For example, some inexpensive mowers are designed to have a service life of 200 or fewer hours while pricier mowers typically are designed to last 500 or more hours. Therefore, a lawnmowerâs life expectancy can be based on how often and how long it is used.
exponential growth. Increase in number or size, at a constantly growing rate. It is one possible result of a reinforcing feedback loop that makes a population or system grow (escalate) by increasingly higher amounts. Compound interest is an example of exponential growth. Use 'exponential growth' in a Sentence.
ently distinguished. This is a classical conception, but the different phases have not always been defined in the same way. The follow-ing definitions illustrated in Fig. 1 will be adopted here: 1. lag phase: growth rate null; 2. acceleration phase: growth rate increases; 3. exponential phase: growth rate constant; 4. retardation phase: growth rate decreases; 5. stationary phase: growth rate null; 6. phase of decline: growth rate negative. This is a generalized and rather composite picture of the growth of a bacterial culture.
