Jessica recently moved to an apartment in the industrial area of readington city. she noticed that the roads in her neighborhood warm up quickly. she also noticed that the temperature in her apartment is typically much warmer than the temperature of her previous apartment, which was near the mountains on the outskirts of the city. what is responsible for the change in temperature?

a. urban areas absorb more of the sun’s radiation.
b. mountainous areas don’t absorb the sun’s radiation.
c. mountain areas experience more precipitation.
d. urban areas experience lower precipitation.

The correct answer is option A, that is, urban areas absorb more of the Sun’s radiation.

Explanation:

The cause for the urban regions exhibiting a warmer climate in comparison to the mountainous regions is the maximum captivation of the radiation of the Sun by these regions. This is termed as the urban heat island effect. This results in the air to be warmer in comparison to the other regions.  

There are various causes related to the elevation in the temperature. One of the causes is exhibiting a huge number of roads and buildings in the urban regions. This takes part in the captivation of the heat from the Sun. Another cause is the absence of green plants, which absorbs the heat and the cools the surrounding.  

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
