A substance in which the exact combination of elements is always the same, is called a compound.
elements
A substance in which all atoms are identical is called an element.
Compounds always contain elements in exact ratios, based on the chemical formula of the compound. This means that the elements are present in specific and consistent proportions in the compound.
The exact time it was created.
A compound is a substance composed of two or more elements chemically bonded together in exact ratios. For example, in water (H2O), the elements hydrogen and oxygen are combined in a 2:1 ratio. Another example is carbon dioxide (CO2), where carbon and oxygen are combined in a 1:2 ratio.
Offspring inherit a combination of genes from both parents, but this doesn't necessarily mean they maintain the exact gene combinations of either parent. Genetic recombination and independent assortment during meiosis result in unique combinations of genes in offspring. These genetic variations contribute to the diversity within a species.
The exact mix is different depending on the star's age and size, but hydrogen and helium are always the two most prevalent elements.

Heat is energy, not a substance. When reactive elements combine they form more stable compounds. The exact substance formed depends on the elements. e.g. hydrogen and oxygen form water while sodium and chlorine form common table salt.
It is a substance. A pure one to be exact, classified as one of the elements on the periodic element table.
No, they do not.
DIFFERENCES• Compounds have two or more different types of atoms.• Elements are pure substances that have the exact same type of atom.SIMILARITIES• They are both pure substances.
