<h3>Answer:</h3>
The Fluid Mosaic Model declares that membranes are formed of a Phospholipid Bilayer with several protein molecules drifting about inside it. The ‘Fluid’ section describes how any components of the membrane can run nearby loosely if they are not connected to different components of the cell. The ‘mosaic’ section explains the ‘patchwork’ of proteins that are detected in the Phospholipid Bilayer.
<h3>Explanation:</h3>
There is a lipid bilayer in which the protein molecules are embedded. The lipid bilayer gives fluidity and elasticity to the membrane. Carbohydrates are also found in a cell membrane. The plasma membrane is said to be two-dimensional structure or liquid we can say which does not allow the lateral diffusion of membrane components. The plasma membrane has the texture of vegetable oil at body temperature, because of which the proteins and other substances move across it. That's why the plasma membrane is described as using the fluid-mosaic model.
Answer:
1678
Explanation:
In 1678, Antoni van Leeuwenhoek reported that he had observed "little animals" — protozoa — through a microscope. The discovery of the cell was made possible by the invention of the microscope, which was made possible by improved lens-grinding techniques.
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
