1. Why is it possible to use density as a way to identify and determine purity...
Answer the following in the most detailed way possible Identify the substances contained in plaque; how plaque builds-up in blood vessels. and give one dietary suggestion to reduce plaque build-up. Choose one un-programmed theory, and discuss how it could be used to create helpful guidelines advice for health promotion behavior for older adults. Identify and describe how two markers of frailty are measured. Then, describe a health-promotion intervention with older adults that could help to prevent that physical sign. First,...
3.) Determine, if possible, a nontrivial homomorphism between the indicated groups or explain why no such homomorphism exists. a) 0 : Z10 → Zo b) T: S3 Z3
MUST use A times indetity matrix method to prove it is not possible and explain why it is ntot possible by looking the matrix turns out DO NOT use determine method 4-4 =0 is not possible!!! Let Find A-1 if possible. If A- does not e determine why
Why is it possible to identify many protozoa without the need for biochemical and serological testing? What are some of the beneficial protozoa? What chemical substance is present in viruses, but lacking in prions? Do prions replicate the way viruses do?
can you please explain this answer to me in the simplest way possible and why that is the answer thank you! 61. Which set of quantum numbers cannot specify an orbital? a. n = 2,1 = 1, m, = -1 b. n = 3,1 = 2, m = 0 c. n = 3,1 = 3, mi = 2 d. n = 4,1 = 3, m = 0
Solve for the variable. Identify any extraneous solutions. If no solution exists, explain why. Solve for y: Solve for y: x=y=3 x=> -y+2 y-3
1. Explain why a buffer solution should be used to prepare for the fluorescein solution. -2. Indicate the wavelength of a shoulder in an absorption band. Explain why a shoulder exists in the absorption band. 23. Calculate the mole ratio of dianion to monoanion of fluorescein at pH 7.4 (use the Handerson-Hasselbalch equation to calculate the ratio). Calculate the absorbance ratio of the dianion to monoanion from the absorption spectrum. Can you claim that since the absorbance is proportional to...
I appreciate the help. Thanks you! Week 1 Post-Lab Summary Questions and Activities 1. Why did you use a primary standard like KHP and not another aqueous solution (e.g. HCI) to determine the concentration of NaOH? 2. What is the average concentration of your standardized NaOH solution? Show the calculations for one of the titrations. Include any data and data tables used to calculate the concentration. 3. What are 2 possible sources of error associated with the standardization of NaOH?...
A grass seed company conducts a study to determine the relationship between the density of seeds planted (in pounds per 500 sq ft) and the quality of the resulting lawn. Eight similar plots of land are selected and each is planted with a particular density of seed. One month later the quality of each lawn is rated on a scale of 0 to 100. The regression equation is given below, where x denotes seed density, and y denotes lawn quality....
