The given question is incomplete. The complete question is as follows;
The number of bacteria in a certain population is predicted to increase according to a continuous exponential growth model, at a relative rate of 16% per hour. Suppose that a sample culture has an initial population of 71 bacteria. Find the predicted population after three hours Do not round any intermediate computations, and round your answer to the nearest tenth bacteria
.
Answer:
114.7
Explanation:
A (t) represent the population of the bacteria at the time t.
Since, the population grows exponentially, the population can be calculated as follows:
A (t) = Ao × 
A (t) is teh final population, Ao is the initial population, e is the exponential, k is rate and t is time.
A (t) = 71 × 
For t = 3 hours
A (t) = 71 × 
A (t) = 114.7.
The population of bacteria after 3 hours is 114.7.
It is called a population since they are all the same species

Answer:
All these are emerging infectious diseases.
Explanation:
The emerging infectious diseases refer to the infections, which have appeared freshly within a population or those whose occurrence or geographic range is enhancing briskly or is threatening to upsurge in the coming time. The emerging infections can be a result of:
1. Known agents, which have dispersed to novel geographic locations or new populations.
2. Previously unknown or undetermined infectious agents.
3. Previously known agents whose function in particular diseases was not determined previously.
According to WHO, infectious diseases are emerging at a rate, which has not been noticed before. Since the 1970s, many infectious diseases have been discovered like Ebola, SARS, avian influenza, mad cow disease, and West Nile encephalitis.
With the individuals traveling much more to far greater distances in comparison to the past, encountering with wild animals, and living in more densely populated regions has caused the emerging infectious diseases to spread briskly and is resulting in global epidemics, which is a major worry.
