Skulls of homo sapiens were found during an excavation. the skulls were preserved because the bodies were frozen. so, these fossils are ( 1 ) fossils.

( 1 ) a. mineralized

b. mold

c. original-tissue

Option (C)

Explanation:

In the frozen areas the temperature remains relatively cold which favors the preservation of the original hard and the solid parts of the organisms. The body becomes frozen due to the low temperature, as a result of which the tissues are not completely replaced by any type of secondary minerals.

In the given condition, the skull of Homo sapiens that are found to be preserved under the frozen rock bodies, are found to contain the majority of the original body parts, for which it can be considered as the original-tissue fossils.

Hence, the correct answer is option (C).

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.
