Biochemical similarities, fossils and embryos (Google form)

Name

1. Which species is the most recent ancestor to humans?

• Gorilla
• Rhesus Monkey
• Lamprey
• Mouse

2. The presence of the same type of blood protein, hemoglobin, in different species of organisms indicates that-

• the species have identical genomes
• the species are classified at the same species
• the species share a common ancestor
• the species would not be classified in the same taxa

3. Similarities among organisms on the structural and metabolic levels are reflected in the large degree of similarity in-

• fossils
• proteins and nucleic acids of different organisms
• human genomes
• ecosystem

4. Which species is the least likely to be a common ancestor of a human?

• lamprey
• chicken
• frog
• mouse

5. According to the DNA sequences shown in the figure, which two species are most closely related?

• Species B and D
• Species B and C
• Species C and D
• Species A and B

6. A scientist trying to classify an unknown species collects the above amino acid sequences. Based on the sequence data, which species is the unknown species most closely related to?

• A
• B
• C
• D

7. Comparison of the DNA sequences of human, gorilla, and chimpanzees show that-

• gorillas and chimpanzees have identical DNA
• humans are very closely related to gorillas
• humans, gorillas, and chimpanzees have identical DNA
• humans are very closely related to chimpanzees

8. Any remnant or trace of an organism of a past age, such as a skeleton or impression preserved in the Earth's crust, is called a-

• fossil
• shell
• bone
• carcass

9. Fossils allow scientists to -

• decode past human migratory patterns
• compare structural characteristics of an extinct organism
• decode pase CO2 emissions
• determine environmental factors that caused extension of certain plants and animals
