Chapter: Evolution, Evidence & Life HistoryWhat these drills covers
By the end of Life Science Capstone: Explain, Test & Revise you should be able to:
- I can explain life science capstone: explain, test & revise.
- I can use evidence, a model, and stated assumptions to support a biological explanation.
4 questions, multiple choice, numeric and written answer, each with a worked explanation.
Vocabulary used: inquiry report, assumption, alternative explanation, qualification, revision.
Problem 1
Which improves an inquiry conclusion?
- State its evidence and limitation
- Omit every assumption
- Call one graph universal proof
- Copy a model without reading the record
Answer and explanation
State its evidence and limitation
A clear evidence connection and qualification make the conclusion assessable.
Problem 2
A variant share rises from 25% to 40%. Find the increase in percentage points.
Answer and explanation
15 percentage points
40−25=15 percentage points; a relative percent increase is a different calculation.
Problem 3
Why define the population and interval?
Answer and explanation
They determine what the measured change concerns and prevent a local record from becoming a universal claim.
Problem 4
How should an assumed inheritance rule be reported?
Answer and explanation
State it as a supplied model assumption and distinguish it from measured offspring evidence.
