5)Flame lip of broth culture tube.
6) Dip loop into sterile TSB and swirl. Remove loop.
7)Flame lip of broth culture tube.
8) Sterilize the loop.
Explanation:
The aseptic technique is a s<u>eries of steps to prevent contamination during manipulations of cultures and sterile culture media</u>. A mastery of aseptic technique is required for maintaining pure cultures, as airborne contaminants are virtually everywhere. Picking an isolated colony and restreaking it is the main method for obtaining pure cultures from liquid samples containing several different organisms and is a common procedure in the microbiology laboratory. Other techniques for obtaining pure cultures have been developed that are especially suited for particular groups.
<span>Enzymes are Biological Catalysts. They increase the rate of Metabolic reactions. Almost all Biological Reactions involve Enzymes. All enzymes are Globular Proteins with a specific Tertiary Shape. They are usually specific to only one reaction.</span><span>The part of the Enzyme that acts a Catalyst is called the Active Site. The rest of the Enzyme is much larger and is involved in maintaining the specific shape of of the Enzyme.</span><span>When a reaction involving an Enzyme occurs, a Substrate is turned into a Product. The Substrate can be one or more molecules. The Active Site of an Enzyme is Complementary to the Substrate it catalyses.</span>
Answer:
The phenotypic variation for the trait is continuous
Explanation:
Genetically speaking, quantitative traits are controlled by many genes, classes are not easily distinguishable and there is a continuous distribution of the phenotype. These characteristics refer to measurements of quantities (weights, volumes, measurements: kg, m, cm, g, m2, etc.).
In other words, quantitative characteristics are those that exhibit continuous variations and are partly of non-genetic origin; that is, they are greatly affected by the environment.
