The primary driving force that stabilizes lipid bilayers is the formation of hydrophobic bonds between fatty acid chains in phospholipids and protein.
The cell membrane is made up of phospolipid bilayer with proteins embedded in between
Lipid bilayer is the structure present in the biological membrane. It consist of two layers of lipids with hydrophilic end facing each other and hydrophobic end facing the outer side.
the inner layer has both the hydrophobic end of the lipid molecules facing each other and bonded by hydrophobic bond van der waals forces.
The outer molecules are bonded with the protein molecules through hydrophilic bonds called hydrogen bonds.

The position of the Earth in the solar system and more regional effects, such as carbon dioxide levels, all play a role in the causes of ice ages. Thus, option A is correct.
<h3>
What are factor that involve in ice age on earth?</h3>
When the orbital cycle turns back, these feedbacks—involving the spread of ice and the emission of greenhouse gases—work in reverse to warm the Earth once more.
A prolonged period of cooling of the Earth's surface and atmosphere is known as an ice age, which is marked by the development or presence of polar and continental ice sheets as well as alpine glaciers.
Flooding has increased along the U.S. coastline as a result of the warming, rising, and acidifying of the seas.
Therefore, The Earth is currently facing an ice age.
