What type of organic compound is not soluble in water and is main component of the cell membranes?
The type of organic compound that is not soluble in water and serves as a main component of cell membranes is lipids, specifically phospholipids. These molecules have hydrophobic (water-repelling) tails and hydrophilic (water-attracting) heads, allowing them to form bilayers that create the structural foundation of cell membranes. This unique property helps maintain the integrity of cells and regulates the movement of substances in and out of the cell.
Which characteristic property of matter is illustrated by phenomenon of diffusion when some sugar is dissolved in volume of water?
This is the movement of molecules.
What is one important property that sets lipids apart from other molecules?
One important property that sets lipids apart from other molecules is their hydrophobic nature, meaning they are largely insoluble in water. This characteristic arises from their long hydrocarbon chains or rings, which do not interact favorably with water molecules. As a result, lipids play crucial roles in forming cell membranes and storing energy, distinguishing them from polar molecules like carbohydrates and proteins.
Is brittleness chemical or physical propertie?
Being brittle is a physical property.
What term describes the tendency of water molecules to cling to the wall of a blood vessel?
The term that describes the tendency of water molecules to cling to the wall of a blood vessel is "adhesion." This property allows water molecules to interact with the surface of the vessel, contributing to the overall behavior of fluids in the circulatory system. Adhesion, along with cohesion (the attraction between water molecules themselves), plays a crucial role in maintaining blood flow and pressure.
Which phrase best describes the property of selective permeability large molecules pass all ions pass all molecules pass some molecules pass?
The phrase "some molecules pass" best describes the property of selective permeability.
What property describes water sticking to other surfaces?
Adhesion is the property that describes water sticking to other surfaces. This occurs due to the attractive forces between the water molecules and the molecules of the surface it is in contact with.
Which of the following terms describes water molecules sticking to other water molecules?
The term that describes water molecules sticking to other water molecules is cohesion. This cohesive property is a result of hydrogen bonding between the water molecules.

When you devide the mass of a substance by its volume you get its?
density. Density is a physical property of a substance that describes how compact its molecules are within a given volume.
What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
What property is state of matter of an object?
The property that describes the state of matter of an object is called its physical state, which can be solid, liquid, or gas. This property is determined by the arrangement and movement of the particles that make up the object.
What statement describes a chemical property of water?
One statement that describes a chemical property of water is that water is a polar molecule due to its unequal distribution of electrons, which gives it the ability to form hydrogen bonds with other molecules.
What is a property that describes how something feels with 7 letters?
Texture is a property that describes how something feels.
Is brittleness chemical or physical propertie?
Being brittle is a physical property.
Do gases show the property of diffusion?
Yes, gases show the property of diffusion. Diffusion is the movement of gas molecules from an area of high concentration to an area of low concentration, and this process occurs naturally in gases due to their high kinetic energy and constant motion.
