PLEASE HELP ME, will mark brainliest,

why do three species have similarities and differences in their body structures, and how can Omar use the structure to determine if the new fossil is more closely related to horses or sloths?

Explanation:

The Theory of evolution suggests that the organism has evolved from a common ancestor that is "Descent with modification".

In the given question, the new fossil was found and the anatomical structures were compared with that of Horses and the Sloth.

The similarities in these three species show that they were evolved from the common ancestor but the differences in the number of teeth and bones in toes with the sloth show that the fossil and the sloth are not closely related.

The new fossil is more closely related to the horses because the three anatomical traits are more similar to the anatomical traits of the horses. This could show that the species are more closely related.

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.
