Why do marine organisms living in polar regions have a very high proportion of cholesterol in their membrane?
Marine organisms living in polar regions have a very high proportion of cholesterol in membranes to keep the membranes more fluid and keep the molecules moving faster because in cold temperature, molecules move slower.

Why do marine organism living in polar regions have a very high proportion of cholesterol in their membranes?
Organisms living in extremely cold temperatures run the risk of hypothermia and even their cells freezing. Cellular membranes with more cholesterol help insulate the organism and are less prone to freezing.
What are the regions of the chloroplast outside the thylakoid membranes?
stroma
What is small organisms that live in the sunlight regions of the oceans?
Small organisms that live in the sunlight regions of the ocean is called Plankton!
Which statement most accurately explains why cholesterol and phospholipids are amphipathic but fats are not?
Cholesterol and phospholipids contain both hydrophilic and hydrophobic regions; fats are primarily hydrophobic. Save
What question did Charles Darwin answer?
Why do different regions have different organisms
What Are nonpolar macromolecules found in cell membranes they prevent ions from freely entering cells.?
Nonpolar macromolecules found in cell membranes primarily include lipids, such as phospholipids and cholesterol. These molecules form the lipid bilayer, which acts as a barrier to ions and polar molecules, preventing them from freely entering or exiting the cell. The hydrophobic (water-repelling) nature of these nonpolar regions restricts the passage of charged particles, thereby helping to maintain the cell's internal environment. This selective permeability is crucial for cellular function and homeostasis.
Which layer supports living organisms?
The layer that supports living organisms is the biosphere, which encompasses all regions on Earth where living organisms can exist. It includes the atmosphere, hydrosphere, and lithosphere where life is found.

What molecules in membranes allow lipids and water to mix?
Phospholipids are the main molecules in membranes that allow lipids and water to mix. They contain both hydrophobic (lipid-loving) and hydrophilic (water-loving) regions in their structure, enabling them to form the basic structure of cell membranes. The hydrophilic head interacts with water, while the hydrophobic tail interacts with lipid molecules.
