According to the fossil record, which statement
is accurate?
(1) most of the species that have lived on earth
no longer exist.
(2) most of the species that have lived on earth
still exist today.
(3) fossils of species that never existed can be
found.
(4) fossils of species that never existed, but will
exist in the future, can be found.

(1) Most of the species that have lived on Earth no longer exist.

Explanation:

Fossil describes the remnant or trace of animals or plants in a geologic age that is preserved in the Earth's crust. It can be studied to give a fossil record, which is an evidence of past existence of a plant or an animal.

Fossil record is the history of life of an organisms documented by fossil that has been preserved in rocks. It helps paleontologists, archaeologists, and geologists to make accurate predictions about events and species.

Scientists believe that almost 99.9% of species of different organisms that have lived on Earth are now extinct. Therefore according to fossil record, most of the species that have lived on Earth no longer exist.

yes you are doing it right great gob

explanation:

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
