- Q1Since bacteria are prokaryotic, they cannot divide by mitosis or meiosis. Therefore, what is the process that prokaryotic cells use to divide?Binary fissionBuddingFragmentationSpore formation30s
- Q2What is binary fission?A process of cell division that results in the formation of gametes.A method of reproduction involving the development of a zygote.A type of sexual reproduction involving the fusion of gametes.A type of asexual reproduction in which a single organism replicates its DNA and divides into two identical daughter cells.30s
- Q3What is the term given to the time it takes a prokaryotic cell, like bacteria, to complete the binary fission cycle?Replication durationCell division timeGeneration timeBacterial growth period30s
- Q4How does generation time affect the onset of symptoms?Longer generation time leads to delayed onset of symptoms.Shorter generation time leads to delayed onset of symptoms.Longer generation time leads to earlier onset of symptoms.Shorter generation time leads to earlier onset of symptoms.30s
- Q5What are the four phases of growth for microorganisms?Log, Log Exponential, Stationary, DecayLag, Decline, Log Exponential, DeathLag, Log Exponential, Growth, DeathLag, Log Exponential, Stationary, Death30s
- Q6During the lag phase of microbial growth, which of the following occurs?A decline in the number of bacteria due to a lack of nutrients.Active replication of DNA and division of cells.Release of toxic substances that inhibit growth of other microorganisms.A period of adaptation where bacteria cells adjust to available nutrients and no growth happens.30s
- Q7What typically happens during the exponential phase of microbial growth?Rapid and constant increase in the number of microorganisms.No growth or increase in the number of microorganisms.Formation of spores to withstand harsh environmental conditions.A decline in the number of microorganisms due to nutrient depletion.30s
- Q8Which of the following is NOT a characteristic of the stationary phase in microbial growth?Balanced rates of cell division and cell death.Production of secondary metabolites or spore formation.Rapid increase in cell numbers.Limited availability of nutrients.30s
- Q9Which of the following is NOT true about the lag phase in microbial growth?Microorganisms are actively replicating their DNA and dividing.Microorganisms are synthesizing enzymes and proteins.There is minimal increase in cell numbers.Microorganisms are adapting to the new environment.30s
- Q10Which phase of microbial growth is characterized by a constant number of viable cells?Lag phase.Decline phase.Exponential phase.Stationary phase.30s
- Q11In this stage of microbial growth cells are most adaptable in this phase since they know what is and is not supposed to be in their environment. As such this is the stage where cells may enter the endospore stage of survival since they are acutely aware of what to expect of their environment.Log Exponential PhaseStationary PhaseDeath PhaseLag Phase30s
- Q12During the death phase of microorganism growth, which of the following occurs?Growth rate is higher than death rate.Growth rate and death rate are equal.No growth or death occurs.Growth rate is slower than death rate.30s
- Q13What causes bacteria to be more susceptible to antibiotics during the log phase?Increased resistance genes expressionHigh mutation rateLow metabolic activityRapid cell division30s
- Q14Which of the following is NOT an environmental condition that affects the growth rate of bacteria?Genetic makeupTemperatureMoisturepH30s
- Q15What is the term used to describe the condition at which bacteria grow at their fastest rate?Neutral conditionMaximum conditionOptimum conditionMinimum condition30s
