Scientific Investigation questions are answered primarily from:

The method (the experimental design)

Keeping every test tube at the same temperature in an experiment is intended to:

Control temperature so it does not confound the results

Lowered blood pressure in the adults aged 40 to 60 who were studied

Partly consistent: it supports the hypothesis up to medium light but not beyond

The answer is not provided in any figure or sentence

An upward-curving line whose slope increases

A downward curve that levels off (steep at first, flatter later)

Test additional temperatures between and beyond those already used

They move together, but this alone does not prove causation

Which reporting category is the largest on ACT Science?
A population is 100 at 0 h, 400 at 2 h, and 1600 at 4 h. The trend is best described as:
Scientific Investigation questions are answered primarily from:
Keeping every test tube at the same temperature in an experiment is intended to:
A study found a drug lowered blood pressure in adults aged 40 to 60. The best-supported conclusion is that the drug:
A hypothesis predicts taller growth with more light. Growth rose from low to medium light but fell at high light. This result is:
You recognise an outside-knowledge question on ACT Science when:
A passage lists water samples with pH 3, 6, 7, and 9 but never defines pH. The most acidic sample has pH:
A table shows distance of 0, 5, 20, 45 m at 0, 1, 2, 3 s. The matching graph is:
A passage says volume 'decreased, falling more slowly at higher pressures.' The matching graph is:
To better define how a reaction rate changes with temperature, researchers should:
A study shows two variables are strongly correlated. The safest conclusion is that:
