At age 10 you carved your name into the trunk of a 20 ft oak tree at about chest-height (for your 10-yr-old self). Thirty years later you are back in your hometown and visit the park where this tree was growing. Your tree is still there! Which of the following should be true? O The tree ceased to grow at the point where you carved. The tree is taller O The trunk where you carved your name is wider. O The place where you carved is no longer at chest height- it is up higher on the trunk than it was before. O Looking at the tree, you can see how tall you were when you were ten years old.

the tree is taller and place you carved your name is wider

Explanation: trees increases at their branch tip and so the carving on the base of the tree will still remain at the same spot you Left it. As the tree grows consistently, the base also expand the trunk because the trunk of the tree grows outwardly therefore the carving will expand since the truck of the tree increases in diameter.

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.
