THIS USER ASKED ๐
Bacterial growth curves typically can be divided into four distinct phases: lag phase, log phase, stationary phase, and death phase. drag the following descriptions to the appropriate location on the bacterial growth curve. 1- log of the number of bacteria 2- period of most rapid growth. number of bacteria is increasing exponentially 3- bacteria are metabolically very active, but the numbers are not increasing. 4- population growth has halted. number of new cells formed balances the number of cells dying. 5- time 6- rate of the cells death exceeds the rate at which new cells are being formed. number of cells decline exponentially.
THIS IS THE BEST ANSWER ๐
weak step
Bacteria are metabolically active, but the numbers are not increasing
hollow step
The fastest growing period. The number of bacteria is increasing exponentially
stop step
Population growth has stalled. The number of newly created cells equals the number of dying cells.
stage of death
The death rate of cells exceeds the rate at which new cells are forming. The number of cells decreases exponentially.
Explanation:
The bacterial growth curve has four distinct stages –
a) Delay phase – In this phase cellular activities take place but the cell does not grow. Cell size also grows but no cell division occurs
b) log phase – In this step the cell begins to divide by the binary fission process and begins to duplicate the numbers. Metabolic activity is at high speed to prepare the cell for DNA replication.
c) stop phase – After full growth the population begins to decline due to depletion of nutrients and accumulation of waste products.
d) stage of death – At this point the quantity of waste becomes higher than the nutrients and thus the cell begins to die larger.
