Micropipettes are routinely used in biology and chemistry labs to transfer small volumes of liquids. Other instruments can also be used to measure liquids in the lab, but the micropipette is best to transfer very small quantities such as .001 mL (one microliter or 1 L.) You will save time and energy as well as gain confidence by completing the exercises that follow before you come into lab.
Quantitative, Qualitative, and Mixed Research. This chapter is our introduction to the three research methodology paradigms.

basic research because the studies are looking at the fundamentals of how things work and interact; preclinical research because the research is conducted prior to research in people in the clinic or in clinical trials; Human studies There are several different types of research studies that involve humans. These include clinical trials and observational studies. Systematic reviews summarize the results from many different clinical trials and observational studies, and meta-analyses pool data collected from multiple smaller studies in addition to including a systematic review.
