Solutions
Expert Solution
Intensity of orange/brown/red color of reduced DNS is proportionally related to the amount of maltose in solution.
DNS is used to study the enzymatic activity of amylase, which breaks starch into maltose. Higher amylase activity produces more amount of maltose, which reduces 3, 5-dinitrosalicylic acid (DNS), which is yellow in color, to 3-amino, 5-nitrosalicylic acid (commonly termed "reduced DNS"), which may be orange, brown or red depending on the concentration of maltose.

The candy Reese's Pieces comes in three different
colors: orange, yellow, and brown. The target color distribution is
45% of the pieces orange. 27.5% yellow, and 27.5% brown. A random
sample of Reese's Pieces packages contained 400 pieces
having the following color distribution: 162 were orange, 117
yellow, and 121 brown.
Test the hypothesis that Reese's Pieces is meeting its
target color distribution. Use α = .01 (define the population
parameter(s) in H0). (Which hypothesis is your
claim)

Small populations of flies that had three genotypes/phenotypes
for eye color (red,orange, and white) were observed over several
generations under laboratory controlled conditions (all the same
for the samples). Over time the diversity in many of the
populations changed from flies of three colors to flies of one
color, inevitably red or white, but never the heterozygous
condition of orange. These observations suggest a. Natural
Selection, red or white eyes were more adaptive. b. Sexual
Selection, the females were not...

Erioglucine is a bluecolored dye that absorbs its complementary
color, red, in aqueous solution around 645 nm. Unfortunately, the
local distilled water supply is consistently contaminated with a
trace amount of a metal cation that also absorbs 645 nm light.
Suppose then, a control sample of 0.0552 M erioglucine (aq; same
water supply) has an absorbance of 0.331 and that a distilled water
sample in a similar cuvette has an absorbance of 0.019. Determine
the concentration of an erioglucine (aq)...
