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 O b. There is no difference between the treatment and the placebo Oc. The difference between the treatment and the placebo is negative O d. There is a difference between the treatment and the placebo

Suppose you have two A-B-type exotoxins, A-B and A-B. A-B binds specifically to neurons and prevents a neuron-specific function, which is essential for nerve pulse transmission. A-B binds specifically to kidney cells and stops protein synthesis. A. What would a hybrid toxin, A-B, do to kidney cells? Provide your rationale. B. What would a hybrid toxin, A-B, do to kidney cells? Provide your rationale. C. What would a hybrid toxin, A-B, do to neurons? Provide your rationale. D. What would a hybrid toxin, A-B, do to neurons? Provide your rationale.
a. You have a test tube containing 5 ml of a solution of bacteriophages, and you would like to estimate the number of bacteriophages in the tube. Assuming the tube actually contains a total of 15 billion bacteriophages, design a serial dilution experiment that would allow you to estimate this number. Ideally, the final plaque-containing plates you count should contain more than 10 and fewer than 1000 plaques.
A biologist is studying a disease in corn that seems to be more common in cornfields in warmer weather. He is using three genotypes of corn and growing them in greenhouses under different temperatures (each genotype is grown under all temperatures) and measuring susceptibility to the disease. Draw a diagram with norms of reaction showing that the three genotypes respond differently to temperature in terms of disease susceptibility.
Discuss the importance of data when observing something like the outbreak of cholera or even the outbreak of COVID-19, when using the scientific method.
Assume you are studying the infection dynamics between a species of spider and a species of ringworm that infects the spider. You sequence the genomes of each species for 30 years and find that each of these species has evolved adaptations. Specifically, the spider has evolved immune system adaptations to remove the ringworm and the ringworm has evolved counter-adaptations to evade the spider's immune system. Surprisingly, you find that the ability of the ringworm to infect the spider has not changed over 30 years. The finding that infectiousness has not changed in 30 years would be in support of which of the following? a. The Red Queen Hypothesis b. Muller's Ratchet c. The Asexual Reproduction Benefit Hypothesis d. The Genetic Load Hypothesis
There are concerns about overuse and misuse of antibacterial drugs, and the association of these with increased antibiotic resisstance in bacteria. Of the following, which best explains this? Antibiotic exposure directly causes many of bacterial in a population to mutate and develop new antibiotic resistance traits. If antibiotic use occurs repeatedly in a person, the dosage of the drug needs to be increased to work in a patient’s system because he/she will develop physiological tolerance to the antibiotic. Exposure to an antibiotic causes bacteria to die or become stronger; stronger bacteria will be better able to cope with additional exposures to any antibiotic drug, eventually becoming immune to all antibiotics. Antibiotics kill susceptible cells and even a small number of existing resistant bacteria that survive will become the majority of the population that remains, leading to populations that are resistant to this drug.
1 mL of a bacteriophage suspension is mixed with 20 mL of a bacterial culture and 50% of the phages adsorb. We know that the bacteriophage suspension had a concentration of 1x1010 viruses per mL, and the bacterial culture had a concentration of 3x108 bacteria per mL. What fraction of the cells is multiple infected?
Please consider Figures, 10.28, and Table 10.2 (attached), which contain data that were collected by Delph and Lively, are redepicted from their paper that was published in 1989, and for which information is provided on pp. 391-383 in the textbook (pp. 385-388 in the 4TH edition textbook); assess the lowercase-Roman-numeral-labelled statements that appear immediately below; and click the uppercase-letter-labelled response that is presented below and conveys the most accurate information. i. Germinated pollen grains in Fuchsia excorticata grow tubes that extend from the stigma, through the style, to the ovary, where one sperm unites with one egg; this requires approximately 3 days. ii. Before a Fuchsia excorticata flower can detach from the tree, an abscission zone must be developed; this typically requires 1.5 days. iii. Colour change in Fuchsia excorticata probably evolved as an adaptation to the physiologically constraining 4.5 days that are required for fertilisation and abscission…
