Which of the following statements is false? a.) extinction is the permanent loss of species b.) extinction is irreversible c.) extinction can be local or global d.) extinction is not normal but only happens because of human influences

D.) Extinction is not normal but only happens because of human influences.

Explanation:

Extinction is a state or phenomenon where a family or group of a particular species may all be extinct/ gone permanently. This event happens when the very last of any biological species is destroyed or removed or died, leaving no possibility of any future 'generation' to emerge.

Extinction is a permanent loss of the whole race/ species, with no offspring to continue the generation. It is also an irreversible process which means it cannot be reversed or taken back. It can and be local or global, can happen in all scales worldwide but it is not happening because of human interference.  It can occur due to man made events but also at the same time, it can also happen due to the ecological, geological and biological issues.

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.
