While C. elegans and its embryos are relatively easily manipulated and observed, and the C. elegans genome has been fully sequenced [ 17], embryos from the Enoplia and Dorylaimia are much harder to culture and manipulate.
Of the many model organisms, zebrafish (Danio rerio) provides unique advantages for studying gene function and vertebrate development, such as significant similarities with humans in genetic information and physiology, rapid ex utero embryo development and reproductive cycles, and the ease with which the large and transparent embryos may be manipulated and observed.
The ease with which C. elegans can be grown, manipulated and observed has driven biomedical research into new areas and 'the worm' has been a silent collaborator in three Nobel prizes, and thousands of research articles over the past 50 years.
In this group, she did not talk to the group members but only observed how other students manipulated the lab materials.
Reanalysis processes may play a role in producing selective activation to complex sentences, as increased activation in LIFG has been observed in studies that manipulated the difficulty of a postsentence comprehension probe (Love et al. 2006; Caplan, Chen, et al. 2008).
If we manipulate some experimental condition and the observed results differ from this expected results, two possibilities are possible: either this happened by chance, or our manipulation of experimental variables caused the difference.
The only exception was one trail ant that was predated upon by a spider (none of the behaviorally manipulated ants we observed were predated upon).
First we observed that APE1 knockdown and overexpression in the RPMI-8226 cells manipulated the MDR1 protein expression level.
Time is the subject, measured and manipulated, felt and observed, by 20th-century composers from John Cage ("4'33" ") to Gyorgy Ligeti ("Symphonic Poem" for multiple metronomes).
