This is scientifically significant because it shows that the presence of x-gal does not

2. When seeds are germinated, it is probable that they would consume more oxygen. This is
because germinated seeds need more ATP. There is also cellular respiration, which produces

Are any deviations from the expected phenotypic ratio of the F2 generation within the
limits expected by chance?
To answer this question, statistically analyze the data using the Chi-square analysis.
Calculate the Chi-square statistic for the F2 generatio
Since there is only one type of plasmid (pBLU), the LB/AMP (+) plate and the
LB/AMP/X-gal (+) plate have similar genotypes even though they appear phenotypically
different because the plasmids that they took up are identical.
Any bacteria that look blue m
It is necessary to isolate the P generation females from males because female fruit flies
can store sperm to fertilize their eggs later.
In order to determine genetic relationships, it is necessary to control the parental cross.
Isolating the females of t
LB/Amp+ is the negative control because theory suggests that the lack of x-gal will result
in white colonies but will not affect bacterial growth.
This is scientifically significant because it is used to show that x-gal is the product that
causes blue col
The decomposition of hydrogen peroxide happens spontaneously; additionally, direct
exposure to sunlight speeds up the process of decomposition.
Additionally, a warmer temperature will also increase the rate of decomposition.
Ordinarily, this would not be
One reason that high blood pressure is a health concern is because the heart has to work
harder to pump the blood, causing an increased risk of heart attacks.
The LB- plate as is described below is the negative control because ampicillin an
Temperature does not affect the heart rate of endotherms significantly because
endotherms regulate their internal processes regardless of temperature.
A third reason is that if blood pressure is high enough the heart may not be able to pump
Human blood pressure and heart rate differ when measured in a reclining position versus
a standing position because the heart must do more work when a human is in a standing
When a human is standing, his heart must pump blood to the brain and ar
There were several types of plasmids available.
There was only one type of plasmid that the bacteria could take up, and this plasmid had
both the ampr gene and the lacz gene.
