In 1895, Ernest Overton proposed that cell membranes were made of lipids
According to the lipid bilayer theory, which Gorter and Grendel put forth in 1925, the cell membrane bilayer structure can be described using crystallographic research and observations of soap bubbles.
<h3>What is Cell membrane ?</h3>
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
- A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
- Biological membranes serve three main purposes. First, they prevent harmful substances from entering the cell. Second, they have receptors and channels that let certain molecules, like ions, nutrients, wastes, and metabolic products,
- Third, they divide metabolic processes that are necessary but incompatible that take place within organelles.

Natural selection. The trait that is unfavorable to the baby giraffe's survival will cause the death of giraffes with that specific gene that is responsible for a short neck vs a long neck. Natural selection causes traits that help the survival of the species will be carried throughout generations while unfavorable traits will be lost.
Explanation:
a wavelength is calculated by determining the distance between corresponding points on consecutive waves. Normally this is done by measuring from peak to peak or from trough to trough. When it comes to light, you can only see wavelengths of 400 to 700 billionths of a meter.
