The blood<span>, which is now low in oxygen, is now collected in veins and travels to the right atrium and into the right ventricle. Now pulmonary circulation starts: The right ventricle pumps </span>blood<span> that carries little oxygen into the pulmonary artery, which branches off into smaller and smaller arteries and capillaries.

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.

This question is supposed to have a table showing species member tested and the type of cells tested and the results. Based on this table, the species member that would be unlikely to pass the gene mutation on to its offspring is species member 4: [Body cells (+) and Sperm (-)] Hope this helps.
