hypothesize that a drug called "shrinkase" will inhibit the growth of a particular type of
cancerous tumor. What is my next step in the scientific process? - correct answer ✔✔Determine

correct answer ✔✔anecdotal
You have the following known facts: smoking causes accumulation of materials in the lungs,
thereby decreasing oxygen-absorbing capability of the lungs. Long-term smoking causes more
,accumulation of materials in the lungs. Decreased lung capacity increases the workload of the
heart. Which of the following hypotheses can you make from these observations? - correct
answer ✔✔Long-term smokers have poorer heart health than non-smokers
In a controlled experiment, the control and experimental groups differ in the - correct answer
✔✔independent variable
A placebo is given to the: - correct answer ✔✔control group
What is the importance of a placebo? - correct answer ✔✔It allows the researcher to treat
control and experimental groups differently while allowing them to believe they are being
treated the same.
What a the difference between a hypothesis and a theory? - correct answer ✔✔A hypothesis is
an assumption made before any research or testing, while a theory is an explanation already
supported by data.
