While swabbing objects to sample bacteria, you want to create a negative control to ensure that you are practicing proper asepti

c technique. You place an applicator in the sterile broth, and spread it on an agar plate without swabbing any surfaces. Which result would yo see from a properly prepared negative control?.

The result which would be seen from a properly prepared negative control is nothing.

<h3>What is a Negative control?</h3>

This type of control  is used to test and ensure that in the absence of the antigen we do not still get a positive reaction.

Since proper aseptic technique was practised and there was no swabbing of the surface then there would be nothing seen in the properly prepared negative control.

How do cricket communicate temperature and reactions and body parts allow them to do this?
aleksley [76]

Answer:

as temperature rises, mussles in a crickets body contract more, causing it to chirp more often

Explanation:Crickets, like all living things, have many chemical reactions going on inside their bodies, such as reactions that allow muscles to contract to produce chirping. Crickets, like all insects, are cold-blooded and take on the temperature of their surroundings. This affects how quickly these chemical muscle reactions can occur. Specifically, a formula called the Arrhenius equation describes the activation, or threshold, energy required to make these reactions occur. As the temperature rises, it becomes easier to reach a certain activation energy, thereby allowing chemical reactions, such as the ones that allow a cricket to chirp, to occur more rapidly.

An air pressure of 1,005 millibars is equivalent to approximately how many inches of Mercury?
N76 [4]

1005milibars of pressure corresponds to 29.68inches of mercury.

Option D.

<h3><u>Explanation:</u></h3>

Mercury has a density of around 13.6gm/cc. Thus the pressure of inches of mercury will have a huge effect on the value. As far as bar is concerned, it's around the normal atmospheric pressure measured at sea level. Its around 1,00,000 pascals. So from converting a pressure at millibars to inches of mercury, we need to divide the value by a factor of 33.864.

So, pressure in milibars =1005milibars.

So, pressure in inches of mercury = 1005/33.864 = 29.68 inches of mercury.
