Scientists compare two different plant species. In species A, the leaf color is controlled by two alleles. In species B, leaf color is controlled by three alleles. How will these two plants be different?A. Species B will have fewer genotypes.
B. Species B will have fewer phenotypes.
C. Species A will have more genotypes.
D. Species A will have fewer phenotypes.

Answers

Answer 1
Answer: The answer is D. Species A will have fewer phenotypes.
Alleles are alternative forms of a gene. In species A, the leaf color is controlled by two alleles, for example, P and Q. They will have three possible genotypes - PP, PQ, and QQ. Three different genotypes give maximum three phenotypes.In species B, leaf color is controlled by three alleles, for example, L, M, and N. They will have six different genotypes - LL, LM, LN, MM, MN, and NN. Six different genotypes give maximum 6 phenotypes.

1) People occasionally poison themselves with carbon monoxide by building a charcoal fire in an enclosed area. Assuming help arrives in time, what would be the most effective treatment: Placing the victim outdoors in fresh air, or administering pure oxygen? Explain your answer.

Answers

Answer:

Administering pure oxygen is a more effective treatment to carbon monoxide poisoning than just placing the victim outside.

Explanation:

It takes a large amount of oxygen to get rid of carbon monoxide from the body, and there is only 20.95% of oxygen in air. Therefore, 100% pure oxygen is required to be administered for a few hours before the carbon monoxide can be removed from the bloodstream.

Carbon Monoxide gets attached to the hemoglobin in the blood, but does not benefit the body in any way.
