Why is the streak plate preferred over the spot inoculations in the blood agar test?
The kidneys filter about 150 to 180 liters per day, so that would be about 6 to 7.5 liters an hour. 6 liters = 1.6 US (1.3 UK) gallons 7.5 liters = 2 US (1.6 UK) gallons
Why is the streak-stab technique preferred rather than incubating the plates anaerobically?
The streak-stab technique is preferred over incubating the plates anaerobically because when isolating colonies allows biochemical testing to be performed. When the plate is incubated anaerobically it lacks oxygen and can not be biochemically tested.
How do you test out a streak?
by strecting it on a streak plate
How do you determine the streak of a mineral whose Mohs scale is higher than the streak plate?
You can determine the streak of a mineral whose Mohs scale is higher than the streak plate by either filing or crushing with a hammer before rubbing the sample on a streak plate.

What happens if you rub the mineral across a streak plate but the mineral does not leave a streak?
The lack of a streak would indicate that the mineral is harder than the streak plate, or the color of the streak is the same as the color of the streak plate.

Why do some very hard minerals leave no streak?
Some minerals are harder than a streak plate and will therefore leave no streak or the powder of the ceramic streak plate.
How do you determine the streak of a mineral whose Mohs scale is higher than the streak plate?

Why doesn't the mineral topaz leave a streak on a streak plate?
It leaves a scratch instead of a streak because Topaz has a higher number on the Moh's scale compared to the streak plate.
