Explanation:
The polar nature of the membrane’s surface can attract polar molecules, where they can later be transported through various mechanisms. Also, the non-polar region of the membrane allows for the movement of small non-polar molecules across the membrane’s interior, while preventing the movement of polar molecules, thus maintaining the cell’s composition of solutes and other substances by limiting their movement.
Further explanation:
Lipids are composed of fatty acids which form the hydrophobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons. Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties i.e. they are amphiphilic. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.
Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane.

A polar bond that occur(s) when atoms share electrons unequally.
A Nonpolar Covalent Bond occur(s) when atoms share electrons equally.
<h3>What is a Nonpolar Covalent Bond?</h3>
This is known to be a bond that is said to have created if atoms are said to share their electrons in an equal way.
Note that this is one that often occurs if two atoms are said to be the same or are similar or have the similar electron affinity.
Note also that the closer the values of a given electron affinity, the stronger the attraction.
Therefore, A polar bond that occur(s) when atoms share electrons unequally.
A Nonpolar Covalent Bond occur(s) when atoms share electrons equ

Answer: Option A. Delusion
Explanation:
A delusion is a belief that is clearly false and that indicates an abnormality in the affected person’s content of thought. The key feature of a delusion is the degree to which the person is convinced that the belief is true.
A person with a delusion will hold firmly to the belief regardless of evidence to the contrary. The false belief is not accounted for by the person’s cultural or religious background or his or her level of intelligence.
Where are the statements, huh wait what
Answer:
When a covalently bonded molecule has more electrons in one area than another, it is called a polar molecule. The electron cloud model can show an unequal sharing of electrons. ... This shows that electrons are more attracted to the oxygen end of the molecule than the hydrogen end, making the water molecule polar.
