Viewing systems from multiple perspectives.
Discovering causes and effects using model tractability.
Improving system understanding through visual analysis.
Explanation:
Got this from google, lol. But, I put three here just in case you could get extra credit for more than two.
Answer:
By comparing the bonds between C-H and O-H, the O-H bond has the greatest degree of polarity.
Explanation:
Based on bond electronegative values which is a measure of the ability of a atom in a chemical bond to pull the shared electrons closer to its self.
The electronegativity of an element characterizes the elements chemical reaction.
From the available bonds
Oxygen has an electronegativity value of 3.44 and Carbon 2.55, while Hydrogen has an electronegativity value of 2.20
Therefore the bond between carbon and hydrogen is much less polar than between oxygen and hydrogen.
The bond between oxygen and hydrogen has the greatest polarity.
The answer is E.
Chemoautotrophs are organisms that use inorganic <span>compounds as an energy source and CO2 as a carbon source. The organisms live in </span>hostile environments like dark depths of the sea. Inorganic energy sources that they use are mostly hydrogen sulfide, elemental sulfur, ferrous iron, molecular hydrogen, and ammonia.
