Fossils almost never contain DNA. So how can we know how closely or distantly related fossil organsims are to living organisms

While it's true that Fossils hardly even contain DNA, they can still provide numerous clues in order to identify and verify an organism.

For example, in terms of Dinosaurs, their bones and fossils have provided enough evidence to provide an evolutionary link with modern birds.

Carbon dating is another way to find the age of a fossil which provides more information on it's surrounding habitat and the animals it interacted with.

The majority of the plasma membrane can be described as a bilayer of with associated proteins.

tester [92]

According to the research, the correct option is phospholipids. The majority of the plasma membrane can be described as a bilayer of <u>phospholipids</u> with associated proteins.

<h3>What is the plasma membrane?</h3>

It is a double layer of phospholipids and proteins, which perform functions of connection, transport and catalysis, which covers and delimits the cells, serving as a border between the inside and the outside of it.

In this sense, one of the peculiarities of phospholipids is that they are amphipathic, their molecules have a part that is soluble in water (that is, hydrophilic) and another that is not (hydrophobic), these lipids are primarily cholesterol, phosphoglycerides and sphingolipids

Therefore, we can conclude that according to the research, the correct option is phospholipids. The majority of the plasma membrane can be described as a bilayer of <u>phospholipids</u> with associated proteins.
