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.

This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. • How might the location and slope of the O2 line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO2 line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?arrow_forward
- How much ATP will be produced during the following metabolic scenario: Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid. Recall that when glycerol breaks down to Glyceraldehyde-3-phosphate it costs one ATP but your get an extra FADH2. Every two carbons of a fatty acid break down to one acetyl-CoA. Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.arrow_forwardIf a bacterium using aerobic respiration was to degrade one small protein molecule into 8 molecules of pyruvic acid, how many ATP would that cell make? Assume there is no other carbon source. Units cannot be entered in this style of question but the units of your answer should be in molecules of ATP.arrow_forwardIf a bacterium using aerobic respiration was to degrade a 30 mM solution of citric acid, how many ATP would that cell make?

Additionally, the serine was found to constitute 0.35% (by weight) of this beta-lactamase enzyme. Using this, calculate the molecular weight of this enzyme and estimate the number of amino acids present in the polypeptide.arrow_forwardBased on your results from the Mannitol Salt Agar (MSA) media, which of your bacteria were mannitol fermenters and which were not mannitol fermenters?arrow_forward

The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?arrow_forwardHow do I determine the inhertiance pattern from the pedigree diagram?arrow_forward
