BIO 105 Study Guide - Final Guide: Epithet, Binomial Nomenclature, Ribosomal Dna

NOTE: This lab assignment has questions related to binomial nomenclature. Please note that the assessment system does not accept formatted text, so you will need to indicate any italicized words by adding “IT” in parentheses after each word that is to be written in italics, (IT). For example, the common fruit fly is genus Drosphila and species melanogaster. When written, it is Drosophila melanogaster. From this example, the correct way to represent the italicized words is by typing, Drosphila (IT) melanogaster (IT).

Record the classes for each of the following arthropods, as determined from the dichotomous key (16 points): Organism 1 (Spider) Organism 2 (Bee) Organism 3 (Beetle) Organism 4 (Blue crab) Organism 5 (Crayfish) Organism 6 (Tick) Organism 7 (Fiddler crab) Organism 8 (Centipede) Organism 9 (Shrimp) Organism 10 (Millipede) Organism 11 (Wasp) Organism 12 (Grasshopper) Organism 13 (Horseshoe Crab) Organism 14 (Mole Crab) Organism 15 (Scorpion) Organism 16 (Squilla) Provide the family name for each shark based on the use of the dichotomous key provided (14 points): Shark 1 Shark 2 Shark 3 Shark 4 Shark 5 Shark 6 Shark 7 Shark 8 Shark 9 Shark 10 Shark 11 Shark 12 Shark 13 Shark 14 Submit the dichotomous key for the "imaginary" animals. (10 points) When might a prepared key be used to identify biological organisms? (5 points) Why are there only two choices for each step in the dichotomous key? (3 points) Why are observation skills important when working with dichotomous keys? (5 points) List the domain, kingdom, phylum, subphylum, class, order, family, genus, and species of humans. (9 points) domain kingdom phylum subphylum class order family genus species What is the scientific name for humans? (4 points) It is estimated that there are more than 1 million species of insects on this planet. Based on this and information gained from this laboratory, what phylum most likely comprises over 90% of the Earth's species? Briefly justify your answer. (4 points) Scorpions and spiders both belong to the same class called Arachnida. Birds and fish both belong to the phylum Chordata. Which two organisms are more closely related? Explain why. (5 points) Using the evolutionary distances from the protein sequences activity (Step 4 of the procedures), fill in the diagram below. The letters should correspond with the sequence numbers (e.g., 1, 2, 3, 4, or 5). (5 points) A B C D E
