Explain in detail how (1) temperature, (2) nutrient level, 3) oxygen level, and 4) the antibiotic chloramphenicol affect bacteria. It is not sufficient to say that the condition slows or speeds up growth, but clearly indicate the underlying physiological reason why each condition would decrease or increase growth. What impact does each condition have on bacterial cells physiologically?

You have available the buffer ADA: disodium salt a) using the buffer, explain, in some detail including numerical calculations, how to prepare 500ml of a buffer with a pH=6.50 and a total concentration of 50.0mM for the acid and conjugate base. b) What volume of either the NaOH or HCl solutions would you need to add to change the pHof 100mL of the buffer to pH 6.00

A vertical infinite wire along the z-axis has two symmetries: One is a rotational symmetry around the z-axis while the other is a translational symmetry along the z-axis. Describe the symmetries of a) a sphere, b) an infinite plane, c) a circular plate, d) a finite length rod with circular cross section, and e) a finite length bar with a square cross section.

Please explain process.

Define an acid, base, and salt as they apply to chemistry and State three examples each of acids, bases, and salts commonly used in therapeutic processes.

From the examples you state, select one acid, one base, and one salt and describe specifically how and where they are used in therapeutic processes

research on buffered aspirin. On the basis of your research, respond to the following: Define a buffer and explain how a buffer works. Analyze and explain the buffer system in buffered aspirin (carboxylic acid).

Consider Mary's experiment regarding whether learning of 6th graders on a math lesson is affected by background noise level. Mary has collected her data. What is the null hypothesis for her study? What is the alternative hypothesis for her study? What are the assumptions that must be met about her data before she can correctly use an independent t-test to test the hypotheses? Why? How would she see if her data met these assumptions? How much room does she have to violate any of these assumptions and still get accurate results from the t-test? Explain and support your answers.

Mary's Study: Mary is planning a study to see if learning of 6th graders on a math lesson is affected by background noise level. She wants to use a t-test for independent groups to analyze her results.

make a plot of the data in the table below , plot position versus time time squared (t² ). make sure to label your graph properly.( Y axis title with units, X axis title with unit, title of the graph with equation , major tick marks. use data to plot the graph manually. use proper scal

A) what do you notice about the shape of the plot this time?explain

b) what is the slope of the line in this plot equal to ( not a number)

c) determine the slope of the graph by determing the least Squares best fit line to the data. what is "g" determined from slope?

Mr Adam’s daily income is $20 per day. He spends all of the income on buying apples and oranges. The
prices are: $ 2 per apple and $ 4 per orange.
g) Using the given scenario discuss the concept of maximizing utility in detail. How is the concept of
maximizing utility related to the definition of microeconomics?
Let’s assume, Mr Adam is consuming 4 apples and 3 oranges per day. The marginal utility from apples is
10 utils and marginal utility from oranges is 12 utils.
h) Is Mr Adam maximizing utility? Explain briefly.
i) If Mr Adam is not maximizing utility, then how can he maximize utility? Explain in detail.

Critical Thinking questions:

1.   A traveler, in excellent physical condition, is takin a trip to Andes Mountain in South America. Once climbing up to the high, she fined herself breathing rapidly. What happen to her and why? Explain.

2.   Upon placement of endotracheal tube (ET) into anaesthetized patient, the resident noticed that the air sounds were coming from epigastric region rather than from the lungs. What went wrong?

3.   What is the difference between pneumonia and pneumonitis?

4.   What is bronchogenic carcinoma? Provide detailed explanation.

Case Study:

25-years old college student as involved in a very heavy car accident. Arriving at the scene, the EMT personnel observe that: she was cyanotic and apneic (not breathing); her pulse was fast and thread, her head was tilt at peculiar angle as if she is having fracture at C₂ vertebra.

Questions:

1.   What is the connection between her head position and her cessation of breathing?

2.   Explain to your best her cyanosis.

3.   What is pneumothorax and why would in cause of R lung to collapse? Why not the left one?

4.   Doctor inserts a chest tube into the R intrapleural cavity and hooks it up to suction. How might this alleviate the pneumothorax?

Case Study 1:

A young 27-yeals old male patient had surgery on his R hand. The complete blood count (CBC) done indicates: very low total leukocyte count and low proportion of lymphocytes. One day after surgery, he complains of pain on his R injured ring finger. Observations indicates: the finger and dorsum are red, warm, and edematous, red streaks radiating proximally on the R forearm. High dosage of antibiotics was prescribed, and personnel was advised to have gloves and gown for his protection (known as reverse protection).

Questions:

1.   What is the connection between low level of lymphocytes, antibiotic treatment and reverse isolation? Why is important for him NOT to move his affected arm?

2.   Provide the best statement that explains the presence of red streaks in his forearm.

3.   Do you predict that his recovery will be uneventful or problematic? Why?

Case Study 2:

Mr. Smith is 52-yeaars old patient diagnosed 18 years ago with aggressive form of multiple sclerosis (MS). Back to the hospital, his doctor offer him one. Drug that will release steam cells from his bone marrow (collected from his blood), two. Antibodies against his T-lymphocytes. These procedures were offer to him in order to avoid problems such as transplant rejection.

Questions:

1.   What type of transplanted organ (aka graft) would it be if he receive someone bone marrow? On the other hand, what type of graft would be if he receive his own bone marrow?

2.   What are MHC proteins (class I or class II and what is the difference between the two classes)?

The nurse explain to Mr. Smith that a bone marrow transplant from another donor could result in destroying his own immune cells. Provide your best explanation for this statement
