If
e. coli in a culture double every 20 minutes what would happen to the amount of hemoglobin that the culture could produce

It would increase exponentially

Explanation:

Based on the information given, the E. coli cells will double every 20 minutes. Assuming that these cell has a plasmid that will allow it to produce haemoglobin under the right conditions, and these conditions are met. The amount of protein that can be produced will also double. This factor is not occurring indefinitely as the bacterial cells will eventually run out of food and the very product that they are creating may become toxic.

Typically, E. coli  cells will multiply exponentially and a typical optical density (O.D.) for harvesting or stopping the growth is 0.6 to 0.8. This is usually around 12 to 16 hours.

answer; i believe is(b)converging

the answer for this question would be d. glaciers
