Answer:
A) Biochemical test
Explanation:
The complete question is as follows:
You place an inoculum of your bacterium on a glass slide and add a drop of hydrogen peroxide reagent. Promptly you see bubbles appear, 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
- Biochemical testing is a useful method using which one can identify the bacteria upto the genus and species level.
- Each organism identified through biochemical testing has its specific biochemical reaction that acts as a fingerprint for its identification.
- The reason why different biochemical reactions are produced by different bacterial species is because the different species possess their own set of DNA that encodes for unique set of proteins in each of them.
- Therefore, the production of bubbles on addition of hydrogen peroxide in an inoculum of bacterium due to presence of a particular enzyme unique to the bacterium is a type of biochemical identification test.
Before you faint, you feel dizzy. The dizziness is from the light headedness.
1. Balances fluids.
2. Structure. Support for tissues.
Answer:Certain animal behaviors affect that probability. Behavior affects probability of reproduction. Animals have adapted a variety of courtship and mating behaviors to increase the probability of finding a mate. For example, the males of many bird species gyrate their feathers or perform special dances to attract a female.
Explanation:
The cell shrinks because of the movement of water away from the cell into the more concentrated salt solution.
Osmosis is the movement of water from one region to another through a semi - permeable membrane. A hypertonic solution contains more solute than the cell.
In this case, the external salt solution is hypertonic because it contains a 8% salt concentration whereas the cell contains only a 0.9% salt concentration. As such, water moves out of the cell into the solution.
The cell shrinks because of the movement of water away from the cell into the more concentrated salt solution.
