Rebecca wants to know the density of a penny. She knows that the mass of a penny is 3 grams. Next, she needs to measure the volume. To do that, she uses a graduated cylinder to find the displacement of water after the penny is dropped into the cylinder. Her results are provided. Volume of Water Before the Penny Was Dropped In: 30 mL
Volume of Water After the Penny Was Dropped In: 31.5 mL

Based on the provided data, Rebecca can conclude that the density of the penny is which of the following?

your answer is "the 1950's"

i am positive it is c. condensing but i may be wrong

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 offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
