This document contains 14 multiple choice questions about biology. The questions cover topics like structures in plants that produce gametes, examples of how bacteria can be beneficial, fossil evidence that is considered intermediate between reptiles and birds, examples of fungi, implications of nucleic acids being complicated molecules, structures that seeds contain, fungal structures that result from sexual reproduction, examples of organisms that could have a pellicle structure, the scientist that showed amino acids can polymerize abiotically, plants that flourished along with dinosaurs, examples of archaea, examples of algae with spiral chloroplast arrangements, and implications of finding a Mesozoic era fossil in your backyard.

Question 13

8. The geological time scale indicates the order of Eras to be Cenozoic as the most recent,
the middle Era is the Mesozoic, with dinosaurs as the major group, and the earliest Era
being the Paleozoic. Consider a hillside of rock that surfaces in your backyard that is
identified as dating back to the Mesozoic Era. What is possible?
Select one:
a. Fossils from all other strata can still be found underneath if you dig far enough.
b. All periods of fossils had to be laid down in the backyard but higher ones were eroded
away.
c. Fossils were mainly deposited when your backyard was sediment, so many layers
might be missing, but any layer from Cenozoic to Paleozoic might be found.
d. Fossils were mainly deposited when your backyard was sediment, so many layers
might be missing, but any layer from earlier Mesozoic through Paleozoic might be found.
e. Only one layer of fossils can be found at any site.
