Answer to Question 1

B

Answer to Question 2

Meiofauna are small marine organisms that live in the spaces between sediment particles. These organisms, generally only 0.1 to 2 millimeters long, feed primarily on bacteria removed from the surface of sediment particles. Meiofauna include polychaetes, mollusks, arthropods, and nematodes and live in sediment from the intertidal zone to deep-ocean trenches.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
