Answer B: Urban Heat Island (UHI) is an urban area that is significantly warmer than its surrounding rural areas due to human activities. UHI decreases air quality.
Answer C: The increased use of surrounding land is the main cause of biodiversity loss.
Answer D: Any field of environmental management help people to solve pollution problems. So, D is the correct answer.

Answer:
19.264×atoms are present in 3.2 moles of carbon.
Explanation:
It is known that one mole of each element is composed of Avagadro's number of atoms. This is same for all the elements in the periodic table.
So, as 1 mole of any element = Avagadro's number of atoms = 6.02× atoms
It is as simple as understanding a dozen of anything is equal to 12 pieces of that object.
As here the moles of carbon is given as 3.20 moles, the number of atoms in this mole can be determined as below.
1 mole of carbon = 6.02 × atoms
Then, 3.20 moles of carbon = 3.20 × 6.02 × atoms
Thus, 19.264×atoms are present in 3.2 moles of carbon.
A classic example of natural selection is the origin of giraffes long necks. The ancestors of modern giraffes were similar to deer with necks of ordinary length. Here natural selection accomplish Darwin's idea of "survival of the fittest". The correct option is A.
The mechanism through which living creature populations adapt and change is defined as the natural selection. The genes which are responsible for the survival of an organism are passed on to the successive generations.
Natural selection states that the organisms which are able to survive and reproduce with the changing environmental conditions are selected by the nature whereas the ones which cannot survive are eliminated.
So the survival of fittest means that the organisms which are suited to the environment will survive. Survival of the fittest is an expression developed from Darwin's theory of evolution.
Thus the correct option is A.
