The Chi Square value for this cross is 0.086. The degrees of freedom is 1 and using a p value of 0.05, it can be proved that there is no significant difference between the observed distribution and the theoretical distribution. Thus, we accept the results.
To test if the chickens lacked thiamine the scientist could test the blood concentration of thiamine in the chickens on a future study, unless blood samples were taken during the original study.
In any future studies, the same experiment would need to be done but with this added measurement on both the control group and the test subjects.
It’s Sigmoid Phenomenon aka D
It took the test
Answer:
<em>The correct option is B) DNA fragments are negatively charged.</em>
Explanation:
The backbone of the DNA is made up of sugar and phosphates. The phosphates present in the backbone of the DNA are the main reason for the DNA to be negatively charged. The negative charge of the DNA allows different DNA fragments to separate by gel electrophoresis depending on their charge/mass ratio. The smaller DNA fragments will move faster towards the positive end of the gel as compared to the larger fragments and hence they will separate.
Answer:
I am pretty sure its True
