The Hydrophobic phospholipid "tails." Cell Membranes are composed of lines of hydrophilic (water loving) phospholipid heads that face outside the cell and inside the cell. On the inside of the membrane, however, are hydrophobic (water hating) phospholipid tails, which repel charged particles.
The structure in a cell membrane that repels charged particles is the lipid bilayer. The lipid bilayer is composed of phospholipids, which have hydrophilic (water-loving) heads and hydrophobic (water-repelling) tails. This arrangement prevents charged particles from easily crossing the membrane.

What repels electric charge?
A negative charge will repel a negative charge.
How does the structure of phospholipids linear molecules with a polar end and a nonpolar end relate to their function in the cell membrane?
The linear structure of phospholipids allows them to form a bilayer in the cell membrane due to their amphipathic nature, with the polar head facing outward towards water and the nonpolar tails facing inward. This arrangement helps create a barrier that controls the movement of substances in and out of the cell, contributing to the selective permeability of the cell membrane.
What of the cell membrane repeals water?
The lipid bilayer of the cell membrane repels water due to its hydrophobic nature. The hydrophobic tails of the phospholipids face inward and prevent water molecules from passing through easily, creating a barrier. This property helps regulate the movement of molecules into and out of the cell.
How is paint given a positive charge when it leaves a spray nozzle?
Paint is given a positive charge when it leaves a spray nozzle through a process called electrostatic spray painting. In this process, the paint is positively charged by passing it through a high-voltage electrode in the nozzle, creating a positive charge that repels the positively charged paint particles, causing them to disperse evenly and adhere more effectively to the surface being painted. This leads to better coverage and less overspray.
What if there was only positive charged particle in the universe?
That's not a question that can be answered. We do not know why there are three generations of fundamental particles, and so it stands to reason that we do not know what would be necessary for only one generation. I hypothesize that the constants and forces of nature would be entirely different, but this is making an assumption that our three generations of particles rely on the constants and forces of nature and I cannot prove my assumption. The simplest answer, and by far the least satisfying, is I don't know. <><><><><> Its a matter of balance. With only a positively charged particle, everything would repel everything else and the universe would fly apart. With oppositely charged particles, some matter repels and some attracts. Of course, this does not consider the strong force, which is always attractive, nor does it consider the weak force, in which neutrons factor into the equation.
What pairs of charged particles will result in a repelling force acting between the particles?
+ repels + , - repels - .
A positively charged ion will bond with?
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
What is a force that attracts or repels particles?
magnetic pole
What are the main ideas of e Rutherford gold foil experiment?
basically, Rutherford shot postively charged particles at a thin sheet of gold foil. most of the particles passed straight through, but some bounced off at sharp angles. This implies that most of the atom is empy space (which is why most of the particles go straight throught) , but there is a positively charged nucleus at the center (which repels the postively charged particles, so if a particle hits the nucleus, it bounces off )
Does a positive electric field repels a positive charged object?
Yes.
Does current flow through wires?
It will flow if there is a voltage. Basically, that implies there is an electric field that attracts or repels charged particles.It will flow if there is a voltage.

What prevents charged molecules from diffusing across the cell membrane?
Charged molecules are prevented from diffusing across the cell membrane due to its hydrophobic interior, which repels charged molecules. Additionally, the presence of selective ion channels and transport proteins in the membrane allows for controlled movement of charged molecules in and out of the cell.
What is the force that repels particles with a similar charge or attracts particles of differing charges.?
The force that repels particles with a similar charge is electrostatic repulsion, which is the result of like charges repelling each other. The force that attracts particles of differing charges is electrostatic attraction, which is the result of opposite charges attracting each other.
What are some ways in which an object can become charged?
Some ways in which an object can become charged are friction, contact and induction.
Why does a balloon repel running water?
A balloon repels running water due to the static charge it acquires when rubbed against hair or clothing. The balloon becomes negatively charged, which repels the negatively charged water molecules. This creates a force that pushes the water away from the balloon.
What repels electric charge?
A negative charge will repel a negative charge.
What thing holds protons and electrons in the nucleus?
The strong nuclear force holds protons and neutrons together in the nucleus. This force is stronger than the electromagnetic force, which repels positively charged protons. Electrons are held in orbit around the nucleus by the electromagnetic force.
