You place an inoculum of your bacterium on a glass slide and add a drop of hydrogen peroxide reagent. Promptly you see bubbles a
ppear, indicating the presence of a particular enzyme that the bacterium produces. What type of identification test does this exemplify? A) Biochemical test
B) Immunochromatography
C) Microarray
D) Precipitation test
In microbiology biochemical test is used to examine the metabolic activities performed by bacteria to identify that microorganism. So in biochemical test enzymatic reaction of cell is usually investigated because there is difference in enzymatic activity of different species of bacteria.
For example, catalase test that is used to differentiate between catalase-positive and catalase-negative bacteria is an example of biochemical test. Catalase-positive bacteria have the catalase enzyme that breaks hydrogen peroxide into water and oxygen which is confirmed by bubbles that appear on glass slide.
Catalase negative bacteria do not form bubbles when they are put in hydrogen peroxide which shows that they lack catalase enzyme. So the right answer is A.
During labs eating is a big no. Some food can catch on fire, or be contaminated or breed germs that can affect the experiment. Wearing googles is a good idea and tying back hair is a must when using fire. The work area should always be clean so A is the answer
it's a summary of the number of individuals of each age in the population. Age structure is useful in understanding and predicting population growth. An understanding of population age structure is critically important to industries that harvest living organisms.
The
correct answer is RNA.
<span> The
central dogma explains the flow of genetic information within a biological
system. It is a simplified explanation for a gene expression. DNA is copied
into mRNA during the process of transcription and the proteins are synthesized
using the information in mRNA during the translation.</span>
