Answer:
The model proposed by Jacob and Monod predicted that a specific DNA sequence near the transcription start site of the lac operon is a binding site for lac repressor. ... In this system, separate mutations in both copies of lacI in a given cell are required to generate a lacI− constitutive mutant, a low-probability event.

In normal healthy adult, Calculate the Gain of control system of cold temperature if A cold exposure is expected to bring the body temperature down to 20°C but brings it down only to 36.5°C?
Answer:
Increased intraluminal pressure may help maintain vasodilation in a dependent arm even after hypothermia triggers centrally mediated thermoregulatory vasoconstriction. We therefore tested the hypotheses that the threshold (triggering core temperature) and gain (increase in vasoconstriction per degree centigrade) of cold-induced vasoconstriction is reduced in the dependent arm during anesthesia. Anesthesia was maintained with 0.4 minimum alveolar anesthetic concentration of desflurane in 10 volunteers in the left-lateral position. Mean skin temperature was reduced to 31 degrees C to decrease core body temperature. Fingertip blood flow in both arms was measured, as was core body temperature. The vasoconstriction threshold was slightly, but significantly, less in the dependent arm (36.2 degrees C +/- 0.3 degrees C, mean +/- SD) than in the upper arm (36.5 degrees C +/- 0.3 degrees C). However, the gain of vasoconstriction in the dependent arm was 2.3-fold greater than in the upper arm. Consequently, intense vasoconstriction (i.e., a fingertip blood flow of 0.15 mL/min) occurred at similar core temperatures. In the lateral position, the vasoconstriction threshold was reduced in the dependent arm; however, gain was also increased in the dependent arm. The thermoregulatory system may thus recognize that hydrostatic forces reduce the vasoconstriction threshold and may compensate by sufficiently augmenting gain.
Implications: The threshold for cold-induced vasoconstriction is reduced in the dependent arm, but the gain of vasoconstriction is increased. Consequently, the core temperature triggering intense vasoconstriction was similar in each arm, suggesting that the thermoregulatory system compensates for the hydrostatic effects of the lateral position.
As the office manager you come into contact with various drug representatives that provide you your office with free samples. It is important to keep them organized in a locker drawer. What is the most efficient way to organize the samples ?
Answer:
Keep the samples in bins for each specific sample, label each bin so that the samples don't get mixed up.

Scenario:
Assume you are a pharmacy assistant in a nursing home, screening patients for contraindications and drug interactions. What is the
potential drug problem--and its solution--for each of the following cases?
a. Patient A has hypertension. He has been prescribed hydrocortisone injections for severe bursitis.
b. Patient B is diabetic. She has been prescribed prednisolone for osteoarthritis.
Please use the textbook (chapter 36) as a reference for this discussion. A maximum of 10 points will be given for this assignment.
Answer:
a- hydrocortisone cause hypertension by renin-angiotensin-aldosterone.we treate that by diuretics
b-prednisolone cause increase blood sugar by increasing resistance liver for insulin. we can treat by cream or reduce dose

Assisting in Pulmonary and Cardiology Medicine and Performing EKGs: Professionalism Assignment
Predict the outcome from this scenario and validate the course of action. Identify unprofessional behavior and establish preventive measures.
A male medical assistant volunteered to perform an EKG on an 18-year-old female. The parents of the patient remained in the waiting room area and no other staff attendees were in the exam room assisting the MA. The patient was instructed to remove her clothing from the waist up and was not given a drape to cover herself. He explained that “modesty” does not apply in healthcare or medicine. The patient appeared to be nervous but under the impression that this was normal practice for an EKG.
Precordial electrodes were placed correctly and a tracing was initiated in an air conditioned room. Although the patient was anxious, she now was cold and started shivering. Somatic tremor artifacts were indicated and present on the EKG tracing. The artifacts were not resolved, corrected, or prevented. The MA dismissed the patient and forwarded the tracing for its interpretation to the provider.
Answer:
Explanation:
Sooo I'm literally in high school but I wanna be a doctor so I'm gonna see if I can answer this with some course of knowledge. So I'm assuming that since hes a male medical assistant, and the girl is 18, he is allowed to preform an EKG? I also know that if he has proper training he can preform an EKG. It seems kinda weird that no other staff attendees were in the exam room, and how she was instructed to remove her clothing and was obviously not comfortable. He should have asked the girl if she wanted someone else in the room with her, such as a female medical assistant or even just another female. I think he should have also given her something to drape over herself, once the pads were in place. Maybe since she didn't have a drape over her she became cold, and anxious. That's all I can really answer:)
