You probably got a false negative. M. luteus should be oxidase +. To determine M. luteus do a MSA plate which should not produce acid and barley grow. That means the plate wil â¦ l look red with a streak of yellow colonies due to the fact that M. luteus produces a yellow pigment.
A person adjusts the volume on their car radio. noun. Volume is the level at which something is heard or the amount of space that something takes up. An example of volume is how loud the radio is.
Volume is the amount of space an object occupies while density is the mass of an object per unit volume. You need to know the volume of an object before you can calculate its density. Calculating volume for regular objects can be done with a simple formula determined by the shape of the object.Common units for volume are cubic centimeters (cm 3), cubic meters (m 3), cubic inches (in 3), and cubic feet (ft 3).ow that you have determined the shape, which formula to use, and made the necessary measurements, you can calculate volume. By plugging in the values of your measurements and doing the math. Your finished product is the volume of your object. 1  Remember to express your answer in cubic units.
