2What is a fossil? Vocabulary 100 The remains of organisms preserved in the earth.What is a fossil?
3What is a vestigial organ? Vocabulary200A reduced and unused physical structure in an organism, which was more developed in an earlier group of organisms.What is a vestigial organ?
4What is speciation? Vocabulary 300 A population of a species becomes physically separated into two populations for a period of time. Later these populations come together and are not able to breed. This is an example of__________.What is speciation?
5What is natural selection? Vocabulary400This caused the forelimb adaptations represented by structures B, C, and D.What is natural selection?
6What is a gene? Vocabulary 500 A segment or section of DNA that relates to a specific trait or function of an organism.What is a gene?
7Earth –A Home for Life100The correct order that mammals, insects and reptiles appeared on land.What is insects, reptiles, and mammals?
8Earth –A Home for Life200The first multicellular organisms to live on land appeared this many years ago.500 million B. 3.8 billion1.2 million D. 1.2 billionWhat is A – 500 million.
9Earth –A Home for Life300During the Permian Extinction, about _______ of the species living in the ocean became extinct.90% C. 50%10% D. 1%What is A. 90%?
10Earth –A Home for Life400Scientists think that this is what caused the Permian extinction 250 million years ago and how and why it may have happened.What is what is the Earth’s land masses joining together causing 90% of the species in the ocean and many land dwelling animals to die ? The formation of one big continent changed the climate and conditions in the ocean.
11Earth –A Home for Life500This is when, why and how scientists think the Cretaceous extinction happened and what disappeared.What is 65 million years ago scientists think that an asteroid hit the Earth which caused a climate change and the dinosaurs disappeared? After the dinosaurs died out, many new mammals began appearing.
12Species Change over Time 100 The relative age of a fossil tells you a. whether one fossil is older or younger than another fossilb. exactly when a fossil was formedc. the amount of radioactivity in a fossild. how long the fossilized organism was alive on EarthWhat is A, whether one fossil is older or younger than another fossil?
13Species Change over Time 200 Lamarck proposed that species evolve because:they adapt to their surroundings over time.they can pass on traits acquired during their lifetimes to their offspring.they overproduce and a variety of species come from each offspring.natural laws decide when they should change.What is B, they can pass on traits acquired during their lifetimes to their offspring?
14Species Change over Time 300 Most__________ will become more common from one generation to the next.variationsmutationsspeciationsadaptationsWhat is c speciations?
15Species Change over Time 400 According to Lamarck, could the parents of the tortoise from Abingdon Island be born with a short neck?What is yes, they could have stretched their necks during their lives and then passed on that trait to their offspring?
16Species Change over Time 500This is how variation and adaptation may have led to the development of long-necked tortoises on Abingdon Island.
17Species Change over Time 500 Answer Slide The offspring of the ancestors of present-day tortoises on Abingdon island differed from each other in small ways.One of these variations was likely neck length. The tortoises competed with one another for leaves.The better adapted tortoises, with long necks, survived and reproduced at a higher rate.Therefore, long-necked tortoises became more widespread.
18Evidence for Evolution 100 A lizard and a bat have similar forelimbs, but they are used in different ways. This is evidence that supports the theory of evolution by_________.artificial selectionnatural selectionacquired characteristicssimilarity of structuresWhat is similarity of structures?
19Evidence for Evolution 200One of the following pairs of organisms will have the most similar genes.tree and flowerflower and bacteriumbacterium and humanhuman and treeWhat is a, tree and flower?
20Evidence for Evolution 300This is why structure A in the diagram to the right is an example of a vestigial organ.What is the whale leg is a structure that was fully developed in whale ancestors; now it has become reduced and unused in modern whales?
21Evidence for Evolution 400Structures B, C, and D are forearms of different animals share a common ancestor. What type of biological evidence is this?What is similar structures with different functions?
22Evidence for Evolution 500Four types of evidence that scientists use to support the theory of evolution.What are by observation, fossil evidence, biological evidence, and genetic evidence?
23Random facts.100The name of Tim’s robot.What is Moby?
24Random Facts200What Precambrian time refers to.What is the earliest period in Earth's history?
25Random Facts300What you should do to the caps on plastic bottles.What is take them off before recycling?
26Random Facts400These are four renewable resources.What is sunlight, wind, water, trees and other plants, and animal waste?
27Random Facts500The name of the ship that Darwin travelled to the Galapagos Islands on.What is the Beagle?
28What is 100 cm? Metric system 100 The number of centimeters in one meter.What is 100 cm?
29Metric system200Centimeters in one kilometer.What is 100,000 cm?
30Metric system300Millimeters in one meter.How much is 1,000 mm?
31Metric system400The number of meters to measure out 365 years where 1cm = 1 year.What is 3.65 m?
32What is 350 cm? Metric system 500 The number of centimeters in three and a half meters.What is 350 cm?
33Final JeopardyThe bones of a whale flipper (left) are similar to the bones of a bat wing (right) as shown in the illustration below. What does this similarity in bone structure suggest about the whale and the bat?They use the same methods to travel.They can migrate to the same locations.They evolved from a common ancestor.They can manipulate objects in the same way.
34Final Jeopardy Answer: What is C. They evolved from a common ancestor?
