Read the sample student claim and the reasons listed for making this claim.
Which piece of evidence would best support reason #1?
Claim: Although many people argue that medical testing
on animals is a violation of animal rights, the benefits it
yields for society far outweigh any argument that can be
made.
O The history of using animals for research extends as
far back as 322 BCE, when early Greek physician-
scientists, such as Aristotle and Erasistratus,
performed various experiments on living animals.
O Animal research played an essential role in the
development of Herceptin and Tamoxifen, two
medications that have already saved the lives of
thousands of women who have been diagnosed with
breast cancer.
Reason #1: Animal research has yielded both pain-
relieving and life-saving drugs for humans.
Reason #2: Laws prohibit scientists from using animal-
based research in cases where non-animal testing
would produce equally clear and valid results.
O Even those who believe in testing on animals when it
is necessary for vital medical research practice what
is known as "the 3 Rs"-reduction, refinement, and
replacement—to reduce the number of animals used
for testing.
O Biologists believe that chimpanzees share at least
98.4 percent of the same DNA as humans and
gorillas share at least 97 percent, making primates a popular and like choice for the testing of products intended for humans

Need asap which of these is an example of a hypothesis? (2 points) a. adults were not interviewed b. the investigation was time consuming c. the source of information was biased d. very few teenagers were interviewed scientists in different parts of the world have conducted experiments to find the speed of light in vacuum. if the results of the experiments are identical, they would most likely be (2 points) a.valid b. biased c. unreliable d. non-observable which of these questions can be answered using science? (2 points) a. what is the best career? b. does water exist on venus? c. should the use of automobiles be stopped? d. which is the most interesting subject to study? the models can be best used to (2 points) recreate something which is easily observed in nature prove that all atomic theories have the same meaning demonstrate the transformation of atomic theory into law represent the locations of subatomic particles in different atomic theories 22. (bws.06) scientists earlier believed that the lowest measurable temperature is the freezing point of ice. however, modern scientists believe that temperatures below the freezing point of ice can also exist. what best accounts for these different opinions? (2 points) scientists propose contradictory ideas to include all possibilities scientists come up with different hypotheses without enough evidence scientists propose different ideas to avoid repetition of scientific knowledge scientists having different interests may interpret the same data in different ways based on the graph, what is the most likely mass of an apple chosen randomly from the basket? (2 points) between 0.10 kg and 0.12 kg between 0.12 kg and 0.14 kg between 0.14 kg and 0.16 kg between 0.16 kg and 0.18 kg a scientist studies a model of a widely accepted theory about the position of planets and sun. the model would most likely the scientist to (2 points) prove that the theory would not change in the future demonstrate how the theory can be changed into a law understand facts which cannot be easily observed prove that all other facts about the universe are incorrect one scientist discovered a new theory on the evolution of the universe. what is the next step for the scientist to take? (2 points) transform the results of the theory into universal laws of nature inform the scientific community so they can verify the results call a press conference to make the discovery popular among people encourage scientists worldwide to find an appropriate application for the results the students' observations are listed below. when an iron nail is taken near the north pole (n) of the bar magnet, it is pulled towards the magnet. when an iron nail is taken near the south pole (s) of the bar magnet, it is pulled towards the magnet. the experiment was repeated by several students using different bar magnets. based on the investigations, which of these theories would the students most likely propose? (2 points) magnets attract iron nails the poles of a magnet attract all materials iron nails are attracted towards all materials iron nails have the same properties as magnets
