Hi there!
Sustainability means that something or someone has the ability to keep something going.
For example, a plant could have good life sustainability because it has a special poison, keeping predators away from it.
You could be self sustainable by growing your own crops, collecting your own water, and making things you need.
Hope this helps!
The nurse should obtain the specimen from the catheter.
One of the tests from urinalysis that frequently got contaminated is about infection. The area near the orificium of uretra is near the skin, so there will be microbes around it that can contaminate the sample. The contaminated sample will give a false positive and the result will show the urine are infected.
Taking the specimen from catheter will prevent that contamination, thus giving a better sample.

Hope this helped you!:)
Our genes can be affected by the environment and change the way our traits are displayed, called the phenotype. However, changes in phenotype have an underlying genotypic source. Epigenetics or epigenetic changes are changes in the way traits are expressed as an effect of the environment (i.e. food we ate, chemicals in the body, environmental stresses), without changes in the DNA. Simply put, in epigenetics, some parts of the DNA are turned on or off in response to environmental conditions.
