You discovered a mouse gene with an unknown function. You do not know the location or sequence of this gene in the mice genome, but a similar gene has been isolated and sequenced in yeast. How might you determine whether this gene is essential for development in mice

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.

Why are current extinctions of concern to enviromentalists?

Achange in direction without a change in speed is called velocity
