Trimethoprim-sulfamethoxazole (sxt) disks are used with bacitracin disks to differentiate which streptococci

The correct answer is - β-Hemolytic streptococci.

Explanation:

Beta hemolytic or complete hemolysis termed on the characteristic of the complete lysis of red cells due to the enzyme streptolysin, under the colonies. These are leads to the particular area to be transparent and lightened.

Beta hemolytic streptococci are one type of beta-hemolytic bacteria that are fall in group A streptococci, these bacteria produce an exotoxin enzyme. Bacitracin with trimethoprim-sulfamethoxazole disks is used to differentiate these streptococci.

Thus, the correct answer is - β-Hemolytic streptococci.

answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
