3. changing how long you run after a foot injury - feedback
5.understanding that you'll still be exercising in five years - lifelong process
1. change
The natural selection is a process that occurs as a direct consequence of the living conditions in the environment. When the environment starts to change though, the organisms that live in it face a big challenge. They either have to change, adapt to the new conditions, and thus survive, or if they are not able to do so, to die out. This is the biggest evolutionary pressure for the organisms, and while some come out as winners from it, many others die out .
2. variation
In order for the process of natural selection to occur, the population needs to have some genetic variation. The environment is the ultimate push factor, but if the population doesn't have genetic variation in it, than the species will die out. The genetic variation is very important as in that way the individuals choose who will they mate with, in accordance with their traits, so that only the advantageous traits can be passed on to the next generation, so that it can be more competitive in the environment.
3. traits
The natural selection is a very simple process. The individuals of a population, when choosing a mate, look for the individuals that exhibit traits that are advantageous for survival. Mating with individuals with traits that are advantageous guarantees that the offspring will inherit those traits, thus it will have higher chances to survive. The individuals that do not have advantageous traits though will be avoided as mating partners, and that would rapidly lead to their decline and elimination from the gene pool, as they will not have any offspring to continue their line.
Answer:
Besides playing various roles in daily life, technology also plays roles in preventing and treating different diseases. Flu can be prevented by the use of technology in several ways:
- Use of web to find out latest vaccines and their availability: Vaccines for flu also called flu shots are recommended by doctors in order t stay away from flu as much as possible, web services are efficient source in this regard that help to search for available vaccines and trend of flue in particular areas.
- Quicker diagnostic results: Technology has developed such rapid diagnostic tests that give results within minutes. Like screening test for qualitative analysis of flu have been made and such tests have been developed that are easy to carry out just by single nasal swab.
- Air filters and UV bulbs: To prevent the germs inside the home or closed environment, use of air filters like HEPA filter and UV light is trending. HEPA (high efficiency particulate air) filter the air at great extent thus preventing the germs to spread, and UV light has characteristic to be antimicrobial so it is also installed to kill pathogenic microbes.

Brian uses ultrasound technology to create images of a patient’s liver and kidneys.
Nigel performs tests on a patient to get information about how his heart is working.
Krystal analyzes X-rays to determine whether a patient has a broken arm.
