Unit 3 Study Guide Please, Please, STUDY!!!

Unlock the secrets of fossils! Learn about preservation, evolution, and classification in this engaging study guide.

Using the information from the image above, answer the following question:(1) If a scientist wanted to look for fossils at the ocean, which of the below combinations would have had to have happened for the scientist to be able to find any fossils? hard body parts would have to have been buried in the intertidal zone soft body parts would have to have been buried in the intertidal zone hard body parts would have to have been buried in the deep ocean zone soft body parts would have to have been buried in the intertidal zone (2) Scientist Carolus Linnaeus, said organisms are classified based upon structure family size looks (3) How do scientists know that some mountains were once at the bottom of an ocean? Freshwater rivers flow to the ocean Saltwater fish are found in some mountain streams. Dinosaur bones have been discovered in the mountains. Marine fossils have been found on the peaks of some mountains. FYI...one can assume that the longer you live, the more weight you will put on. Keep this information in the back of your mind as you answer the below question.(4) Dinosaur fossils have been found in different rock layers. The fossils were weighed and the range in weights of the fossils are in the table below.What can be concluded based upon the data in the table? Hint...look @ how the #s overlap each other at the different layers. Dinosaurs with less weight died before dinosaurs with the most weight. Dinosaurs with the most weight had more kids than dinosaurs with the least amount of weight. Dinosaurs weighing 22-50 pounds lived the same amount of time as the dinosaurs weighing 45-80 pounds. Questions 5-12 anatomical relating to bodily structure anatomy the branch of science concerned with the bodily structure of humans, animals, and other living organisms similar having characteristics in common similarity the quality or state of being similar relatedness being related to something biological classification the process by which scientists group living organisms. Organisms are classified based on how similar they are. Theory of Evolution change in the characteristics of a species over several generations and relies on the process of natural selection. genetic diversity Allows species to better survive environmental changes Question 13Below are pairs of anatomy parts, which have been labeled with letters. Decide which letters have anatomy parts that are similar and which letters have anatomy are not A.BC.D Similarities A C Not Similar B D (14) Look @ each image to decide which flow pattern is accurate. Look @ the image below. Look @ the image below. Look @ the image below. (15) Click on the image below and place a 1where the broadest groups of organisms are found and place a 2where the most specific organisms are found. 2 1 (16) We know organisms are classified based upon their structure. What other way can organisms be classified that is related to structure? by the habitats of where they came from by their biological ancestry by the person who discovered them by their reproductive parts (17) Layers 1, 2, 3, 4 in the image below are from undisturbed layers. Scientists found fossils of a particular bug in layers 1, 2, 3. What can be inferred about the species based on the fossils found only in layer 1? the species moved to a different part of the country The bug species went extinct because there was a change in the environment The bug species evolved into new species as time passed (18) Click here to view an image.The image showed the evolution of horses. What type of fossils should a scientist look to prove horses did evolved? They should look for fossils that are in the same layer They should look for fossils that have similar structures to that of the horse we see today They should look for fossils which look exactly like horses we see today. (19) When organisms die out and become extinct it is most likely due to multiple gene mutations lack of reproducing the changes in the environment (20) What causes scientists to think organisms may have evolved from a common ancestor? They were born in the same manner They have similar anatomies They have the same function (21) Click here to view an image. After viewing the image what conclusion about the structures can be drawn? They have the same function They have similar structures They are all extinct They use the same movement (22)If organisms are able to do things in more than one way, such as reproducing offspring, how would this be an advantage to organisms? It would allow the organism to be able to adapt to changing conditions It would allow the organism to be able to have more offspring It would allow organisms to become extinct (23) Click here to view an image.The image shows 4 different species of cells in a container. Some containers have all of the SAME type of cells and some containers have a variation of cells. Which container of cells will have the greater chance of survival? Container 1 Container 2 Container 3 Container 4
