can someone help me please imstuck on these three questions???
#8 Would altering the light wavelength of the spectrophotometer have any bearing on the results obtained?
Would altering the light wavelength of the spectrophotometer have any bearing on the results obtained?
No, the wavelength used on the spectrophotometer is not important the way this experiment was set up.
No, this experiment was looking at amounts of glucose in liquids, so the wavelength of light used is irrelevant.
Yes, the wavelength was important when obtaining the glucose standard curve, but not when measuring the blood samples.
Yes, the enzyme color reagent used in all the tubes absorbs maximally at a certain wavelength, so usinga different wavelength would yield misleading results.
#9In the experiment with hormone replacement therapy, if a hormone such as testosterone were used in place of estrogen, which of the following effects would be seen?
In the experiment with hormone replacement therapy, if a hormone such as testosterone were used in place of estrogen, which of the following effects would be seen?
The female rat would begin to take on male characteristics such as increased muscle mass, increased sex-drive, etc.
Substituting testosterone for estrogen would lead to erroneous results since VBD would decrease.
VBD would be unaffected since testosterone would not bind to the estrogen receptors involved with maintaining normal bone density in women.
None of the above effects accurately describes what would occur.
#12 Using the respirometer-manometer, you observed the amount of oxygen being used by animals in a closed chamber. What happened to the carbon dioxide the animals produced while in the chamber?
Using the respirometer-manometer, you observed the amount of oxygen being used by animals in a closed chamber. What happened to the carbon dioxide the animals produced while in the chamber?
The animals did not produce a significant amount of carbon dioxide.
It collected inside the manometer causing the fluid level to change.
It was absorbed by soda lime at the bottom of the chamber.
It was allowed to collect inside the chamber since oxygen was the only gas that needed to be measured.
