Let’s invent an imaginary taxonomic group of insect. This group (Order) is very diverse (i.e., has many described species).  Of the following traits, I want you to choose 4 that are most often associated with insect Orders with high diversity.

Fill in the blank: And what about lions, are there really insect lions?  Yes there are, sort of, the Order (spelling counts!) contains species commonly called Antlions?

This question is worth 1 point. The enthalpy of formation of hydrogen peroxide H2(g) + O2(g) –> H2O2(g) is -136.3 kJ/mol. This reaction is [peroxide].

(16 pts.) This ether can be made via one of two combinations of starting materials. Identify the nucleophile and electrophile needed to accomplish this reaction for each path. Each side should feature an alkyl halide and a sodium alkoxide anion (negatively charged O).                          

What would be the output of the following code? If there is an error, write “ERROR” def magic(values):   if values == []:         return 0    elif values[0] % 2 == 0:         return 1 + magic(values[1:])     else:        return magic(values[1:]) print(magic([4, 7, 2, 9, 12]))

Database Application Considerations  A company has been storing financial data in a combination of Excel spreadsheets and a relational database system. While the spreadsheets are easy to use, they often result in duplicate data, inconsistencies, and security risks. The relational database system is more structured but requires a well-organized schema. Describe how a relational database could resolve some of the issues experienced with spreadsheets.
