20, one for each type of different amino acid.
Yes, nitrogen is necessary for life to exist because it is a crucial component of proteins, DNA, and other essential molecules in living organisms.
Carbon is the backbone element of organic molecules, providing stability and structure due to its ability to form covalent bonds with other carbon atoms and different elements. It can form diverse functional groups, allowing for a wide variety of molecules with different shapes and properties to exist in nature. Carbon's flexibility in bonding contributes to the complexity and diversity of organic molecules found in living organisms.
No, molecules and elements are not the same thing. An element is a pure substance made of only one type of atom, while a molecule is a group of atoms bonded together. Elements can exist as single atoms or as molecules depending on their chemical composition.
there are alot of different species but there is about the same number of angiospems so there is about 200,000-300,000
RNA does not typically form a double helix structure like DNA. Instead, RNA molecules usually exist as single strands that can fold into complex shapes due to their sequence and interactions with other molecules.
0 equator is the minimum degrees of latitudes
You can control the number of water molecules that exist in a hydration compound by regulating the number of hydrogen and hydroxyl ions.
molecules
They are made of different kinds of molecules.
An isomer is a molecule or compound that has the same number of atoms as another but a different structure, different physical and chemical properties. Isomers can exist because in large molecules there are several different ways you can position the same elements to make different structures.
The were not invented, they exist. Atoms and molecules were discovered.
Ozone exists as triatomic molecules. O3
Isotopes have the same number of protons an electrons; the number of neutrons is different.
Isotopes have the same number of protons and electrons; the number of neutrons is different.
Hydrogen molecules do exist but they are less stable than hydrogen atoms. This is because hydrogen molecules require a large amount of energy to form since hydrogen atoms are highly reactive and tend to exist independently. Additionally, hydrogen molecules can easily dissociate into individual atoms at lower temperatures.
They have completely filled valence electrons, hence are stable, chemically inert. So they exist as mono atomic species and not as molecules
Yes, it is true. Isotopes have the same number of protons an electrons; the number of neutrons is different.
