The diagram below shows the chemical structure of a type of lipid molecule called a phospholipid.
SVEN [57.7K]

Answer No 1:

Phospholipids are made up of phosphorus head and two fatty acid molecules.  These phosphorus head and fatty acid tail is joined together by glycerol. Fatty acid molecules are made up of Carbon, hydrogen and oxyge. Hence,carbon and hydrogen can be said as two other elements present in phospholipids.

Answer No 2:

The building blocks of lipids are glycerol and fatty acids.

Lipids can be described as vital organic molecules which are not soluble in water. They are made up of chains of carbon, hydrogen and oxygen. Someof the examples of lipids are fats and oils. Lipids are the main molecules present in an organisms cell membrane and hence have huge biological importance.

Answer No 3:

Lipids are biologically important molecules as they play very vital roles in the functioning of an organisms body. Two of the functions of lipids are:

  • Lipids and phosphorus molecules combine to form phospholipids. The phospholipids are the main molecules out of which the cell membrane is made. Hence, lipids play an essential role in providing the cell membrane its structure.
  • Lipids store energy and provide insulation to the body of an organism.

What structure keeps harmful chemicals out of animal cells?
Charra [1.4K]

Cell membrane protects animals cells from harmful chemicals.

Explanation:

The cell membrane is a tough covering composed of the phospholipids and proteins and forms a bilayer around the cells. This acts as a semi-permeable membrane and controls the transport of ions, organic molecules and solutes to and from the cell through selective permeability.

The hydrophilic and hydrophobic properties and the corresponding polarity of the cell membrane and ionization status of the chemicals prevent the entry of harmful substances into the cell. The cell membrane functions as a barrier system and prevents the flow.

What is the importance of bees to producers
Ierofanga [76]
Assuming you are referring to plants when you say producers, bees help spread "pollen", or plant offspring from plant to plant, which helps to fertilize those plants and help new ones grow.
