We can measure how big things are, how warm they are, how heavy they are, and lots of other features as well. Units of Measurement provide standards for our comparisons, so that the numbers from our measurements refer to the same thing. For example, the metre is a standard unit to measure length.he property of the thing being measured is given as a number of units of measure. The number only has sense when the unit of measurement is also given. For example, The Eiffel Tower in Paris, France is 300 meters tall. That is, the distance from the top to the bottom of the Eiffel Tower is 300 meters.
The seven diatomic elements are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine and iodine. According to Princeton, diatomic molecules are molecules composed of only two atoms of either the same or different chemical elements.
Diatoms are a protist (single cell organism) which is part of the family of eucaryotic (Cells that have nuclei) algae. There are two types of diatoms, pennales (pennate shaped), and centrales (circular shaped).Diatoms like all plant cells are photosynthetic, meaning they make their own sucrose (sugar) from light, water, and nutrients. Diatoms use oils to store sugar. The oil also keeps the diatoms afloat.here are two types of diatoms, pennales (pennate shaped), and centrales (circular shaped).
