As described in lecture, cells form actin filaments in particular regions of the cell in part because they nucleate filament formation at particular times and places within cells and in part because they inhibit the formation of filaments that are "randomly" nucleated. What protein(s) is/are responsible for inhibiting the elongation of filaments that are randomly nucleated?a. Profilin
b. Thymosin B4
c. Tropomodulin
d. Formin
e. CapZ

Which term describes the number of waves that pass a given point in a given time? crest frequency trough wavelength

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.
