Question

Please answer all

12) Generation time refers to: (1 pts) the number of generations present after a specific time interval has elapsed. the time required for a cell population to reach the logarithmic phase. the time required for a cell to divide or a population of cells to double. the time at which a cell population reaches its maximum number. the time required for a cell population to achieve balanced growth. 13) When an organic compound serves as a final electron acceptor, the process is (1 pts) called: aerobic respiration O anaerobic respiration O fermentation Oglycolysis. 14) Amylase (diastase) is an (1 pts) O exoenzyme. endoenzyme. (1 pts) 15) Indicate whether eosin methylene blue agar is a selective or differential media by marking the appropriate box(es). If the medium is both selective and differential, mark both. If the medium is neither selective nor differential, check the "neither" box. O selective differential O neither

Answer 1

12) Option 3 is correct.

The time required for cell to divide or population of cells to double. The generation time is sometimes known as doubling time, which means the average time taken for a population of cells to become double. It is the average time betweent he two generations.

13) Fermentation

The final electron acceptor which is organic molecule happens in fermentation. This may be pyruvate or acetaldehyde, etc.

14) Amylase is an exozyme.

It is secretred by the cells, and cleaves the starch molecule, outside the cell.

15) Eosin methylene blue agar is both selective and differential medium.

It uses both dye indicators, and it inhibits the growth of many Gram positive organisms.
