Question 1

In Hawaii State Assessment, what is the purpose of the scientific method in science?

Accepted Answer

To provide a systematic approach for investigating questions and testing hypotheses

Answer

The scientific method provides a structured, systematic approach for asking questions, forming hypotheses, designing experiments, collecting data, and drawing evidence-based conclusions.

Question 2

What is a controlled variable in an experiment related to Hawaii State Assessment?

Accepted Answer

A factor that is kept constant throughout the experiment

Answer

Controlled variables (constants) are factors that are deliberately kept the same throughout an experiment to ensure that any observed changes are due to the independent variable being tested.

Question 3

Which level of biological organization represents the most complex in Hawaii State Assessment science?

Accepted Answer

Ecosystem

Answer

The hierarchy from simplest to most complex goes: atom → molecule → cell → tissue → organ → organ system → organism → population → community → ecosystem → biosphere.

Question 4

In Hawaii State Assessment, what is homeostasis?

Accepted Answer

The body's ability to maintain a stable internal environment despite external changes

Answer

Homeostasis is the process by which biological systems maintain internal stability and balance (temperature, pH, glucose levels, etc.) while adjusting to changing external conditions.

Question 5

What is the primary function of the mitochondria in cells relevant to Hawaii State Assessment?

Accepted Answer

To produce energy (ATP) through cellular respiration

Answer

Mitochondria are the "powerhouses" of the cell, converting nutrients into ATP (adenosine triphosphate) through cellular respiration, providing the energy needed for cellular functions.
