Dr. Lange discovers a colony of bacteria living in an
extremely acidic environment. While observing the colony,
she finds that the bacteria are autotrophs.

Which best describes the bacteria discovered by the
scientist?

They are probably archaebacteria because they are
autotrophs.
They are probably eubacteria because they are
autotrophs.
They are probably eubacteria because the colony lives in
an extreme environment.
They are probably archaebacteria because the colony
lives in an extreme environment.

answer: the answer is b

hey, what do you need . just post the question and i may be able to you : )

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.
