9. Mushrooms belong to the kingdom:
a. Protista. c. Plantae.
b. Bacteria. d. ***Fungi.***

10. This diagram shows the evolutionary relatedness of eight species based on similarities in DNA sequences. The vertical black bars represent where there are differences in the DNA bases between groups or pairs of species. Which statement is supported by the data represented in the diagram?
a. ********Species pair G and H have three different in their DNA, and most closely related to species pair, C and D********
b. Species pair G and H have three different in their DNA, and more closely related than the other species pairs
c. Species pair C and D have one difference in their DNA, and they share a common recent ancestor with species pair, G and H
d. Species pair A and B have one difference in their DNA, and more closely related than the other species pairs

11. The kingdom Plantae contains primarily:
a. ***photosynthetic autotrophs. *** c. photosynthetic heterotrophs.
b. single-celled autotrophs. d. protists.

12. The organisms found in the kingdom Animalia are:
a. multicellular autotrophs. c. ***multicellular heterotrophs.***
c. single-celled autotrophs. d. protists.

13. In to how many domains are organisms divided?
a. ***Three*** c. Four
b. five d. Six

14. The group of organisms that can be just below the kingdom is called a:
a. domain. c. ***phylum.***
b. species. d. class.



15. According to the cladogram, monotremes and eutherians had a common ancestor 146 million years ago.
a. ***True*** b. False

16. The ostrich, emu, rhea, and kiwi are four bird species that live in four different parts of the world. They all have feathers, small wing and breastbone (keel) structures that indicate an inability to fly, and similar mouth structures. However, each species has a different body size and color. Based on this information, which of the following is most likely to be true?
a. These four bird species probably evolved from different ancestors. They share similarities because there are certain features that are important for all birds to have
b. These four bird species probably have a common ancestor, but evolved independently so they developed differences
c. These four bird species probably have a common ancestor, any differences are due to mutations in individual current-day birds
d. *******These four bird species probably evolved from different ancestors due to their locations, and any similarities are a coincidence*******

17. Which of the following are NOT factors that contribute to natural selection?
a. Overproduction of offspring
b. Inheritance of unfavorable variations
c. ***Inheritance of favorable variations***
d. Survival and reproduction of individuals with favorable variations
