Answer:
Explanation:
Simulation is imitating a process. It is doing exactly like a system will do. It can be used in technologies, education, health, training,
safety engineering. Simulation can be used when the original or exact system is not in place, or cannot be accessed.
A model is a process that helps to understands a system. A model is like an example to follow in achieving a result. A model may not be followed judiciously such that you may require an aspect of the model and then use but not necessarily all attributes while a simulation does exactly what the system does.
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.
Answer: Mammalian red blood cells have a biconcave (doughnut-like) shape. If red blood cells are placed in a 0.3 M NaCl solution, there is little net osmotic movement of water, the size and shape of the cells stay the same; the NaCl solution is isotonic to the cell. If red blood cells are placed in a solution with a lower solute concentration than is found in the cells, water moves into the cells by osmosis, causing the cells to swell; such a solution is hypotonic to the cells. When red blood cells are placed in pure water, water rapidly enters the cells by osmosis and causes the cells to burst, a phenomenon known as hemolysis. If the red blood cells are placed in a solution with a higher solute concentration, water moves out of the cell by osmosis, the cell becomes smaller and crenated in shape; such a solution is hypertonic to the cells.
the answer is A. an amoeba
They had no heat to keep their pipes unthawed. I live in Minnesota and frozen water/ burst pipes ain't no joke lol. That sucks
