A conclusion drawn from a general principle is a(n) deduction.

(a)  

A conclusion drawn from specific observations is a(n) induction.

(a)  

An observation that isn’t easily measured is called a(n) qualitative observation.

An observation that is measurable is called a(n) quantitative observation.

A tentative explanation based on previous knowledge is called a hypothesis.

(a)  

A hypothesis must be testable.

An experiment is a test of the hypothesis.

Define variable.

How many variables are tested in an experiment?

(a)  

What should you attempt to do with any other variables present in your experiment?

Which variable is located in the experiment & is the one that the investigator is deliberately changing?

Which variable is located in the results & is the response that the investigator measures?

What are the conditions or variables called that will remain the same during your experiment?

(a)  

What term represents something located in the control group that is similar to the independent variable but has no effect?

(a)  

What is the best example of a true control?

(a)  

Define placebo.

The number of individuals participating in an experiment is called the sample size.

The higher the number of individuals participating in the experiment the more meaningful the results.

A conclusion accepts or rejects the hypothesis. A rejected hypothesis is called a null hypothesis.

A theory is a comprehensive, unifying explanation & is what is most widely accepted. List 1 example of a theory.

(a)  

Bio- means life and –ology means study of. So, biology is the study of life.

All life is composed of cells.

Define cell.

An organism composed of 1 cell is unicellular and an organism composed of more than one cell is multicellular.

Define metabolism.

Define cellular respiration.

Metabolism creates body temperature.

An organism that has a higher body temperature is called a(n) endotherm.

(a)  

An organism that has a lower body temperature is called a(n) ectotherm.

(a)  

Ectotherms have slow metabolisms and need heat from the outside to maintain a higher body temperature.

Endotherms have fast metabolisms and generate their own heat.

List an example of a type of animal that is classified as an ectotherm.

List an example of a type of animal that is classified as an endotherm.

(a)  

Endothermic animals eat MORE often than ectothermic animals.

Define homeostasis.

Homeostatic mechanisms are self-regulating. What does this mean?

If a human’s urine is dark yellow, what might that indicate?

(a)  

How would the body react to fix the above situation?

The production of new offspring is called reproduction.

Define heredity.

Heredity occurs through the passing of traits using genes.

Life evolves or species adapt to their environment through time.

Life is highly organized & placed into a hierarchy.

New or novel properties that emerge as you move up the organizational hierarchy are called emergent properties.

List 1 example of emergent properties.

(a)  

Levels of organization (smallest to largest): subatomic particle → atom → molecule → macromolecule → organelle → cell → tissue → organ → organ system → organism → population → species → community → ecosystem → biome → biosphere

The smallest unit of matter is a(n) subatomic particle.

Two or more atoms bonded together is a(n) molecule.

(a)  

Large organic molecules like proteins, carbohydrates, lipids, & nucleic acids are macromolecules.

Small structures inside cells with specific functions are called organelles.

The smallest unit of life is the cell.
