Naegleria fowleri, also known as the ‘brain-eating amoeba’, causes deathly amebic meningoencephalitis in humans.  However, this pathogen is typically free-living and humans cannot transmit them to any other potential host.  What type of virulence evolution hypothesis does this demonstrate?   a. Coincidental evolution hypothesis   b. Short-sighted evolution hypothesis   c. Cost/trade-off evolution hypothesis

Question 5 You are studying a species of tree frog with skin that produces different toxins based on the genotype of the Tox locuS. Alleles E and N are codominant. Individuals homozygous for E are emetic (eating them causes vomiting), while individuals homozygous for N produce a neurotoxin. Heterozygotic frogs produce a toxin with both qualities. At the La Selva Biological Station in Costa Rica, you collect frogs from the field site and test them in the lab. You find 93 neurotoxic frogs, 113 emetic frogs, and 12 frogs with both toxic qualities. Using the Hardy-Weinberg equilibrium equation, what are the expected numbers of frogs given their genotypes at the Tox locus? 45 NN, 108 NE, 65 EE B 93 NN, 12 NE, 113 EE 324 NN, 446 NE, 154 EE D) 198 N, 238 E Last saved 1. 67 minutes remaining P Type here to search Home DII PrtScn F8 F6 F7 F3 F4 F5

Question 4. You are analyzing cells that you have grown on coverslips and fixed. What method would you use to determine where in the cell a protein is located? A. Western blot B. SDS-PAGE C. Microarray D. Immnocytochemstry E. Single cell RNA sequencing
