Answer: A). 2.7 million people per year
Explanation:
From 2000 to 2010 is 10 years. Change in population in 10 years = population at the beginning of 2010 minus the population at the beginning of 2000. This is:
309 million -282 million = 27 million.
Therefore average change in population person year = 27 million/10 = 2.7 million per year
The following statement that is NOT part of the Cell Theory is B
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.
