Document Summary

Slide 15: unable to do those thing without a host. Slide 16: cell separate the internal from the external. Slide: 17: energy: pumping chemical in and out of the cell. Slide 18: maintain life; speration between internal ans external. Fertill organism are favored because they could reproduce and extent there population. Slide 19: respond to stimuli is favored by natural selection. Slide 21: development of more careful ways to monitor internal ans external enviornemnt. Different virus vs unicellular: virus need a host, bacteria can reproduce, ect. Slide 22: evolution change is an outcome to better reposnd to external environment. Change in external environment cause animal to evolve in order to better suit the enviorenment. No change in environment would not spefically change the animal traits. Parasite vs virius use host as an environemtn but not hijacking the dna of the host. Slide 23: virus evolve only inside a host.
