The validity of the hypothesis cannot be confirmed or refuted from only one experiment. By using a series of experiments, the human error or measurement error is reduced to a minimum. Furthermore, more than one factor can be used to determine the validity of the hypothesis.
I will respond to this student that the experiment needs to be repeated multiple times before a conclusion can be drawn! Also, the data will refute or confirm the validity of the hypothesis and not the researcher's own opinion/rational.

The correct answer is that "<span>RNA polymerase binds to the promoter, which precedes the gene only on the template strand of DNA."
A gene is best described as </span>a chain<span> of DNA or RNA which codes for a molecule that has a </span>characteristic<span>. </span>for the duration of<span> gene expression, the DNA is first duplicated into RNA. The RNA </span>can be immediately practical<span> or be the intermediate template for a protein that </span>plays<span> a </span>characteristic<span>. The transmission of genes to an organism's offspring is </span>the idea<span> of the inheritance of phenotypic </span>traits<span>.</span>
Humans are more closely related to hogs than hogs are to guinea pigs.
Explanation:
The difference in the amino acid sequence of a protein is used to know the relation between organism i.e. how closely they are related.
It is known that proteins are the result of DNA sequence ie genes of the organism.
The gene or protein is compared between organisms to understand the evolutionary evidence and similarities between them.
The less is the difference the more is the two organisms closely related as in the case of hog and human which have only 1 amino acid difference in their insulin enzyme. While guinea pig is having a difference of 17 amino acids so it is expected to be distantly related.
These relations helps the scientist to resolve the issues of crisis say insulin. They zero out the possibility of extracting the enzyme genes of possible organism and increase the yield.
<span>7. which, if any, of the blood samples tested cna the patient with type b+ blood receive? explain why.
It can't be answered because you didn't put the sample test result
8. explain how you were able to use your knowledge of how different types of blood react with anti-a, anti-b, and anti Rh antibodies to determine the blood types of the four samples.
If the blood react with anti-a, then the blood must not have A antigen
</span>If the blood react with anti-b, then the blood must not have B antigen
If the blood react with anti Rh, then the blood must not have Rh antigen
Based on the antigen, you can conclude the result as:
react with anti A= blood type B
react with anti B= blood type A
react with anti A and anti B= blood type O
react with anti Rh= Rh-
not react with anti Rh= Rh+

9. if a person has type a blood, he or she would have antibodies for what blood type?
Type A blood has antigen A. So that person should not have anti-A antigens.
The person should have anti-B antibodies because it was a foreign object to him. Depends on the Rhesus type, he can have Rh antibodies too.
10. why is type o negative blood known as the universal donor? why is o positive not a universal donor?
Type O blood doesn't have antigen-A or antigen-B. That means the blood cells won't trigger any reaction on Type A, B, AB, or O blood. Negative rhesus also means that the blood is safe for Rhesus negative or Rhesus positive type.
Positive O blood type has rhesus antigen, so it will trigger a reaction in Rhesus negative type. </span>
