What is the negative control in a fermentation lab?
Howdy there! Negative control for a fermentation lab should have the substrate in the vessel, and it should be very sterile so no contamination doesn't happen (make sure to label them vessels well). Secondly, the negative control vessel should not be inoculated with the microbe, like yeast, in it at all because you want no response. If there is a response, it could be contamination or you mistakenly inoculated with the microbe which fermented the substrate. Hope this helped you plenty! 😄
How does the motion of the molecules change during melting?
The motion of molecules is accelerated.
Why you should avoid allowing the loop filled with inoculate from touching the lip of either the source bottle or the bottle to be inoculated?
Touching the lip of the bottles can lead to contamination from airborne microorganisms. These microorganisms can affect the purity of the culture and compromise the results of the experiment. Additionally, it can introduce unintended microbes into either the source bottle or the bottle being inoculated, leading to unreliable outcomes.
What kind of weather should you expect in a warm front?
Warm fronts frequently bring blustery climate as the warm air mass at the surface transcends the cool air mass, making mists and tempests. Warm fronts move more gradually than cold fronts since it is more hard for the warm air to push the chilly, thick air across the Earth's surface.
What happens to the surface of a minerals if the acid test is positive?
It should bubble.
Why should you not walk across a snow field in stillettos?
Because the small surface area of the heel will cause you to sink into the snow !
At what angle should you tilt an air table to simulate motion on the moons surface?
To simulate motion on the moon's surface, an air table should be tilted at approximately 5°. This angle is equivalent to the reduced gravity experienced on the moon compared to Earth, allowing objects to move with similar characteristics as they would in a lower gravity environment.

What did the control broth inoculated with Escherichia coli demonstrate?
The control broth inoculated with Escherichia coli should demonstrate bacterial growth as expected. If there is no growth in the control broth, it may indicate issues with the inoculation process, the broth itself, or other experimental variables affecting bacterial growth.
Should you eat mangoes in loose motion?
No,you should not eat mangoes in loose motion because thay provoke Loose Motion
Should you walk your bike across main streets or ride across?
You should almost always walk your bike across the street. If there are nobody else walking across you can ride it across.
Can you respond to a Notice of Motion and Motion for Judgment on the Pleadings?
Yes you should respond promptly
What basic motion should a ship have in order that the rudder will be effective in turning the ship?
It should be moving forwards or backwards.
If you find your brakes failing what should you do?
use your emergency brake if in motion, if not in motion get new brakes!
Why does a rolling ball stop rolling?
Friction translates lateral motion to rolling motion, but it can slow down a rolling ball because it opposes the motion of the ball's lower surface to do so. This removes momentum from the ball.When a ball combines rotational and translational motion (rolls), friction acts in the opposite direction of the motion. This in turn should produce a torque by the frictional force i.e,[u.m.g*R] where R=radius of sphere , u = co-efficient of friction. The torque produced should increase the angular acceleration and therefore the body should rotate with greater speed, but as we know, the rolling sphere stops after a certain time.REASON: When a sphere rolls, the surface in contact with the sphere is depressed and the surface just in front of it is raised. So when the rolling sphere strikes this raised surface, the normal reaction instead of passing from center of mass passes through a little bit away in the forward direction of the motion. Therefore the torque produced by this is greater than the torque produced by the frictional force, and opposes the motion of the body until it comes to rest.
