Answer:

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest

If a DNA molecule is found to be composed of 35% thymine, what percentage of cytosine would be expected, and why?
-Dominant- [34]
We use Chargaff's rule to get the answer. [A] + [G] = [C]+ [T].    [A] + [G] + [C] + [T] = 100% Where is A is Adenine, G is Gaunine, T is Thymine and C is Cytosine. In DNA, Adenine always pairs with Thymine, and Guanine always pairs with Cytosine. Therefore if Thymine is 35%, then Adenine will also be 35% to make 70% in total. The remaining percentage will be 100% - 70% = 30%. The 30% will be shared equally among Cytosine and Guanine, at 15% each. Therefore Cytosine will be 15%

Carbon dioxide is released when which of the following phenomena occur?
LenaWriter [7]

Answer:

Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels ( wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide and water vapor.

These natural hydrocarbon fuels come from once-living organisms and are made from carbon and hydrogen, which release carbon dioxide and water when they burn.

Explanation:

So the answer is Fossil Fuels.

Name some of the traits mendel studied with his pea plants.
Scorpion4ik [409]
Gregor Mendel was an important scientist, considered to be the founder of the science of genetics. His experiments on the crossbreeding of plants and the passing down of favourable traits, led him to establish the laws of Mendelian inheritance. He was using pea plants for his experiments and he was studying seven different pea traits: pea shape and color, pod shape and color, flower color, plant size and position of flowers.
