<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
False, the aorta is the major artery that takes oxygenated blood from the heart to the rest of the body.
Answer: Visualizing Transcription
Explanation:
DNA is double-stranded, but only one strand serves as a template for transcription at any given time. This template strand is called the noncoding strand. The nontemplate strand is referred to as the coding strand because its sequence will be the same as that of the new RNA molecule.
Answer:
B) Digestion is the process of breaking down food into smaller molecules.
Explanation:
The correct answer for the given statement above would be FALSE. Understanding the salinity of aquatic environment is IMPORTANT in understanding the overall ecosystem. Salinity<span> has a huge effect on what species can exist in </span>aquatic environments. The amount of salt present in the water can determine the impact of living organisms present on that area. Salinity can disrupt the entire food chain within an aquatic ecosystem. Hope this answer helps.<span>
