Correct answer: A). Earth’s average temperature will increase.
Green house gases are those gases, which are present in the air that have the ability to trap heat of the earth's surface. Gases like carbon dioxide and methane are known to be found naturally play an important role in earth's climate. If they are not found the earth' s climate would be too cold creating problem for survival of life on the earth.
They absorb and emit the radiation in the thermal infrared range. These gases act like a blanket and save earth surface from infrared radiation by absorbing them and prevent them from escaping out of the earth surface.
But due to increased in the concentration of green house gases like carbon dioxide and methane in the environment due to pollution and deforestation is causing a great problem, which result in a global warming, which is a great concern for all the people on the planet. It will increase the annual global temperature which will result in the melting of glaciers. So, the issue of global warming should be taken seriously and adequate measure should be taken to control it.
D: All the variables are controlled except one.

Answer 1:
The mutation shown is point mutation.
A point mutation can be described as a type of mutation in which only a single nucleotide of a sequence is either:
The addition of the single nucleotide will cause the entire open reading frame to be changed. The amino acid sequence will change entirely from the position where the insertion mutation occurs. This is because the code for making amino acids works on a three base pattern. The reading of the three bases will be altered completely by the addition of just a single nucleotide.
Answer 2:
No, the resulting protein will not be altered.
The genetic code occurs in a linear sequence with triplet format. The change in a single base will cause the wrong amino acids to be formed. However, if the different code is common for the same amino acid then there will be no effect on the amino acid being formed.
<em>For example, the code GUA makes the amino acid Valine. If a mutation occurs and the code becomes GUU instead of GUA, then the resulting amino acid formed will also be Valine. Hence, there will be no alternation in the formation of the protein.</em>
Answer 3:
Melanoma cancer is the type of skin cancer which is associated with cancer from sun light. It is mainly caused due to the harmful ultraviolet rays which act as a mutagen.
<em>The mutations might keep coming back because although the growth have been removed, the other skin cells of the body might still have the mutation in them. As a result, growth will be seen again in the skin cells which might occur again and again. </em>
