Exercise 1 1- Eukaryotic cells, like bacteria and archaea, have a genuine nucleus that is larger than prokaryotic cells. 2- Domain 3-species Exercise 2 1- microevolution are Mosquitoes have developed in reaction to global warming, and insects have acquired resistance to pesticides. 2- Macroevolution is evolution on a grand scale Family tree tutorial 1-phylogeny 2-a clade 3-archaea, bacteria, Eukarya. Understanding phylogenies 4-the roof of the ancestral lineage 5- descendants of ancestor 6-a clade may include many thousands of species. 7-ape ancestor. 8-characters are heritable traits that can be compared across organisms. 9-a shared character is one that two lineages have in common. And a derived character is one that evolved in the lineage leading up to a clade. 10-characters in different organism that are similar because they were inherited from a common ancestor that also had that character. 11- they have separate evolutionary origins. 12-the evolution process which modern organisms have descended from ancient ancestor. 13-testing hypotheses about evolution. -learning about the characteristics of extinct species and ancestral lineages. -classifying organisms. 16-kingdom, phylum, class, order, family, genus, species. 17- the standard system of classification in which every organism assigned to a kingdom. 18-Radiometric dating. -stratigraphy. -molecular rocks. Exercise 3 1-B- a continuous line of descent. 2-d all of the above 3- 4- 5- 6- 7-parrot. 8- 9- Sharks and all other vertebrates share a number of qualities in common, but one feature that sets sharks apart from the rest is their Cartilaginous Skeleton. 10- They are members of the Animalia Kingdom. -They are members of the Chordate Phylum. 11-c 12-c 13- Character shark tuna frog human Hare caiman Parrot T.rex Vertebrae Bony + 0 + + + + + + + + skeleton Four 0 0 + + + limbs Aminiotic 0 0 0 + egg Hair Opening 0 0 0 0 0 0 + 0 in front of eye. + + + + + + + + + + + ? + 0 0 + 0 + ? + 14Character heel Bipedal 4th and 5th finger lost Caiman + 0 0 parrot 0 + + T.rex 0 + + 15-chicken 16- a- yes, Because the common ancestor of the caiman and the parrot had amniotic eggs, T-rex had them as well. This means that the T-rex, the caiman, and the parrot all inherited the characteristic. b- warm-blooded c- most of them do have it d- scientist think that T.rex do have vision how like descendants’ bird and ancestors’ crocs do. e- four chambers f- Yes, T-rexes sing to their young since their common ancestor, the Caiman, also sings to his children. The T-rex, the caiman, and the parrot all inherited the feature in this method.
