The box would stay at rest where it lies since the same amount of force is pulling it in opposite directions :)
Answer:
- use of economical model organisms
- collaborating with other scientists with same interests
Explanation:
Using the field of biomedical research as a case study, scientists navigate through limited funding by:
1) trying their investigations on cheaply and readily available organisms such as yeast or worms like C. elegans rather than more complex and expensive higher organisms like wistar rats or Guinea pig
2) forming alliance with other notable scientists in nearby laboratories equipped with a resource or more that is unavailable insitu (at the main research lab)
