The diagram below represents the structure of the plasma membrane. How would the exchange of molecules between an organism and its environment be affected if the membrane were less permeable? 1. Fewer membrane proteins would be needed to carry out active transport of nutrients.
2. Molecules needed for growth would have more difficulty diffusing across the membrane.
3. Organisms would be more susceptible to harmful substances crossing the membrane
4. The membrane would rearrange to form a single phospholipid later to transport materials

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.
