Covalent bonds are formed when two atoms are able to <em>share</em> electrons.

Iroinic bonds are form when two atoms are <em> </em> electrons from each other to complete the bond. This results in a pair of ions.


<u>Covalent bonds:</u>

  • Have a definite shape.
  • Have a low melting point.
  • At room temperature they are in a liquid or gas.
  • They occur between two non-metals.

<u>Ionic bonds:</u>

  • Have no definite shape.
  • Have a high melting point.
  • At room temperature they are solid.
  • They occur between a metal and a nonmetal.

Answer: e.Woman; there is not enough information to tell if the nondisjunction happened in meiosis I or II.

Explanation: There is not enough information to tell if the nondisjunction happened in meiosis I or II. Nondisjunction can occur during meiosis I and meiosis II, resulting in abnormal chromosomes number of gametes. The important difference between nondisjunction in meiosis 1 and Ii is that during meiosis 1, homologous chromosomes fail to separate while in meiosis II, sister chromatids fail to separate meaning it could have happened in meiosis I or II but we were not given.
