There are no species of organisms alive today that are directly related to the triceratops. this information indicates that

a.
all organisms that lived in the past can be linked to newly evolved organisms in the present.
b.
triceratops are extinct, and no organisms alive today evolved from the triceratops.
c.
triceratops have evolved into a species that is so different, scientists are unable to discover the connection.
d.
fossil evidence is inconsistent with the theory of evolution.

There are no species of organisms alive today that are directly related to the triceratops. This information indicates that triceratops are extinct, and no organisms alive today evolved from the triceratops.

Explanation:

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
