Human lack chlorophyll, which is the function that collects energy from the Sun to conduct photosynthesis.
The mechanism for the given reaction by adding the missing bonds, charges, nonbonding electrons, and curved arrows is as represented in the attached image.
<h3>Mechanism of Organic Reactions</h3>
The representation of an organic reaction mechanism typically includes designation of the overall reaction type (which may be substitution, addition, elimination, oxidation, reduction, or rearrangement), the presence of any reactive intermediates, the nature of the reagent that initiates the reaction, the presence of any catalysis as facilitated by a catalyst, and ultimately it's stereochemistry.

Answer:
a) 20 m/s
b) No
Explanation:
a)
Mr. G needs to run x= 200 m in t = 10 seconds to catch the bus.
Knowing the speed is computed as

We have

b)
The fastest human can run 12 m/s, so Mr. G won't be able to catch the bus because he needs to run faster than that
