species
The organization of life goes as follows, from largest to smallest. Domain, Kingdom, Phylum, Class, Order, Genus, Species. There are such things as sub-species, but I don't believe such is used outside of differentiating members of a species.
Subspecies is the term.
Molecules, and atoms that make up molecules. An atom is made of smaller particles called protons, electrons, and neutrons. Smaller to this are groups such as fermions, Hadrons, Bosons
When a species is made up of different smaller groups, each of those groups is typically referred to as a population. Populations can exhibit unique characteristics and adaptations based on their specific environmental conditions and genetic makeup.
atoms make up molecules, which make up cells, which make up tissues, which make up organs, which make up body systems, which make up a body
Cells and fibers are the smaller parts that make up muscle tissue.
Atoms make up elements. groups of elements make up molecules. Groups of molecules form macromolecules (polymers) which make up cells.
The fly is in the class of animalia and in the sub-class insectia. An insect is just a more specific type of animal (a class), just like a mammal or a reptile. Living things are classified from large, broad groups into smaller and smaller groups. The largest of these that is important here is a kingdom. Kingdoms are broken up into phyla, which are smaller. Phyla are then broken up into classes, which are broken up into orders, which are broken up into families, etc. Fruit flies are classified into two families (Tephritidae and Drosophilidae) which are parts of the order Diptera (which includes all flies). Diptera is part of the class Insecta (which includes all insects). Insecta is part of the phylum Arthropoda (which include insects, arachnids, and crustaceans). And Arthropoda is part of the kingdom Animalia, or the animal kingdom. If you are looking for the "common fruit fly" its scientific name is Drosophila melanogaster.
Subspecies is the term.
Amino acids are the smaller building blocks that make up proteins.
There are about 50 ethnic groups in Canada.
