Answer:
LD50 (median lethal dose)
Explanation:
- Whenever one needs to quantify the virulence of a pathogen then this is done by using a set of laboratory animals.
- LD50 (median lethal dose) is an important indicator of virulence.
- LD50 is defined as the number of pathogens that are required to kill 50% of the total infected animals.
- For the calculation of LD50, the animals are infected with a known number of pathogens and then a graph is plotted for the percentage of animals killed against the concentration of the pathogen used for infection.<em> The point at which the graph indicates the death of 50% animals, the corresponding concentration of inoculation of a pathogen is taken as the LD50 of that particular pathogen. </em>
Answer:
allows the recombination of genetic information
Explanation:
Crossing over is a process that occurs only in meiotic division in sexually reproducing organisms. It is the process whereby the segments of a gene are exchanged between the non-sister chromatids of homologous chromosomes.
Due to this crossing over process that occurs in prophase I of meiosis, the alleles of a chromosomes are recombined to ensure genetic diversity. Hence, according to this question, crossing over results in additional genetic variation during meiosis because it allows the recombination of genetic information.
Kombucha and root beer are two foods produced in other country using fermenatation.
<h3><u>Explanation:</u></h3>
Kombucha is a very popular Asian drink that is actually a slightly fermented and slightly alcoholic green tea. Black tea can also be used. This gives a sweetened and spicy flavour of the tea along with the refreshment of tea. Its fizzy to taste, and can have several flavorings added to it.
