The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. The amount of each depends upon the type of cell, but in the majority of cases phospholipids are the most abundant, often contributing for over 50% of all lipids in plasma membranes.
The answer is lower because having to return to a pre disturbance size will likely affect its genetic variation to be lower compared to the original population where in its genetic variation will be greater compared to those in pre disturbance size.
Answer:
Scientists use a system like this to group living things. the grouping are based on common traits. this system helps scientists to study the million of organisms of new organisms are discovred each year

Explanation:
Answer:
The correct answer will be- Transmission electron microscope
Explanation:
A Microscope is an optical instrument designed to view the microscopic things which could be living or non-living around us.
The internal structure of a microscope can be viewed by a light microscope mainly dark-field microscope but a detailed structure of a microscope can be viewed by an electron microscope mainly a transmission electron microscope.
The transmission electron microscope studies the internals structure of the cell by creating the 2D images by passing the beam of electrons through the specimen.
Thus, a transmission electron microscope is the correct answer.
