What is the most accurate statement about fernsa) ferns are nonvascular plants. b) ferns belong to the same phylum as moss. c) ferns developed after mosses appeared. d) scientists have found several hundreds species of ferns. direct answer .

The most accurate statement about ferns is that scientist have found several hundreds species of ferns.

Ferns are the vascular plants that has less ecological importance but they are used as food, medicine, biofertilizer. They belong to a group of vascular plants and they are approximately 10, 560 species of exact known species of ferns. Ferns were first observed in the fossil record about 360 million years ago.

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.
