Answer:
Option D
Explanation:
In 1972, the fluid mosaic model was proposed by S. J. Singer and G. L. Nicolson to describe the structure of the plasma membrane found I living cells. The model describes the plasma membrane to possess components including phospholipid, proteins and cholesterol.
The phospholipid is arranged in two layers comprising of glycerol, two fatty acids and a phosphate group. The fatty acids which forms the tail are hydrophobic (water-fearing) while the phosphate group is water-loving (hydrophobic) giving the plasma membrane an AMPHIPATHIC nature. The other component as proposed by the model are membrane proteins and cholesterol, all responsible for the fluidity of the membrane.
Answer:
By bonding with each other.
Explanation:
Larger macromolecules are formed from smaller macromolecules by making bonds with each other. carbohydrate is a macromolecule which is formed from glucose which is a micromolecule. Proteins is also a macromolecule composed from amino acids while lipid is also a macromolecule that are formed from fatty acids. These small micromolecules join together forming covalent bonds with each other.
The mass is increased as two things are added together so the two masses of the two substances are added together.
No, because its genes are still the same. To evolvewould mean that the frog had one set of genes as a tadpole, then a different set as an adult. It just doesn't work that way. The genes are the same.
