Answer: Glucose
Explanation:
The carbon dioxide produced in the experiment can be directly related to the energy generated after the fermentation process. The carbon dioxide is the byproduct of the chemical reactions in the ethanolic fermentation. Glucose substrate will yield the highest energy along with the highest producer of the carbon dioxide after the fermentation process conducted by yeast as compared to the fermentation process that was conducted by yeast with flour. The flour will offer a source of carbohydrates including starch and sugars. The yeast will find out sugar in the flour and ferment it. Glucose is readily available sugar for the action of yeast so more production of carbon dioxide is expected from glucose substrate.

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:
XYY, spermatogenesis.
Explanation:
Non disjunction may be defined as the phenomena in which the sister chromatids are unable to separate during the cell division. Non disjunction can occur in both meiosis and mitosis.
The determination of non disjunction is not possible. But the XYY condition in an individual might occur when the homologous chromosomes of Y are unable to separate during the process of spermatogenesis as Y chromosome is present in males only.
Thus, the correct answer is XYY and spermatogenesis
