Do mutations always lead to evolution? Yes, because mutations create adaptations that give a competitive advantage.

No, because most mutations lead to death of the organism.

No, because some mutations happen in the body cells, so they are not passed on.

Yes, because there would be no change in populations without mutations.

In terms of alternation of generations, the internal parts of the pollen grains of seed-producing plants are most similar to a ) moss sporophyteb) moss gametophyte bearing both male and female gametangiac) fern sporophyted) fern gametophyte bearing only antheridia

The changes that the students observed, rapid breathing and sweating, would be classified as a to a change in a system.

Aspecies has evolved an asexual mode of reproduction by having offspring develop from unfertilized eggs. which of the following will be true of this species' response to natural selection? there will be more deaths from natural selection because there is no mutation. there will be less genetic variation from recombination and a risk of not adapting quickly to environmental change. the species will increase in numbers because genetic variation is increased. the species will compensate for loss of genetic variation by hybridizing with other species. there will be fewer deaths from natural selection because sexual recombination always leads to extinction.
