In order to understand why the laws of inheritance work as they do, scientists had to look into the interior of cells. Cells are the building blocks of life, and all living things—from bacteria to human beings—are composed of them. The number of cells varies greatly from organism to organism: A bacterium has just one cell; an average-sized adult human has between 60 trillion and 100 trillion. Most cells are too small to be seen with the naked eye and must be viewed under a microscope. In the human body, almost all cells vary between <span>1 </span><span>⁄25,000 of an inch and </span><span>1 </span>⁄125,000 of an inch in diameter, although there is a nerve cell in the upper leg that, while extremely thin, is several feet long. Other cells are larger. A hen's egg, for example, is a single cell, and the largest cell of any organism on Earth is the ostrich egg, which weighs about a pound. Even the smallest cell contains a complete copy of the genetic information that gives an individual organism the traits that make it what it is and not some other thing. Cells have what are called life cycles. They are created, live, reproduce, and die. It is during the process of reproduction, or cell division, that genetic information is passed along from generation to generation.<span>

The hydrogens and oxygen of a water molecule are held together by ______ bonds. select all that apply.
zavuch27 [327]

The hydrogens and oxygen of a water molecule are held together by covalent bonds.

<h3>What are covalent bonds?</h3>

A covalent bond is an electron exchange that causes the production of electron pairs between atoms. Covalent bonding is a stable equilibrium of the attractive and repulsive forces between two atoms that occurs when they share electrons.

Bonding pairs or sharing pairs are other names for these electron pairs. Because electrons are shared among several molecules, each atom can reach the equivalent of a full valence shell, resulting in a stable electronic state.

In organic chemistry, covalent bonds are much more common than ionic bonds. Covalent bonds unite the atoms in a single water molecule, whereas hydrogen bonds join two water molecules. Water develops a covalent bond when oxygen shares an electron with each hydrogen atom.

With what elements does nitrogen form ionic bonds?
Andrew [12]

Answer:

Group 1 and 2 elements

Explanation:

Nitrogen, a non-metal will form ionic bonds with most group 1 and group 2 metals on the periodic table.

How does ionic bonds form?

  • They are bonds formed between a highly electronegative specie and one with very low electronegativity.
  • As such, ionic bonds forms between metals and non-metals
  • In this bond type, the metal due to its electropositive nature will transfer electrons to the non-metals for it to gain.
  • The non-metals becomes negatively charged as the metal is positively charged.
  • The electrostatic attraction between the two specie leads to the formation of ionic bonds.

Most metals in group 1 and 2 fits in this description. Some of them are calcium, magnesium, lithium, Barium e.t.c.

It mostly favors group 2 metals.
