Answer:
Gas:
- assumes the shape and volume of its container
; particles can move past one another
- compressible
; lots of free space between particles
- flows easily
; particles can move past one another
Liquid:
- assumes the shape of the part of the container which it occupies
; particles can move/slide past one another
- not easily compressible
; little free space between particles
- flows easily
; particles can move/slide past one another
Solid:
- retains a fixed volume and shape; rigid - particles locked into place
- not easily compressible
; little free space between particles
- does not flow easily
; rigid - particles cannot move/slide past one another
Particles in a:
1. gas are well separated with no regular arrangement.
2. liquid are close together with no regular arrangement.
3. solid are tightly packed, usually in a regular pattern.
Particles in a:
1. gas vibrate and move freely at high speeds.
2.liquid vibrate, move about, and slide past each other.
3. solid vibrate (jiggle) but generally do not move from place to place

<h2>Gelatin </h2>
Explanation:
Gelatin is a differential medium which tests the ability of an organism to produce an exoenzyme, called gelatinase (this enzyme hydrolyzes gelatin)
When gelatin is at a temperature below 32°C (or within a few degrees thereof), it is a semisolid material and at temperatures above 32°C, it is a viscous liquid
When gelatin is broken down, it can no longer solidify and if an organism can break down gelatin, the areas where the organism has grown will remain liquid even if the gelatin is refrigerated
No the conclusion by student is not right because the tube must be runny after incubation followed by refrigeration to be considered gelatinase positive
i believe the answer u might be looking for is number 3. plants breathe carbon dioxide, so an increase in plant life could help aid world hunger.
Yes. It does in fact.
