Answer;
Phospholipid.

Phospholipid forms a double layer as the primary structure of cell membranes.

Explanation;
Cell membranes contains of lipids (phospholipids and cholesterol), proteins and carbohydrates groups that are attached to some of the lipids and proteins.
Phospholipids are composed of a polar head and non-polar (hydrophobic) tail. They line up such that the heads and the tail groups are side by side to form a single layer due to the interactions between the head groups and the tail groups. Two of these layers line up with the hydrophobic tail groups facing each other to prevent the hydrophobic groups away from the polar head groups of other phospholipids and from the water in the surrounding environment.

Scientists should not have the ability to patent their own research methods as this prevents additionally scientific knowledge to be present within the experimental sciences. The last step of the scientific method is to communicate and share your own findings, and without the ability to do so, it prevents constructive criticisms of the method as well as improvements that would otherwise be prevented from patenting. In the field of genetic engineering specifically, the Human Genome project or (HGP) was an international scientific investigation that promoted communication between scientists rather than the restriction of scientific knowledge. The results of this international collaboration led to multitudes of information being presented regarding human genetic makeup. Therefore, patents ultimately prevent the progression of the sciences and scientific knowledge.
