1. In humans, the autosomal gene allowing us to see the color
blue (symbolized as B) is dominant over a
different version of the same gene (b) which causes us to be color
blind for this color. A person with
normal vision will have the genotype
A) Bb
B) BB or bb
C) BB
D) BB or Bb
E) bb
2. Which of these cells can do meiosis in animals?
A) germ line cells
B) somatic cells
C) diploid cells...
a) Copper solutions are typically blue to blue green in color.
What color of light would they be expected to absorb in the
greatest amount?
Red
Violet
Blue
Green
b) Based on your answer to the
previous question (hopefully you have the correct answer), what
wavelength range would you expect to see the maximum absorption of
light (in the visible range)?
500 nm to 600 nm
400 nm to 500 nm
300 nm to 400 nm
600 nm to 700...
1) One method of producing drinkable water is to force seawater
through a membrane that does not allow the salt to pass through.
Such a process is called reverse osmosis (RO) and the membrane a
reverse osmosis membrane. A large reverse osmosis facility
continuously filters 2300 L of seawater per hour. The seawater
contains sodium chloride (NaCl) at a concentration of 1.4 M. Two
streams emerge from the RO facility: (1) a “brine” stream with a
sodium chloride concentration of...
In snorkeling a swimmer breathes by means of a tube that extends
above the water level. A) Why is the tube restricted to about 20
centimeters? That is, what is the acute danger in using a longer
tube? b) So under a certain depth people now scuba dive. When a
scuba diver is brought back to the water surface, why must the
diver wait at certain depths for set time intervals instead of
being brought up continuously?
Why would CuSO4 have a blue color after the iron reagent is
added? Yes, the answer is because it is absorbing the other colors
(the spectrophotometer), but WHAT is absorbing the other
colors?
(Done in an experiment about spectrophotometry)
What determines the trait we see, like color of eggs or
hair?
Why is it useful to have variation in a population?
Could this procedure be used to alter other traits?
In mice the allele for blue
coat color (B) pink coat
color (b). The allele for long
tail (T) is dominant of the allele for short
tail (t).
1) If alleles of the two genes Assort
Independently, what types of gametes will BbTt
mice produce? What is the expected frequency of each gamete among
all gametes produced?
Most people like the color blue; it is the favorite color of many
people. Do we like blue because we associate it with activities we
have enjoyed under a blue sky? Maybe we choose blue cars and blue
shirts because we are classically conditioned to respond favorable
to blue.
What is the unconditioned stimulus?
What is the unconditioned response?
What is the conditioned stimulus?
What is the conditioned response?
Why
do we like blue cars and blue shirts?
Many people...
A study of the effect of exposure to color (red or blue) on the
ability to solve puzzles used 42 subjects. Half the subjects (21)
were asked to solve a series of puzzles while in a red-colored
environment. The other half were asked to solve the same series of
puzzles while in a bluecolored environment. The time taken to solve
the puzzles was recorded for each subject. Due to the association
of urgency with red, researchers believe those exposed to...
