say that domestic use of water only refers to the water being used in private households. So, the above statement will be considered to be false.
Answer:
Explanation: In plants, carbon dioxide (CO2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.
Genetic variance increases the chance of survival because through an enlarged gene pool, the chances of successful mutations is higher, as well as the favoring of successful traits.
An example of this is in birds, some species with large gene pools in a single geographic location will favor males with longer tail feathers, therefore that trait will become more common and increase the chance of survival through improved genetics within offspring.
