Summary Introduction
To draw: The graph depicting the distribution of rods and cones in the retina.
Concept introduction: A typical retina of a mammal contains two types of photoreceptors, the rods and the cones. The rods are present in larger number than cones. There are 125 million rods and 6 million cones in a typical retina. The cones of the retina mediate color vision while the rods mediate vision during night.

Assume that you have an “X” solution that you do not know its concentration. But you have other X solutions with known concentrations and you know X solution absorbs maximum light at 575 nm. To calculate the unknown solution concentration, you have done some spectrophotometric measurements and obtained data given below.
Prepare a standard curve by using the absorbance of known concentrations (Hint: you can learn how to prepare a standard curve by using Excell from youtube).

- Identify the tagma indicated by the arrow.arrow_forwardAn investigation was set up to determine the effect of various surfaces on the amount of time it takes a snail to move between two points. A ramp was made, covered with a piece of glass, and placed on a table at a 25-degree angle. Two lines, 15 centimeters apart, were drawn on the glass. A snail was placed on the upper line, and a stopwatch was used to measure the 2) amount of time it took the snail to move to the lower line. The results were recorded in a data table. The investigation was repeated using sandpaper and cardboard on the surface of the ramp. What must be done to show that the results of this investigation are valid? A) The ramp must be replaced with a log found in the habitat of the snail. B) The angle of the ramp must be increased to 35 degrees. C) The investigation must be repeated several times. D) The times in the data table must be averaged.arrow_forwardConsider a bi convex lens with radius of curvatures |R1| = 30 mm and |R2| = 180 mm, ct = 5 mm and glass is N-BK7.

Using a spectrophotometer the student observed that S7 converts to a colorless molecule in the presence of malaria parasite called Plasmodium falciparum. To study the rate of reaction, the student recorded the absorbance/amount of S7 at a wavelength of 570 nm. The results are summarized in the table below: Time (s) Absorbance/Amount of S7 0.80 0.63 10 0.50 15 0.40 20 О.32 25 0.25 30 0.20 Determine the half-life of S7.
