What is adhesion in the context of water?

Back

Adhesion is the property of water that describes its attraction to other substances, allowing it to stick to surfaces.

Front

What is a nucleotide?

Back

A nucleotide is the monomer of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are monosaccharides?

Back

Monosaccharides are simple sugars that have either 5 or 6 carbon atoms, such as glucose and fructose.

Front

What are the four types of carbon-based molecules in organisms?

Back

The four types of carbon-based molecules in organisms are nucleic acids, proteins, lipids, and carbohydrates.

Front

What is the function of lipids?

Back

Lipids serve as long-term energy storage, make up cell membranes, and act as signaling molecules.

Front

What are proteins made of?

Back

Proteins are made of amino acids, which are linked together by peptide bonds.

Front

What is the role of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats have no double bonds between carbon atoms, while unsaturated fats have one or more double bonds.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat allows it to absorb and retain heat, helping to regulate temperature in organisms and environments.
