A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation
Answer:
The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.
Explanation:
As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.
Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.

Emilia Burton is an 18-year-old high school student who began to experience weight loss despite a ravenous appetite and resulting increased dietary intake. She has to make frequent trips to the bathroom to urinate and has difficulty concentrating on her work because of fatigue. She drinks large volumes of coffee to help with a constant dry mouth and to combat her fatigue. At a clinic appointment, it was noted that her weight has dropped from 140 lb to 128 Ib.
a) What is the probable diagnosis of this patient? What information from the above scenario would support your diagnosis?
b) What laboratory test(s) should be performed? Which result(s) would support your diagnosis? What immediate and long-term therapy will Emilia need to manage her disorder?
c) Emilia should be aware of the potential acute and long- term complications of her condition. What are they?
Answer:
A) The diagnosis is Diabetes mellitus which is based on the given symptoms that are weight loss, dry skin, fatigue, profuse urination, ravenous hunger all confirm diabetes.
B) Test for confirmation of diabetes Mellitus are-
Fasting plasma glucose test
Postprandial glucose test
Random plasma glucose test.
A1C test
If the test shows higher blood glucose it confirms the diagnosis
Immediate Treatment:-
Medication
Long term treatment:
Exercise controls the blood sugar
Diet should be healthy and should avoid high glucose options.
C) Acute and long term complications:-
Diabetic retinopathy
Diabetic foot

19. Fresh poultry should be rejected when:
A. It has been shipped in plastic wrap
B. It is slightly sticky to the touch
C. There is no discoloration
D. The receiving temperature is 38°F
Answer:
B
Explanation:
Fresh poultry should be rejected when the receiving temperature is 38°F. Therefore, option (D) is correct.
Poultry must be stored and transported at or below 40°F to guarantee food safety and inhibit the proliferation of harmful bacteria. Exposure to unsafe temperatures during storage or transportation can increase the risk of bacterial contamination and foodborne illness if the receiving temperature exceeds the threshold.
Indicators like plastic wrap during shipment, slight stickiness, or lack of discoloration do not necessarily imply safety concerns or spoilage with fresh poultry, as mentioned in the other options.

How do bacteria multiply again? Use the key terms genetic information, DNA, split in two, and exponential growth.
Answer:
Bacteria are asexual. This means that they are not like us, as they do not need a partner to multiply. A bacterium can become two bacteria all by itself. Then those two bacteria can each multiply again on their own and so, they become four bacteria.

A scientist runs an SDS-PAGE experiment two separate times on a protein with a molecular weight of 200 kD. For the first experiment he treats the protein with SDS only and for the second experiment he treats the protein with both SDS and a reducing agent. If the first gel yields one band showing a molecular weight of 200 kD and the second run yields one band showing a molecular weight of 25 kD, the researcher should conclude that
Answer:
This protein consists of 8 subunits of equal size linked by disulfide bonds
Explanation:
The sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) is a technique widely used in molecular biology laboratories to separate proteins with molecular weights between 5 and 250 kDa. SDS is an anionic detergent used to denature proteins before electrophoresis. SDS can denature proteins by altering non-covalent bonds such as hydrogen, hydrophobic and ionic interactions, but they cannot cleave disulfide bonds. In this case, reducing agents (e.g., β-mercaptoethanol or dithiothreitol) have been used to cleave disulfide bonds.

The phase of mitosis that is characterized by the disappearance of the nuclear membrane is
Answer:
Prometaphase (late prophase)
Explanation:
Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.
According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.
Which of the following is not a function of the bacterial cell wall?
A. Provide the cell with shape and rigidity
B. Prevent the cell from lysing
C. Protect the cell
D. Provide the cell with locomotion
Answer:
D
Explanation:
I believe locomotion would be the job of the flagellum
The correct option that is not a function of the bacterial cell wall is : ( D ) Provide the cell with locomotion
The Bacterial cell wall acts mainly as a protective cover to the cell of the bacterium, protecting the cell from lysing ( preventing the breakdown of the cell via osmotic pressure ). The cell wall also provides the cell with shape a and rigidity.
While The locomotion of the cell is not the responsibility of the cell wall but it is made possible by the flagellum.
Hence the non - function of a bacterial cell wall is providing the cell with locomotion.

Explanation:
Introspection is one of the many sleeping disorders experienced
by people with sleep apnea.
Select one:
True
False
Answer:
The statement is false.
Explanation:
Sleep apnea is a respiratory disease characterized by the fact that people who suffer from it habitually snore, have repeated stops of breathing (apneas) and drowsiness during the day. As a consequence, patients who suffer from it cannot rest well during the hours of sleep.The obstruction of breathing causes a decrease in oxygen levels in the body, the persistence of this lack of oxygen could cause pulmonary hypertension and a future right-sided heart failure or myocarditis. Introspection, on the other hand, is the immediate reflective capacity of the human mind to know its own states; it is not associated with sleep apnea.
