This instrument has made it possible for scientists to observe certain objects and processes that would otherwise never have been seen with the naked eye or a common magnifying glass, because they are more stable and can be built with greater magnifying power, so that smaller structures can be seen and studied. It is used in a wide range of scientific fields, and has contributed to major discoveries in biology, medicine and materials research. What is the instrument?

Charles darwin published his theory of evolution in 1859. in what way foes modern evolutionary theory differ from the theory as proposed by darwin? a) darwin inferred that individuals can evolve, but modern generic science has shown that this is not true. b)darwin inferred that individuals do not evolve, but modern genetic science has shown that this is not true. c)modern science has disproved most of darwin's original theory of evolution, because darwin knew nothing about generations and their role in heredity. d)generic studies have shown that gene expression and other factors operate along with natural selection, but most of darwin's theory has been supported by modern science.
