Is lactose a base?
No, lactose is a disaccharide sugar, not a base. It is composed of one molecule of glucose and one molecule of galactose linked together.
Explain why O2 is a molecule but not a compound?
Oxygen gas (O2) is a molecule because it consists of two oxygen atoms chemically bonded together. However, it is not a compound because it is composed of only one type of element, oxygen. Compounds are substances made up of different types of atoms chemically bonded together.
What is a carrier that transports only one type of solute at a time is called?
A carrier that transports only one type of solute at a time is called a uniporter. Uniporters are integral membrane proteins that facilitate the transport of a single type of molecule across cell membranes.
How many DNA molecule in a chromatid?
Each chromosome is originally made of one DNA molecule.
At the end of replication each new DNA molecule is composed of?
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
What is composed of only one type of molecule?
What is composed of only one type of molecule
Is a compound a molecule composed of one type of element only?
No, a compound is a substance composed of two or more different elements chemically bonded together in a fixed ratio, such as water (H2O) or carbon dioxide (CO2). An element consists of only one type of atom, such as oxygen (O) or hydrogen (H).
A molecule that is composed of only one kind of atom is?
An elemental molecule, like H2 or O2.
What do molecules have to do with compounds?
Compounds can actually be molecules. A molecule is simply the smallest amount of something. A compound is a molecule composed of more than one type of atom. For instance, carbon dioxide has a chemical formula of CO2. Therefore there is one atom of Carbon, and two of Oxygen. Together, they form a single molecule of carbon dioxide. On the other hand, the element oxygen is composed of two oxygen atoms, which make up one molecule. However, this molecule is only composed of ONE atom, and is thus not a compound but an element.
What new substance if one molecule of carbon combine with two molecule of oxygen?
It is sort of tricky question. One molecule of carbon can combine with only one molecule of oxygen. It can not combine with two molecules of oxygen. Incidentally one molecule of carbon is composed of one atom of carbon. One molecule of oxygen is composed of two atoms of oxygen.
What is made up of only one type of element?
An example of a molecule that contains only one type of atom is a diatomic gas. Diatomic gases include Hydrogen, Oxygen and Nitrogen. Inert gases are not diatomic. A molecule of any element is made up of one type of atom. So carbon, hydrogen, oxygen and ozone molecules, among many others, are each made up of one type of atom. However the oxygen molecule is made of atoms that are different from those in the hydrogen molecule.
Is butane a pure substance or a heterogeneous homogeneous mixture?
Butane is a pure substance. It is a compound composed of only one type of molecule (C4H10) and is chemically uniform throughout.
What is term for matter that is made of only one type of element or molecule?
The term for matter made of only one type of element is "pure substance," while matter made of only one type of molecule is called a "pure compound."
What are the 3 types of ATP in a molecule?
There is only one type of ATP and it is a molecule all of its own.
What is asubstance that is composed of only one type of atom i?
An element
Is sucrose a monosacchride?
No. sucrose is disaccharide. One sucrose molecule is composed of one glucose molecule and one fructose molecule.
Is nitrogen gas heterogeneous?
No. It is an element, which is homogeneous matter.
