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.
Answer:
I would say We don't have enough evidence or Cell theory is still changing.
Explanation:
There are so many cells in everything so it's almost impossible to know exactly what is going on. Theories about cells have been going on for over 500 years, and we still don't know exactly what is what.
When an athlete eats more protein or amino acids than he or she needs, the extra amino acids are either used in building the muscle tissues or are used in energy expenditure.
Proteins are the macromolecules composed of amino acid as polymers. Protein is an essential food component because it helps in the synthesis and repair of body parts, it help in growth and development, and also provides fuel to the body.
Muscle tissues are the ones responsible for the movement of the complete body. The tissues are rich in blood supply. They are of three categories: skeletal, cardiac and smooth. Any movement in body is possible only because of the contractions and relaxations of muscles.
