When a metal and non-metal react to each other, their atoms have a tendency to transfer ___.

Electrons

Explanation: Atoms are made up of electrons, protons and neutrons. Protons and neutrons are located in the nucleus while electrons are located outside the nucleus where they revolve round the nucleus in their orbitals. Electrons are involved in chemical reactions.

During chemical bonding, a metal atom transfers its valence electrons to a non-metal atom. In this type of bond, the metal atom losses electron while the non-metal atom gains electron. The metal atom losses electron to form a positively charged ion and attains a stable octet structure while the non-metal atom gains electron to form negatively charged ion and attains a stable duplet or octet structure. This type of bond is called ionic bond or electrovalent bond.

answer; ///i believe that the correct answer is (the worksheet);

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.
