The correct answer is: A) The polarity of membrane phospholipids
Factors that affect membrane permeability are
1. Chemicals :
Some of the organic solvents such as chloroform and ethanol can dissolve the membrane and thus, destroy the selective permeability of the membrane.
2. Temperature :
Too high temperatures denature the protein that are in the structure of the membrane destroying its selective permeability. On the other hand, too low temperature slows down molecule movements and the permeability decreases.
3. Cholesterol:
Increases the permeability by reducing the barrier formed by phospholipids’ heads
4. The saturation of hydrocarbon tails in membrane phospholipids:
Saturated fatty acids decrease permeability of the membrane because they get very close together, which makes it harder for the molecules to pass through.
Answer:
Option A, hydrophilic/hydrophobic forces
Explanation:
The cytoplasmic membrane consists of phospholipids which have both the hydrophilic and hydrophobic regions and hence are amphipathic in nature. Due to this structural complexity, phospholipids produces barrier both at the interior and exterior of cell and hence form a membrane bilayer under suitable conditions. For instance when it is in water, it arrange itself in a way that their hydrophobic tails lie at the inner side and hydrophilic heads face outer side.
Hence, option A is correct
Answer:
the first,second, and third are the answer if this is multichoice which i am guessing it is.
Explanation:

The eight most common types of synthetic organic polymers, which are commonly found in households are:
Low-density polyethylene (LDPE)
High-density polyethylene (HDPE)
Polypropylene (PP)
Polyvinyl chloride (PVC)
Polystyrene (PS)
Nylon, nylon 6, nylon 6,6.
