Question: What is the organism type in the images?
Answer Options: Fungi Bacteria Protist Algae Correct Answer: Fungi
Question: Which of these environments would likely harbor Cryptococcus gattii?
Answer Options: Soils near the coast Damp wood Higher elevations Dry attic spaces Correct Answer: Soils near the coast Damp wood
Question: Which of the following is the most likely reason that this fungus became specifically problematic in 2001?
Answer Options: Climate change has caused increased temperatures, and they began to peak in 2001. There was a specific increase in population and deforestation in that year. The fungus had made a deal with the Y2K bug to wait a year and then emerge. There was a large tsunami that brought the fungus across from Japan. Correct Answer: Climate change has caused increased temperatures, and they began to peak in 2001.
Question: What is the order of the Cryptococcus life cycle?
Answer Options: Step 1: Fungus grows in hyphal form on trees and in soils. Step 2: Fungus releases spores into the air. Step 3: Spores are breathed into the lungs. Step 4: Spores enter white blood cells and replicate. Correct Answer: 1 – Step 1: Fungus grows in hyphal form on trees and in soils. 2 – Step 2: Fungus releases spores into the air. 3 – Step 3: Spores are breathed into the lungs. 4 – Step 4: Spores enter white blood cells and replicate.
Question: What would be some good experimental ways to test the hypothesis?
Answer Options: Try to swab the areas and grow them on simple media. Survey the people who were ill to find out where they had been recently. Examine only the nodules found in cats and dogs. Collect lung samples from sick and non-sick creatures to compare under a microscope and on plates. Ask everyone in town if they have touched any porpoises recently. Take environmental samples across the island to look for various microorganisms. Correct Answer: Try to swab the areas and grow them on simple media. Collect lung samples from sick and non-sick creatures to compare under a microscope and on plates. Take environmental samples across the island to look for various microorganisms.

Answer Options: Prokaryote Green in color Rod-shaped Round Approximately 20µm in diameter Approximately 2µm in diameter Internal organelles Thick cell wall Correct Answer: Round Approximately 20µm in diameter Internal organelles Thick cell wall
Question: What are some of the similarities between the scenarios presented in the video?
Answer Options: The problem affected organs, in some cases lungs and brains. The outer skin of all creatures was affected. The cases happened within a short time frame. There were clear signs of cancer cells. There seems to be an airborne component. Correct Answer: The problem affected organs, in some cases lungs and brains. The cases happened within a short time frame. There seems to be an airborne component.
Question: What would be a good hypothesis for this situation?
Answer Options: There might be bacteria or fungus involved in these incidences. These incidences are only found on Vancouver Island. The humans caught the disease from their pets. A microorganism is causing the damage to the organs in sick/dead creatures. Correct Answer: A microorganism is causing the damage to the organs in sick/dead creatures.
Question: A monopolistically competitive firm is operating at a short-run level of output where price is $15, average total cost is $21, marginal cost is $15, and marginal revenue is $12. In the short run this firm should:
Answer Options: increase the level of output. not change the level of output. reduce product price. decrease the level of output. Correct Answer: decrease the level of output.

Question: How does Cryptococcus gattii get to the brain?
Answer Options: It actually cannot reach the brain. It enters through the eyes. It goes directly through the olfactory nerve. It buds and travels inside of macrophages. Correct Answer: It goes directly through the olfactory nerve.
