The rate during which the rate of multiplication is decreasing is also known as Correct Answer Negative acceleration phase

The rate during which the rate of multiplication is decreasing is also known as the Negative acceleration phase.

Key Points

  • The growth rate decrease in this phase so this is called the negative acceleration phase.  
  • In this stage of log stage growth rate decrease because resources start to become limited in this stage. 
  • In this last stage of the growth curve, resources become limited so zero growth occurs in this phase.

Additional Information

  •  Maximum stationary phase
    • ​The stationary phase is the stage when growth ceases but cells remain metabolically active.
    • The characteristic proteins synthesized in the stationary phase are indispensable as they confer viability to the bacteria.
  • Accelerated death phase
    • ​In the death phase, the cells begin to die and the growth rate becomes negative as a result of the lack of nutrients or the presence of poisonous byproducts from the reaction.
  • Survival phase
    • Bacterial growth and survival is dependent upon the ability of an organism to sense its environmental conditions and respond to external stimuli.​

A pipe, working at full speed, can fill an empty cistern in 1 hour. However, during the first hour it worked at one-twenty-fourth of its capacity, during the second hour at one-twelfth of its capacity, during the third hour at one-eighth of its usual capacity, during the fourth hours at one-fourth of its usual capacity and during the fifth hour it was only one-half as efficient as it was supposed to be. A second pipe also displayed similar performance, but if it worked at full speed would have filled the empty cistern in 2 hours. Together with a drain pipe that drained water out of the tank a constant rate, the empty cistern could be filled in 5 hours, all the three pipe working concurrently. How many hours will it take the drain pipe to empty the filled cistern if no other pipe was functioning during the time?

4. A minimum rate of remuneration to apply in the case of employees employed on piece work for the purpose of securing to such employees a minimum rate of wages on a time work basis is overtime rate.
A pipe, working at full speed, can fill an empty cistern in 1 hour. However, during the first hour it worked at one-twelfth of its capacity, during the second hour at one-ninth of its capacity, during the third hour at one-sixth of its usual capacity and during the fifth hour it was only one -third as efficient as it was supposed to be. A second pipe also displayed similar performance, but if it worked at full speed would have filled the empty cistern in 2 hours. Together with a drain pipe that drained water out of the tank at a constant rate, the empty cistern could be filled in 5 hours, all the three pipes working concurrently. How many hours will it take the drain pipe to empty the filled cistern if no other pipe was functioning during the time?

After teaching the concept of multiplication to her class, a teacher asked her children to multiply 48 by 4. One of her students solved it orally as “To multiply 48 by 4, we first add 48 to 48, which makes 96 and then add another 96 to reach 192. So, the answer is 192”. What can you say about his / her strategy of multiplication?
