Absence of oxygen means anaerobic respiration ; which has 2 different pathways.
First Pathway ; Alcoholic fermentation which takes place in yeast.
Pyruvate is decarboxylated into ethanal releasing co2 as waste product.
Ethanal is toxic , so its reduced by help of NADH to ethanol in presence of alcohol dehydrogenase enzyme , and Free NAD is released to continue glycolysis.
2) The second pathway is Lactic fermentation which takes place in mammalian muscles.
Pyruvate accepts hydrogen and is converted to lactate by the help of enzyme lactate dehydrogenase , again free NAD is released to continue glycolysis.
Hope I made it clear enough :)
If you want to grow up a large quantity of streptomycin-resistant E. coli, you would require to pick a colony of the bacteria from the streptomycin-positive plate and allow to grow it on a streptomycin positive plate.
<h3>What is E. coli?</h3>
E. coli may be defined as a type of bacterium that is commonly present in the intestinal regions of humans and other animals, some strains of this bacterium can significantly cause severe food poisoning.
The strain of streptomycin-positive is those population of E. Coli which is significantly streptomycin resistant, while the negative strain has the opposite effect.
That's why if you want to grow up a large quantity of streptomycin-resistant, you must remarkably require to pick only a positive strain of streptomycin for E.Coli bacterium.
Therefore, if you want to grow up a large quantity of streptomycin-resistant E. coli, you would require to pick a colony of the bacteria from the streptomycin-positive plate and allow to grow it on a streptomycin-positive plate.

Answer:
Explanation
Given that 36% are recessive in traits
100-36 = 64% for dominant traits considering a whole population to be 100%
P=dominant allele
q= recessive allele
P2= dominant genotype
q2= recessive genotype
according to hardyweinberg principle, p+q=1
64/100= 0.64 frequency for dominant traits or genotype, therefore
p2=0.64
then
P=√0.64
p= 0.8
Therefore, dominant allele frequency (p) for the population is 0.8
Answer:
Can be used for simple experiments at home or in the classroom
The answer is A, anti-fungal drugs.
According to the passage, "but if the problem persists, see a doctor who can prescribe anti-fungal drugs". In additional, at the beginning of the passage, it already stated that athlete's foot is caused by a fungus, so we can sure that the answer is A.
