What reproductive process do bacteria use by forming two identical cells from one parent cell?
nikdorinn [45]
This is a kind of an asexual reproduction called binary fission. This involves division of the parent cell into two identical cells. This is common for prokaryotic reproduction like archaea and bacteria and it also happens in some single-celled eukaryotes such as protists and unicellular fungi.

What type of bond is most likely to form between two nitrogen (N) atoms:
IRISSAK [1]

Answer:

B. Nonpolar covalent bond

Explanation:

Between two Nitrogen atoms, a non-polar covalent bond would be formed.

So, what is the nature of a covalent bond, and what makes a covalent bond non-polar?

A covalent bond is a type of bond that forms between two atoms that shares their valence electrons. The valence electrons are donated by the two atoms and they are shared in order to achieve an octet. This bond type is predominantly between atoms that have an electronegativity difference less than 0.5. Using the electronegativity values, we see that a difference of 0 would be obtained.

Due to equal affinities of the two atoms for the valence electrons, none of them will pull the electrons closer to themselves. There won't be any form of charge separation on the two atoms and a Nitrogen molecule will form. This makes the bond type a non-polar covalent type.
