Sulfur dioxide is considered a serious air pollutant. SO2 emissions that lead to high concentrations of SO2 in the air generally also
lead to the formation of other sulfur oxides (SOx). SO, can react with other compounds in the atmosphere to form small particles, and
these particles contribute to particulate matter (PM) pollution. Small particles may penetrate deeply into the lungs and in sufficient
quantity can contribute to health problems. Which of these is NOT a source of SO2 pollution?
A)
manufacture of cement
B)
extracting metal from ore
burning fossil fuels by power plants
D)
trains, ships and heavy equipment that burn high sulfur content fuel

Describe the data used by Watson and Crick to determine the structure of DNA
they used Franklin's x-ray picture and data as well as other mathematical data to determine the specific structure of the DNA double helix. Compare and Contrast the structure of prokaryotic and eukaryotic chromosomes.
Data of X Ray diffraction is used by Watson and Crick to determine the structure of DNA.
What is X Ray diffraction?"X-ray diffraction is a phenomenon in which the atoms of a crystal, by virtue of their uniform spacing, cause an interference pattern of the waves present in an incident beam of X rays."This is used for determining the 3D structures of crystal.By using data of this method Watson and Crick gives helical structure of DNA.
Hence, the data used is of X Ray diffraction.

How does nuclear fusion make life on Earth possible?
A. creates the sun’s magnetic field
B. blocks radiation from reaching Earth
C. releases energy that warms Earth
D. creates Earth’s magnetic field
Answer:
C
Explanation:
Nuclear fusion is the process by which the Sun produces its energy. It converts mass into energy, which is radiated over most of our solar system. The pressure from the fusion reactions keeps the star from collapsing.
Without the Sun's energy, in the amount we receive, the Earth would likely be entirely frozen and beyond deathly cold. Take Pluto as an example :)
Nuclear fusion make life on Earth possible by releasing energy that warms Earth.
SIGNIFICANCE OF THE SUN:
The sun is the ultimate source of energy needed directly or indirectly by every living organism on Earth. Sun provides the energy which autotrophs use to synthesize food.HOW DOES THE SUN GET ITS ENERGY?
The sun, which is a giver, however, also requires energy to do the needful. The sun gets its energy from a process called NUCLEAR FUSION, which is the coming together of the nuclei of two atoms.Nuclear fusion generates a large amount of energy for the sun when it occurs. This energy is used by the SUN, whose life on Earth is dependent on.Therefore, nuclear fusion make life on Earth possible by releasing energy that warms Earth.

What is evolution? How can evolution be scientific when no one was there to see it happen?
Answer:
Evolution is looking back and using scientific inference to make a timeline on adaptation of a species over time.
Explanation:
Looking at skulls, skeletal remains and carbon footprints left behind, we can compare and date remains of early humans and other species from years ago and compare them to late and modern remains. Thus making a timeline and showing the slow evolution of our adapting species.
Fossils can usually be found in layers of
chronological order
radioactive dating
common ancestry
sedimentary rock
fossil record
metamorphic rock
nitrogen dating
timeline
Answer:
Sedimentary rock
Explanation:
All fossils are sedimentary rock. When an organism dies, layers of sediments pile on top of the organism, the sediments harden to become sedimentary rock. And for this reason, fossils cannot be igneous or metamorphic rock.
