<span>The correct answer is B. following fitness safety basics. If you follow the guidelines that tell you how you should do an exercise, then obviously there aren't going to be any problems and you won't get hurt. You don't need to have the most expensive equipment, or join the most popular gym, or stay at home in order to do that - you just have to follow the rules because they were made by people who know their job well so there that you don't get injured.</span>
<span>The most common listening problem is A. paying attention but misinterpreting the message. It is a problem that happens all the time - you think that the person you are talking to understands what you are trying to tell them, however, they don't really, and that can cause and issue, or sometimes even a conflict. This is why you need to speak clearly and often ask people whether they understand your message so as to avoid problems.</span>
Hi there!
The nose, diaphram, and lungs are all part of the respiratory system.
The respiratory system's job is to get you breathing; to get oxegon and nitrogen in your lungs and get carbon dioxide out.
Hope this helps!
Based on the results of the study shown below, the epidemiologist has reason to worry because the incidence rate increased over four times the previous level as shown below:
- number of HIV cases = 440 persons
- new incidence rate = 2.25 per 1000 persons
<h3>What is prevalence and incidence rate?</h3>
Prevalence rate is the proportion of persons in a population who have a particular disease or attribute at a specified point in time or over a specified period of time.
- Prevalence rate = number of cases/total population × 100%
Incidence rate is the proportion of new cases of a condition observed within a given period of time.
- Incidence rate = number of new cases/population at risk × 1000
- population at risk = total population - previous cases
The number of people who had HIV in January 2012 is calculated as follows:
- number of HIV cases = prevalence rate × total population
number of HIV cases = 2.2% × 20000
number of HIV cases = 440 persons
Incidence rate between February 2012 and January 2013 is calculated as follows:
Incidence rate = 50/(20000 - 440) × 1000
Incidence rate = 2.25 per 1000 persons.
Based on the new incidence rate, the epidemiologist has reason to worry because the incidence rate has increased over four times the previous level.

Risk factors are attributes at the biological, family,psychological or community level that anticipates and being associated with a negative outcome.Meanwhile, Protective factors are characteristics showing a lower possibility of negative results. It may be identify as positive response. Some factors are considered fixed while others can change.
