Students are encouraged to handle, manipulate, observe, and measure the skull specimen in a format of discovery learning.
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.
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.
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.
A common attribute in all experiments is the control treatment, where one or more independent variables are manipulated to observe their effects on one or more dependent variables.
The Anonymous (2012a) study involved a quasi-experimental 2 × 4 factorial research design combined with non-equivalent comparison or control group design that was manipulated to observe and analyse the variables.
These results suggest that although in vitro conditions could be manipulated to observe bypass of N-dA PCLs by pol δ, the block to replication is likely to occur when pol δ encounters such bulky lesions; therefore, specialized pols may be recruited to carry out TLS.
Optical tweezers are used to manipulate and observe mechanical properties on the nanometer scale and piconewton force range.
Axel's team uses genetics to manipulate and observe neurons in the brains of flies, and there are thousands of different genotypes in the lab.
"The format that most fully exploits the properties of digital environments is not the hypertext or the fighting game but the simulation: the virtual world full of interrelated entities, a world we can enter, manipulate, and observe in process".
