You have examined several body systems that rely and work with each other in order function properly. one very important task that amphibians and all living things need is to efficiently exchange gases in order to survive. explain in a brief essay how the cardiovascular system and respiratory system work with each other based on your experience and observations from this virtual lab.

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.
