NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions.
About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations.

Q3. CO_2,CH_4,N_2 O and CFCs are called green house gases, because they can absorb
Solution
Green house gases are those gases, which are transparent to solar radiations but retain and partially reflect back long wave heat radiations, i.e., infra red radiations. The various green house gases are CO_2,CH_4,CFCs,N_2 O,O_3 and water vapours.Green house gases are those gases, which are transparent to solar radiations but retain and partially reflect back long wave heat radiations, i.e., infra red radiations.

Q4. Removal of forest areas to fulfill the needs of growing human population is called
Solution
Population growth possesses serious threat to the forest. The forest are the basis needs of everyday life as they provide us food, shelter and raw material for other essentialities but these forests are deforested for fulfilling the increasing demands of overpopulation like clearing of forests for agriculture, industries, urban area, etc.

Q6. According to the Central Pollution Control Board (CPCB), particles that are responsible for causing great harm to human health are of diameter
Solution
According to Central Pollution Control Board (CPCB), particulates size 2.5 micrometers or less in diameter (PM 2.5) are responsible for causing the greatest harm to human health. These fine particulates can be inhaled deep into the lungs and can cause breathing and respiratory symptoms, irritation inflammations and damage to the lungs and premature deaths.

Q9.SO_2 pollution is indicated by
Solution
Lichens (Usnea) are the indicator of air pollution, as these are very sensitive to air pollution (particularly SO_2pollution).

Q10. The ultraviolet radiations in the stratosphere are absorbed by
Solution
Ozone layer is confined to the stratosphere. It is formed when sunlight reacts with O_2molecules. The ozone protects the earth from harmful UV-rays by absorbing them.
