Allisa [31]

Answer:

C. Document the number of honey-making bees per hive.

Explanation:

Among the given options, the only useful criteria towards the experimental design of honey production are to "document the number of honey-making bees per hive". We know that the increased number of animals would increase the workforce and thus increase the production of honey (direct relation). Therefore, this will give a direct assessment of honey production.

malfutka [58]

Answer:

of diffusion

Explanation:

Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.

Digiron [165]
<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+
<span>
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>
