Hey there!
1.The metric system is a decimal system of measurement whose units are based on certain physical standards and are scaled on multiples of 10.Metric units of length are easy to use because they are based on multiples of 10.
2.You can immerse the solid in water and measure the volume of the water displaced. The solid cannot dissolve in water.
3.A degree on the Fahrenheit scale must be smaller because there are 180 degrees between freezing and boiling as compared to 100 degrees for the same range on the Celsius scale.
Hope this helped @ShaggySnaps
The specific action of an enzyme with a single substrate can be explained using a Lock and Key analogy first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme).
Smaller keys, larger keys, or incorrectly positioned teeth on keys (incorrectly shaped or sized substrate molecules) do not fit into the lock (enzyme). Only the correctly shaped key opens a particular lock. This is illustrated in graphic on the left.
