Why petriplates keep in inverted position in incubator for bacterial growth?
Siju234
There is always some water condensation on the inside of the lid if it's kept in the 'regular' position. If water drips back to the culture the indivodual bacterial colonies will wash together. Inverted incubation prevents that.

Why the inoculated agar medium plate must be inverted position in incubator?
Moisture in the air condenses on the lid of the plate and drops on top the agar if the plates are place right way up. The falling water droplets will spread the bacteria and especially ruin streak plates and spead plates where you need clear distict separate colonies.
If images focused on the retina are inverted how do you see the worl in its proper perspective?
You see objects because they reflect light rays. As light travels to your eyes, the lens focuses the image of the object on the retina. The image of the object in the retina is inverted. As the image is formed, the optic nerves send the message to the brain. It is the brain that interprets and corrects the inverted image into an upright position. - Science Links by Sugpatan, Parde and Apolinario
Predict the outcome of incubating inoculated streak and pour plates in the upright rather than the inverted position?
it will not minimize water evaporation, and it would be easier for contamination to take place
When is the shape of an position versus time graph parabolic?
If a position versus time graph is parabolic, then:Speed versus time is a straight line.Acceleration (magnitude) vs time is a horizontal line, so the acceleration is constant.The graph of height/time for a stone or a baseballtossed upward is an inverted parabola.
What is the meaning inverted position?
Inverted position means the object was turned inside out or upside down.

What happens when light is passed through two similar prisms placed in inverted position?
It is spread out into a spectrum, then recombined into white light.
Why is it important to determaine the location of the endospore?
Bcause the position of the endospore differs among bacterial species and is useful in identification.
What are inversions according to music?
In Music, we speak of inverted intervals, chords or phrases. An inverted interval is just like an inverted fraction. It's upside down. Think of a fifth, C on the bottom, G on the top. Now put the G on the bottom and the C on the top. An inverted fifth becomes a fourth and vice versa. An inverted third becomes a sixth and vice versa. Think of a regular triad in root position: root, third and fifth. If you put the third as the lowest note, we call that the first inversion. If you put the fifth as the lowest note, we call that the second inversion.
When hanging upside down your nose becomes inferior to your mouth in the anatomical position?
Yes, when inverted (hanging upside-down), the nose becomes inferior to the mouth, compared to being upright when the nose is in the superior position above the mouth.

What does a teeter inversion table do?
A teeter inversion table is a tilting table that secures a person to it so that they can be held in an inverted position (head towards ground) to help alleviate problems such as back pain.
