Which of the following is used to bring an image into focus when using a compound light
microscope? - ANS condenser adjustment knob
What distinguishes dense irregular connective tissue from dense regular connective tissue? -
ANS it contains fibroblasts whereas dense regular connective tissue contains chondrocytes
A neuron consists of which of the following components? - ANS axon; cell body; dendrites
What will indicate a positive test for the presence of glucose in samples? - ANS yellow-golden
brown color
What is the relationship between the protein level in a sample and the color in the sample after
adding the appropriate indicator reagent to the sample? - ANS the higher the protein level,
the deeper the color in the sample
What will indicate a positive test for the presence of protein in samples? - ANS blue color
Which solution will be used to detect protein in samples? - ANS Bradford reagent
Specifically, how will metabolic rate be defined in this lab? - ANS as the amount of carbon
dioxide produced per unit body mass per hour

, If an absorbance value of 0.53 were obtained for a sample, which of the following would be
closest to the solute concentration in the sample? Use the regression equation below to
determine the solute concentration. y = 0.0125x - 0.02 - ANS 44 mg/dL
Which of the following represents the correct sequence of steps that must be performed when
using a spectrophotometer? - ANS set the wavelength-->insert blank-->blank the
spectrophotometer-->insert sample
How many "stops" do you encounter when you depress the plunger on a micropipette? -
ANS two
The following information is stamped on serological pipettes that are used in this course: "1 mL
in 1/100". What is the smallest volume that can be accurately delivered using this pipette? -
ANS 0.01 mL
When you determined metabolic rate of red flour beetles, you used a respirometry chamber
(vial) that contained beetles and soda lime pellets. What was the purpose of the soda lime
pellets? - ANS to absorb carbon dioxide that was produced by the beetles
If you were testing for protein level in hemolymph samples using the protein indicator that you
used in this lab, which of the following would indicate that one sample had a higher protein
level than another? - ANS the sample with the higher protein level would appear a darker
blue
