If a hemoglobin standard of 20 g/dL returns an absorbance of 1.000 when assessed with a spectrophotometer at 540 nm, then what is the approximate hemoglobin concentration of a solution with an As 40 0,600? To receive credit, report the numeric value and the unit of measure. [2 pt: G4.4)

5.17 Figure P 5.2 shows the equivalent circuit of a biopotential electrode. A pair of these electrodes are tested in a beaker of physiological saline solution.The test consists of measuring the magnitude of the impedance between the electrodes as a function of frequency via low-level sinusoidal excitation so that the impedances are not affected by the current crossing the electrode-electrolyte interface. The impedance of the saline solution is small enough to be neglected.Sketch a Bode plot (log of impedance magnitude versus log of frequency) of the impedance between the electrodes over a frequency range of 1 to 100,000 Hz.

Aristapedia is a lethal allele that is also dominant. Individuals with this trait must be heterozygous (Aa) because the homozygous condition (AA) is lethal. This is not a sex-linked trait. Wild-type flies do not carry the allele for aristopedia (aa). 1. Predict what the outcome of a cross between a wild-type fly and one with aristopedia. Show the punnett square to illustrate your reasoning.

2. The pedigree below the inheritance of widow's peak. a. Is Widow's peak a dominant or a recessive trait? Explain your answer. b. Assign genotypes to the shaded and unshaded symbols.

2. Choose a female from the offspring and mate it with a male that has vestigial wings and a black body(ggbb). Show a punnett square or a visual representation of the alleles involved in this cross to make a prediction about the offspring.

Exercise 4,3 had the user incubate the colorimetric reaction for at least 5 min at room temperature. How would an incubation of 2 min affect the absorbance measurements?(2 pt G4.5) *The absorbance measurements would not be affected. *A decreased incubation time would faisely increase the absorbance. *A decreased incubation time would falsely decrease the absorbance.

What negative control was used for the standard curve in Exercise 4.22 [2 pt: G4.5) *0.125% starch solution *Sweet potato extract *white potato extract *deionized water

5.11 A metal micro electrode has a tip that can be modeled as being cylindrical.The metal itself is 1 um in diameter, and the tip region is 3 mm long. The metal has a resistivity of 1.2 x 10- N.cm and is coated over its circumference with an insulation material 0.2 um thick. The insulation material has a relative dielectric constant of 1.67. Only the base of the cylinder is free of insulation. a. What is the resistance associated with the tip of this microelectode? b. What is the area of the surface of the electrode that contacts the electrolytic solution within the cell? The resistance associated with the electrode-electrolyte interface of this material is 103 0 for 1 cm?. What is the resistance due to this micro electrode's contact with the electrolyte? c. What is the capacitance associated with the tip of the microelectrode when the capacitance at the interface of the electrode-electrolytic solution are neglected? d. Draw an approximate equivalent circuit for the tip portion of this microelectrode. e. At what frequencies do you expect to see distortions when the electrode is connected to an amplifier having a purely resistive input impedance of 10 MO? You may assume that the reference electrode has an impedance low enough so that it will not enter into the answer to this question. If the amplifier's input impedance is raised to 100 MN, how does this affect the

Spectrophotometric measurements require the use of clean cuvettes. How would a failure to remove fingerprints, oil and dirt from the cuvette affect the absorbance measurements? [2 pt; G4.5) *the absorbance values would not be affected *the absorbance values would be falsely increased *the absorbance values would be falsely decreased
