In labrado for one gene influence the color of the pigment in the hair (b is black and b is chocolate brown). the all r retrievers, coat color is determined by the interaction between two genes. the alleles eles for a second gene influence whether the pigment is deposited in the hair (e is full deposition d e is reduced deposition). yellow labrador retrievers are homozygous recessive for the second gene. a female chocolate lab (bbee) is crossed with a male black lab (bbee). what are the possible genotypes and phenotypes of the puppies? (use a punnett square to show the results.)

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.

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.

carbon traps heat so more of it makes it hotter causing global warming. during the ice age carbon levels in the atmosphere were low so it got very cold. so the common things between them is carbon levels in the atmosphere.
