a.
To explain: To identify the organism based on the observation.
Introduction: A 35-year-old female underwent abdominal surgery that involves bowel resection. Following the surgery, she was maintained on a course of intravenous (IV) broad-spectrum antibiotics. She had a fever after three days of the surgery and she also complains of vaginal discomfort. The blood cultures showed the presence of an ovoid cell that reproduces by budding.
b.
To explain: whether the identified organism is a part of normal flora in humans.
Introduction: Candida albicans is an opportunistic fungal pathogen. It is the most common fungal species that causes human diseases. It is responsible for causing candidiasis in humans. It causes three types of candidiasis, namely oropharyngeal candidiasis, vulvovaginal candidiasis, and invasive candidiasis.
c.
To explain: The way in which the treatment with broad-spectrum antibiotics predisposes the patient to infection with the organism identified.
Introduction: Antibiotics are chemical substances produced by microorganisms that act against other microorganisms. They are used to treat bacterial infections. Broad-spectrum antibiotics are those that act against a large number of disease-causing bacteria.
d.
To compare: The effectiveness of hand washing with water, soap, and surgical scrubbing.
Introduction: Human hands come in contact with various objects and surfaces that are contaminated with a wide variety of microbes. Inadequate hand washing is a major transmission vehicle of diseases and infections.

You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait? (4 pts)? 12pt v R Paragraph V BIU A श्र > Barrow_forwardThere are many differences between DNA replication happening during mitosis in a Douglas fir tree growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence Repeat. Complete the following table that compares the two DNA replication events in terms of the primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value for the number of copies of the template DNA after one S phase in one cell and after the lab has completed the PCR reaction.

- Use the Henderson-Hasselbalch equation for a propanoic acid solution (CH₂CH₂CO₂H, pK₁ = 4.874) to calculate the quotient [A-]/[HA] at three different pH values. pH = 4.479 [A-] [HA] [A-] pH = 4.874 [HA] = pH = 5.220 [A-] = [HA]arrow_forwardIn order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward9. Chicken combs in chickens is an example where you see interactions between genes. See potential genotypes and phenotypes below. Which genotype, when mated to a rose comb chicken, will produce progeny that are 50% walnut comb and 50% pea comb? walnut (RRPP) walnut (RrPP) pea (rrPP) walnut (RRPP) walnut (RrPp) pea (rrPp) rose rose single (RRPP) (Rrpp) (rrpp)arrow_forward
