Answer:
Biosafety level 3 requires at least two-door separation between the area where biohazards are used and the personnel not associated with the research, requires inward inflow into the lab and must have a visual mechanism to verify that air is flowing in the appropriate direction

Biosafety level 3 is required for clinical, diagnostic, teaching, researching or production laboratories working with microbes that are also following BSL-1 and BSL-2 but as these pathogenic agent can lead to life-threatening disease by inhaling it, besides other contaiment precautions, the BSL-3 facilities must have a separated entrance to laboratory door with unrestricted traffic flow and the lab must be behind two sets of self-closing doors and windows must be sealed, with a ventilation system properly directioned installed.
<u>Three strategies that artists began using to make their work more realistic:</u>
The three strategies that artists began to use to make their work more realistic included perspective, representation or impressionism and abstract art.
- Perspective was used as a technique to depict spatial distance as a realistic illusion. In this technique, the closer objects appeared larger whereas the objects that were behind were smaller. The perspective technique took into consideration the distance of the object from the viewer.
