Since these microorganisms contaminate the earth, we need a protocol to disinfect the spaceship. The microbes that are found on space ships are the organisms that survived the trip from spaces and can survive in both space and earth environments. In a biofilm on a deep-sea hydrothermal vent, microorganisms survive at temperatures above 100C. If a sample were to be taken from the biofilm, many of the microbes would die on their way up to sea level, since it is not their ideal environment.

To disinfect a spaceship, we can use gaseous sterilants since they will denature the proteins in the microorganisms. Once the protein is denatured, the microbe can no longer function. A gas chamber large enough to fit the spaceship can be designed to house the spaceship and disinfect it until its next use.

This year’s flu, which is dominated by H3N2 (an influenza A strain), has caused severe morbidity and mortality. The virus is usually spread through contact with aerosols and droplets, and introduced into epithelial cells of the respiratory tract. Both you and your wife caught flu two-three week ago, and had miserable time with similar symptoms although you got sick first and then she came down 1 week later. In addition to experiencing local symptoms, like sore throat and nasal congestion, you two also had systemic symptoms, such as fever and muscle pain. Many of these symptoms likely reflect ongoing immune reactions. Ten days later, you recovered completely. With the knowledge just learned in the past three lectures, please describe how your immune system worked to fight off the infection.

To determine if you developed virus-specific T cell immunity, you collected CD8+ T cells from your own blood (not your wife’s) and expanded some epithelial cells isolated either from your own nasal swap or nasal isolate of your wife (assuming you could collect these cells). These epithelial cells were infected in a test tube to serve as targets (i.e., target/H3N2) for analyzing activity of your CD8 cells. Specifically, you mixed your CD8+ cells with either your own epithelial cells (target-A) or epithelial cells derived from your wife (target-B), illustrated as below, would these target cells be killed by your CD8 cells and why?

1.CD8+ cells + Target-A/H3N2

2.CD8+ cells + Target-B/H3N2

1) Why is codon bias important?

2) If you had a bacterial cell in a solution of sodium at 0.5 M outside the cell and 0.8 M inside the cell and K+ at 0.3 M outside the cell and 0.5 M inside the cell. If this is an antiporter, with the sodium coming into the cell as the as potassium (K+) moves out of the cell, which molecule sodium or potassium provides the energy for this transporter? How do you know?

Experiment 2

QUESTIONS:::PLEASE ANSWER ALL QUESTIONS AS THEY GO TOGETHER. Everytime questions that go together get split up and not answered i have to repost and other people dont know how to answer questions so my questions get wasted and incorrect answers from not knowing previous question or answer.

25. How would you know if your results from experiment 2 show that the traits were inherited through Mendelian genetics?

27. Determine the Χ2 value for Experiment 2 using the following equation. Record your answer for use in a later question. Show your work.

28. Use the degrees of freedom and Χ2 value from earlier questions to determine the p value for Experiment 2 using the table of critical values for Χ2. Record your answer for use in a later question.

29. Use the hypothesis, degrees of freedom, Χ2, and p value determined in earlier questions to conclude whether corn #2 is following Mendelian genetics. Explain your reasoning.
