Question

a communicable disease that can be easily transmitted from person to person is which type of disease?
iadtrogenic
nosocomial
acute
contagious
question 10 (1 point)
which of the following is the best definition of generation time in a bacterium?
the time it takes to reach stationary phase
the length of time of the exponential growth phase
the length of time it takes to reach log phase
the length of time it takes for a population of cells to double

Explanation:

First Question (Disease Type)

To determine the type of communicable disease easily transmitted person - to - person, we analyze each option:

• iatrogenic: These are diseases caused by medical treatment or procedures, not related to easy person - to - person transmission.
• nosocomial: These are infections acquired in a hospital or healthcare setting, not defined by easy general person - to - person transmission.
• acute: Refers to the duration of a disease (short - term, severe), not its transmissibility.
• contagious: By definition, a contagious disease is one that can be easily transmitted from person to person.

To find the best definition of bacterial generation time, we analyze each option:

• "the time it takes to reach stationary phase": Stationary phase is about growth cessation due to limiting factors, not related to generation time.
• "the length of time of the exponential growth phase": Exponential growth phase is a growth stage, and generation time is not the length of this phase.
• "the length of time it takes to reach log phase": Log phase is a growth phase, and reaching it is not what generation time measures.
• "the length of time it takes for a population of cells to double": This is the standard definition of generation time in bacteria, as during growth, the time for the population to double is the generation time.

Answer:

D. contagious
