PCR, polymerase chain reaction, is the fastest way to artificially (in a laboratory) multiply few copies of DNA into many, in order to create enough of a sample to use for other genetic testing.
It is used quite often in forensic science, such as magnifying a small recovered sample of DNA from body fluids or tissue samples at a crime scene, into a vastly greater quantity of DNA for identification of suspect(s) or victim(s).
The variety of different ways in which species within an ecosystem perform "jobs" that benefit the ecosystem and make it more resilient in the face of change is called ____________.

The REM, or Rapid Eye Movement phase, which is crucial to fostering creativity, improving the quality of sleep, and allows for the creation of long-term memories.
I think it's a.25 because if it holds 40g but has 10g then the 10g is about 25 percent because:
4g = 10 percent
2g = 5 percent
So to get to 10g you have to do 4+4+2, which is 10+10+5 percent which= 25percent. Hope I helped!
