<span>In DNA and RNA, the phosphodiester bond is the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another, deoxyribose in DNA and ribose in RNA. Strong covalent bondsform between the phosphate group and two 5-carbon ring carbohydrates (pentoses) over two ester bonds.</span>
Answer:
Due to the dense atmosphere
The magnetic field of the earth
Explanation:
Most particles in the solar wind do not reach the earth's surface because the atmosphere is very dense and the protecting magnetic field of the earth.
A solar wind is a burst of energetic particles from the sun which are made up electrons, ions, etc.. They travel at a very high velocity.
- The magnetic field of the earth is able to deflect these charged particles away.
- In areas such as the pole, the interact with the atmosphere to produce very stunning auroras.
The correct answer is bacteria. Bacteria abundant in soil is the main source of its organic matter. This is because bacteria release energy in their systems which causes the soil to be more fertile and more capable of sustaining plant material. Without bacteria general processes of soil formation will not be possible.
2NH3 is equivalent to N2 + H6 since the 2 at the beginning gets distributed to both atoms. Knowing this you can rewite the equation as
H2 + N2 = H6 + N2
The N2 can cancel out leaving
H2 = H6
You now have to ask ‘2 times what equals 6?’ The answer is obviously 3 at this point.
Answer: C. 3
