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.

Answer:
(4) As time increased, distance remained
the same
Explanation:
The graph shows that the student measures equal distance everyday from the bridge to the rock for 7 days.
Everyday has an equal distance measured by the student all through the week.
Let's say the point on the vertical axis which represents distance measured is about 1.5 meters. It means that, for day 1, he measures 1.5 meters, day 2, he measured 1.5 meters, by day 3 another 1.5 meters. Same he does for 7 days. For the first 3 days, he would have measured 1.5 m × 3 = 4.5 meters.
This means that, as time (days) increased, distance measured each day remains the same.
