Questions 1. what are some similarities among the organisms listed on the cards? what are some differences? 2. what is the taxonomy of each organism from largest to smallest grouping? 3. what phyla do you have in your chart? 4. what classes do you have in your chart? 5. what orders do you have in your chart? 6. what families do you have in your chart? 7. give four examples of how either some or all of the organisms in this activity are related to one another based on how they are classified. 8. why is it important to classify living things?

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
