I have no idea how to solve them. Plz provide theanswers with explanation
The crocodile, which can remain under water without breathing for up to 1 h, drowns its air-breathing prey and then dines at its leisure. An adaptation that aids the crocodile in doing so it that it can utilize virtually 100% of the O2in its blood whereas humans, for example, can extract only ~65% of the O2in their blood. Crocodile Hb does not bind BPG. However, crocodile deoxyHb preferentially binds HCO3ꟷ. How does this help crocodile obtain its dinner? Explain your answer.

Keeping with the theme of autumn, one of Dr. Danahy’s favorite molecules is caffeic acid due to its presence in pumpkins. This structure serves as an antioxidant and is one of many found within pumpkins. Despite its name, it bears no resemblance to caffeine. Answer the following questions about caffeic acid. The carbonyl stretch for caffeic acid is unusually low for a carboxylic acid at 1646 cm-1. For reference, the carbonyl stretch for propanoic acid is 1716 cm-1. Explain why the carbonyl stretch occurs at a lower wavenumber for caffeic acid.
