The last one is right answer i think
Yes. It is a mechanical process.
<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

See below
Explanation:
A hypothesis theory and a scientific law are starkly different terms. A hypothesis is at a stage where it is tested in a way that either proves it right or wrong. In the case that it is proved right, it goes on further to be replicated by a several other groups of scientists. If the results/conclusions come out to be correct again, it is known as scientific theory - a more detailed explanation for some phenomenon. Further on, this theory will achieve the status of a scientific law when it has been studied in sufficient detail to give a unifying concept about the phenomenon.
Answer:
Answer:Earthquakes often cause dramatic changes at Earth's surface. In addition to the ground movements, other surface effects include changes in the flow of groundwater, landslides, and mudflows. Earthquakes can do significant damage to buildings, bridges, pipelines, railways, embankments, dams, and other structures.
