a. What was the purpose of the Griffith’s experiment? (What question was asked?) b. Briefly explain the roles of Streptococcus pneumoniae and mice (mouse) in the experimental design. To answer this question, be sure that you address the independent variables.and dependent variables. If you wish, you can sketch a labeled figure to support your answer. c. Write a complete null hypothesis for his experiment.

A) Identify the INDEPENDENT variable in the experimental setup shown in the diagram. B) Describe at least two possible DEPENDENT variables that could be used to evaluate the results. C) List at least 3 variables that should be controlled in this experiment.

a)  Which concentration of anesthetic has the least variation in it's effect on muscle contraction?   Question 15 options:   10-6   10-7   10-10   10-8 b) What might the vertical capped bars (Τ) in the graph represent?  Choose all that apply.   Question 16 options:   standard deviation   standard error of the mean   degrees of freedom   number of replications of the experiment c) Which of the following statements accurately describes the effect of anesthetic on muscle contraction?  Choose all that apply.   Question 17 options:   There is a positive relationship between number of muscle contractions and mean anesthetic concentration decreases   There is a negative effect of anesthetic concentration on muscle contraction   As concentration of anesthetic is…

In one experiment, Griffith injected heat killed S strain bacteria into the mice. A. Whar was he trying to determine bybconducting this experiment? B. What were the results of this experiment? C. What conclusion did he reach based on these results?

Using your knowledge of Bayes’ Theorem, solve the following. A patient goes to see a doctor. The doctor performs a test where 95% of people who are sick test positive and 99% of the healthy people test negative. The doctor knows that only 1 percent of the people in the country are sick. (a)   What is the false positive rate?  (b)  The false negative rate? (c)  If the patient tests positive, what are the chances the patient is sick?

Most of the genetic information we will get from our genome will not be hard evidence that we will or we won’t get a disease but is rather only probabilistic evidence.   a. What does this mean? b. Why might knowing a single gene not tell you if you will get a particular condition?

I have seen that this was answered as C, Why is the answer C, how is that not evidence of it being genetic? Shouldnt it be none of the above? Question: Of the following, which supports the idea that alcoholism has no genetic or a low genetic component? a) Some strains of mice select alcohol over water 75% of the time, whereas others shun alcohol. b) The concordance value is 55% for MZ twins and 28% for DZ twins. c) Biological sons of alcoholic men who have been adopted have a rate of alcoholism more like that of their adoptive fathers. d) There is a 20% to 25% risk of alcoholism in the sons of alcoholic men. e) None of these.

In a study on the ecological impact of malarial infection in the lizard Scelopons occidentalis, researchers caught 15 lizards with the malarial parasite Plasmodium and 15 without. Researchers measured the distance (meters) each lizard could run in two minutes (as a measure of stamina). The following is the code and R output from the "t.test" function. t.test (x=infected, y=uninfected) Welch Two Sample t-test data: infected and uninfected t = -1.9658, df = 27.239, p-value = 0.05959 alternative hypothesis: true difference in means is not equal to 0 95 percent confidence interval: -10.9523489 0.2323489 sample estimates: mean of x mean of y 26.87333 32.23333 The confidence interval includes the value of 0, therefore we conclude that: a. The difference between the treatment and the placebo is positive b. There is no difference between the treatment and the placebo OC. The difference between the treatment and the placebo is negative Od. There is a difference between the treatment and the…

Watch the following video called "Human Genome Project Video" (https://fod.infobase.com/OnDemandEmbed.aspx?lti=1&token=30037&wID=97629&loid=0&w=400&h=300) then answer the following question in one paragraph each with evidence from the film to support your answers.  5) Answer in one paragraph and using the video provided to answer the following: There are companies now allowing people to clone their deceased pets. How do you feel about this? What are some good points and bad points to this service provided by some companies in your mind? 6) Answer in one paragraph and using the video provided to answer the following: There is rumor that humans are being cloned in other areas of the world. What ethical considerations can you think of that could be a problem with this type of medical experimentation? What is your opinion?
