a crystal whose molecules are held together by weak physical bonding as opposed to chemical bonding. They usually are soft and have low melting points. They are also poor conductors of electricity basically due to the lack of electrons and ions in these solids. Examples of molecular crystals are- ice, solid carbon dioxide( dry ice) and rock candy. Iodine, phosphurus, sulphur, nitrogen, argon and water all form molecular crystals.
What else can I help you with?
Are Organic molecules are made from a small collection of simple precursors?
Yes, organic molecules are generally made from a small collection of simple precursors called monomers. These monomers can join together through chemical bonds to form larger molecules known as polymers, which make up the diverse array of organic compounds found in living organisms.
What happens to small molecules of protein in the mouth?
In the mouth, small molecules of protein are broken down by enzymes called proteases. These enzymes break down the protein molecules into smaller peptides and amino acids, which can then be absorbed through the lining of the small intestine for use by the body.
What kind of antigens are small simple molecules?
Small simple molecules that can act as antigens are referred to as haptens. Haptens are typically not immunogenic by themselves but can elicit an immune response when they bind to larger carrier proteins or molecules, forming a complex that the immune system can recognize. Examples include drugs like penicillin, which can trigger allergic reactions when they bind to proteins in the body.
What is The process by which small molecules pass through a membrane by moving from an area of high concentration to an area of low concentration is?
This process is called passive diffusion or simple diffusion. It does not require energy input and relies on the concentration gradient to drive the movement of molecules across the membrane.
Matter is made up of small particles called atoms or molecules?
true

Are most protein molecules small and simple to understand?
no
Simple molecules are further broken down in cells in a process called?
Simple molecules are further broken down in cells in a process called catabolism.
What is it called when small molecules build up larger molecules?
This process is called synthesis.
How do small polar molecules pass through the plasma membrane?
Small polar molecules can pass through the plasma membrane through a process called simple diffusion, where they move from an area of high concentration to low concentration without the need for energy or a transport protein.
The first person who proposed that small organic molecules could have arisen by chemical evolution of simple inorganic molecules was?
Aleksander Oparin
Nutrient molecules pass from the small intestine into the bloodstream through tiny structures called what?
Nutrient molecules pass from the small intestine into the through tiny structures called villi.
What is the process called when simple molecules are further broken down into cells?
Fermination
Does propane consist of small or large molecules?
Propane consists of small molecules. It is a simple hydrocarbon compound that is composed of three carbon atoms and eight hydrogen atoms.
What is large molecules to small molecules called?
The process of breaking down large molecules into smaller molecules is called catabolism. This process releases energy that cells can use for various functions.
Small circular molecules of extra DNA in bacteria are called what?
plasmids
What are the small molecules that make up proteins called?
Amino acids.
