The conclusion that can be made here is that:

  • A is motile
  • Specimen A gave indole
  • Specimen B does not hydrogen sulfide (H2S)
  • Specimen B does not have indole

<h3>What is a sim media inoculation?</h3>

This is a type of laboratory practical that isb used to see if organisms are motile through the use of single stabs.

An organism is motile when there is a radiation from the stab mark which makes the tube it is in to turn turbid.

Complete the sentence using weathering, erosion, or deposition.
Lesechka [4]

Answer: Erosion

Explanation: This is because the process of moving sediment after they have formed would be considered the destructive process of erosion. Erosion is the act of moving sediments before they are formed or during, and weathering is similar to erosion but doesn't neccesarily have to do with Gravity because it focuses on the elements rather than the physics of mother nature.

Which diagram best illustrates what happens when electromagnetic waves strike a rough, dark material?
muminat
When electromagnetic waves strike an obstacle, what usually happens is that part of the wave is absorbed by the obstacle, part is reflected back and part is transmitted through the material.
However, in case of a dark object; the dark object acts as a perfect absorber and absorbs all the electromagnetic waves.
So, the right answer is the diagram showing only absorption of the wave by the surface.

Which of the following elements would be more reactive with other elements
kirza4 [7]

Answer:

The chemical element which would be the most reactive with other elements is: D. helium, #2.

A chemical property is a property of a chemical substance that is observable and measurable in the course of a chemical reaction. The chemical properties of a chemical substance include the following:

  • Tarnishing.
  • Heat of combustion.
  • Flammability.
  • Acidity.
  • Chemical reactivity.

Chemical reactivity is a property that determines how readily a chemical element would bond with other chemical elements to form a new compound.

Basically, the ability of a chemical element to bond with other chemical elements is highly dependent on the number of valence electrons.

The chemical elements Neon and Argon are noble elements, and as such have a filled outermost shell and wouldn't react with other chemical elements.

Helium has a single valence electron in its outermost shell while Boron has three (3) valence electrons in its outermost shell.

In conclusion, Helium with an atomic number of two (2) would be the most reactive with other elements.
