Thirty-five newly hatched L1 were cultured at specific pH medium. The earliest observed egg laying time on each plate was recorded. Error bars represent the standard error from three replicated experiments.
a. . Below are two teleological statements. Rephrase them so that they do not imply a goal or purpose and are therefore are scientific. i. Birds have wings so they can fly. ii. Ducks have developed webbed feet to swim more efficiently. b. Why are teleological statements unscientific?
You will eventually set up an experiment in which you test the effect of household cleaners on bacterial reproduction. Review your scientific method steps and answer the following questions: a. Identity your independent and dependent variables b. What might you do as the "objective observation" steps of your experiment? Recall that "objective observation" is the very first step of scientific method and precedes hypothesis formation.
The inductive method does not require a.Large numbers of observations b.careful observations c.an hypothesis d.repeated observations
The doctor set up a diagnostic test for George in which he received a low dosage of radioactive iodine compounds. The results of the levels of radioactive iodine in his blood were then compared to the levels of radioactive iodine in the blood of a healthy human. The results are shown in the graph below. 100 George 80 60 40 healthy human 20 3 Time After Admnistration of Radioactive lodine (days) 3. a. Write the hypothesis the doctor was investigating with this test. Answer: b. What was the purpose of giving a healthy human radioactive iodine compounds in this experiment? Answer: C. Do the results shown in the graph support the hypothesis? Explain your answer. Answer: Suggest why the graph for the healthy human rose after approximately two days. Answer: е. Outline one treatment that might enable George to recover. Answer: Percentage of Original Radioactive iodine in Blood (%)

An adequate sample size controls for chance events and individual variationsin response and thus enables us to place more confidence in the outcome. For example, would you rather trust your health to a drug that was tested on 5 people or one tested on 5,000? Why?
Inductive reasoning begins with a theory -- is true or false? Research studies should never have assumptions, as these should havve been controlled for -- is true or false?
Consider that you are a civilian resident living on the Chatham Island in New Zealand where a long-finned pilot whale stranding event with 100 beached whales is happening and maybe have even been participating in the response to the strandings. Raise specific questions that you may have for the local government or researchers about the stranding. Argue for an alternate hypothesis as to why the event occurred. Use and fully cite in-text peer-reviewed journals and government organizations, to support all data. Then, provide a full reference section at the end to list all the sources used
An experimenter tests the effectiveness of 2 diets on goldfish growth. Ten goldfish in aquarium 1 are fed diet A, while 10 different goldfish in aquarium 2 are fed diet B. The fish are all approximately the same size at the start of the experiment, and the average weight of the goldfish are measured after 2 months of feeding with the 2 diets. This kind of experiment would be best labelled as a: O Comparative experiment O Natural experiment O Manipulative experiment estion 20 perimenter tests the effectiven rium 1 are fed diet ( are all an
