Lipids all have one thing in common - they do not mix well with water. You can see this quite well if you try to combine oil and water. No matter how much or how hard you shake them together, they remain separated. This can be useful for organisms. For example, ducks produce lipids in their feathers, allowing the water to roll right off their backs and helping the ducks stay afloat.

Phospholipids are made up of two fatty acids (long chains of hydrogen and carbon molecules), which are attached to a glycerol 'head.' The glycerol molecule is also attached to a phosphate group, and this is the hydrophilic part of the molecule. The 'tail' ends of the fatty acid chains opposite the glycerol is the hydrophobic part of the molecule

The most important function for a phospholipid is to form the phospholipid bilayer. In this bilayer, the phospholipids are arranged so that all the hydrophillic heads are pointing outward and the hydrophobic tails are pointing inward. This arrangement comes about because the areas both outside and inside your cell are mostly water, so the hydrophobic tails are forced in.

THis is the required answer.

In an ionic compound, the attraction between actions and _________ hold the compound together

Nady [450]

Answer:
The correct option in blank is anion.

Explanation:
Ionic compound is formed by the transfer of electron from one atom to another atom. When an electropositve atom lose an electron it form cation, whereas as anion is formed when an atom gain an electron. These actions and anions then attract each other and form an ionic compound.
I hope it will help you.

Example:
The formation of NaCl is best example of ionic compound. Na has one electron in its outer most shell which can easily be removed to form Na+, while Cl has seven electron in its outer most shell so it can easily gain an electron lost by Na to form Cl-. Then these ions attract each other and form NaCl as shown in the figure.
