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.
Scientists can learn, which types of organisms were more common during time periods, how species have evolved over time, and the relative age of different species. Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperature and pressures that do not destroy fossil remains. Dead organisms can become sediments which may, under the right conditions, become sedimentary rocks.
Answer:
Sexuality exists on a continuum.
Explanation:
The American biologist, Dr. Alfred Kinsey had incorporated in the Institute for Sex Research. He worked on a series of sexuality studies during the 1940s in Indianan university.
Dr. Alfred Kinsey explained that the sexuality exists on a continuum. The person's sexual orientation generally based on the experience and response at that time.
Thus, the answer is sexuality exists on a continuum.
