During Mendel's second set of experiments, he allowed the F1 offspring from the first experiments to self-pollinate. Which of the following best describes
the results?
A. About 25% of the F2 offspring expressed a different version of the
studied trait than the parents had.
B. About 25% of the F2 offspring expressed the same version of the
studied trait as the parents had.
C. All the F2 offspring expressed the same version of the studied trait
as the parents had.
D. All the F2 offspring expressed a different version of the studied
trait than the parents had.

the answer to your question is:

c. complementary base-pairing

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

the answer is b.) hydrogen bonds between bases.

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
