SMART NOTES

Key ideas to know

Start with the relationships between ideas. Then close the notes and explain each one from memory.

  1. 01

    The Science section has 50 total questions, 44 scored questions, and 60 minutes.

  2. 02

    Eighteen scored items cover human anatomy and physiology.

  3. 03

    Nine scored items cover biology.

  4. 04

    Eight scored items cover chemistry.

  5. 05

    Nine scored items cover scientific reasoning.

  6. 06

    Homeostasis keeps regulated variables within workable ranges through feedback.

  7. 07

    Cell membranes regulate movement between intracellular and extracellular fluid.

  8. 08

    Chemical reactions conserve atom count and net charge.

  9. 09

    A controlled investigation alters an independent variable and measures a dependent variable.

Two ideas worth correcting now

NOT QUITE

Homeostasis keeps every variable perfectly constant

→
USE THIS INSTEAD

Regulated variables fluctuate within ranges.

NOT QUITE

A theory becomes a law after enough evidence

→
USE THIS INSTEAD

Laws describe patterns, while theories explain patterns.

The factor deliberately altered by the investigator.

8What is a dependent variable?Show answer ＋

The measured outcome.

PRACTICE QUESTIONS

Explain it in your own words

Use the answer as a check after you have written or spoken your response.

01Why does sweating cool the body?

Evaporation removes thermal energy from the skin.

02How can a cell placed in a hypotonic solution respond?

Water may enter by osmosis, causing the cell to swell.

03Why does a catalyst speed a reaction?

It provides a reaction route with lower activation energy.

04What does a control group provide?

A comparison for estimating the effect of the tested variable.

05Why does correlation not establish causation?

Direction may be unclear, and an unmeasured variable may influence both measured variables.
