To ensure that the plant was kept at a constant temperature at each light intensity in this experiment: Select one or more: a. the temperature of the room was adjusted to keep the tube of Elodea submerged in water at a constant temperature with a thermometer inside the tube b. the tube containing Elodea submerged in water was surrounded by light on all sides with a thermometer inside the tube c. the tube containing Elodea submerged in water was placed in a water bath with a thermometer in the water bath

when viewing an organism under the 40x objective lens, you estimate that 6 organims could fit across the DFV if they were laid end to end and 20 could fit if stacked side by side. What is the length and width of this organism in micra?

Please answer this question If ABG sample is not properly iced, what effect will this have on the results?

In disc diffusion studies, where will the lowest concentration of the tested chemical be in the agar plate? in the agar directly below the disc O in the agar halfway between the disc and the petri dish wall O in the agar furthest away from the disc the cehmical is equally distributed throughout the agar

The experiment file says "Fill a cuvette with water and blank the spectrophotometer." What are we doing when we do this? Why is this step important

In an electrochemical cell, Q = 0.00025 and K = 0.70. What can you conclude about Ecell and E°cell?     Ecell is positive and E°cell is positive     Ecell is negative and E°cell is positive     Ecell is negative and E°cell is negative     Ecell is positive and E°cell is negative

On the graph that relates absorbance to flavin concentration, draw a horizontal line that starts at the point on the y-axis that corresponds to the absorbance of your unknown sample and ends at the curve you drew through your data points . Next draw a vertical line that starts at the point where the horizontal line intersected the curve and ends at the x-axis. The point where this vertical line intersects the x-axis corresponds to the concentration of flavin in your unknown sample. What was the letter on the tube with your unknown sample? What is the concentration of the flavin in your unknown

Suppose you did not observe a distinctly different image with the phase objective. What might this mean?
