What else can I help you with?
Which scientist determined that the fundamental unit of DNA was a nucleotide containing one of four possible bases a sugar molecule and a phosphate group?
Levene
What is the major characteristic that distinguishes lipids from other macromolecules?
A lipid is a hydrophobic molecule, molecules in this group are fatty acids, waxes, and sterols. A carbohydrate is a hydrophillic molecule and moles cules in this group are sugars: monosaccharides and starches.
Why is water a pure substance?
Water is considered a pure substance because it is made up of only one type of molecule, which is H2O. It maintains consistent properties and composition throughout, with a fixed ratio of hydrogen to oxygen atoms in every molecule. This distinguishes it from a mixture, which contains multiple types of molecules.
What is the charge density of a molecule?
The charge density of a molecule refers to the distribution of charge within the molecule. It is usually calculated as the total charge of the molecule divided by the volume it occupies. This information is important for understanding the molecular structure and reactivity of the molecule.
What is the definition of molecule?
A molecule is a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can participate in a chemical reaction. It can be a combination of the same or different elements.
What is the telltale functional group that distinguishes an alcohol molecule?
hydroxyl
Is h2o living or nonliving?
H2O (water) is a nonliving substance. Living organisms, such as plants and animals, require water to survive, but water itself is not alive.
Is a molecule living or nonliving?
A molecule on its own is considered nonliving. Molecules are the building blocks of living organisms, but they do not exhibit life processes like growth, reproduction, or response to stimuli on their own.
What is the smallest fundamental unit of a covalent compound called?
The smallest fundamental unit of a covalent compound is called a molecule. It is formed when two or more atoms share electrons to become stable.
Do living things depend upon nonliving things?
The oxygen molecule, theoretically, does not live. We depend on it. So yes.
Special molecule that provides energy for a cells activities?
CH2O (glucose) is the most fundamental molecule metabolized by cells (in conjunction with Oxygen) for energy.
What is the smallest unit of a molecule?
An atom. It not REALLY indivisible, but it is the fundamental building block of molecules.
Is water an example of molecule?
Water molecule is an important and good example of polar covalent molecule
What molecule is important in the formation of the heme portion of the hemoglobin molecule?
iron
Which type of biological molecule is Peptide bond is found in?
Peptide bonding is the fundamental bonding in all types of Proteins.
What is removal heat?
On a fundamental level it is reducing the amount of energy in a molecule or atom. More prosaic it is to to reduce the temperature of something.
Molecule in a sentence?
A molecule of water contains one oxygen atom and two hydrogen atoms.
