What is the primary reason scientists classify living organisms?
To make them look pretty in textbooks
To decide which organisms are more important than others
To organize the diversity of life and study relationships
To give them long, complicated names
Which of the following is the most general (broadest) classification group?
Family
Class
Order
Kingdom
What are the two parts of a scientific name using binomial nomenclature?
Family and Order
Genus and Species
Class and Genus
Kingdom and Phylum
Which of these levels of classification comes immediately after 'Class' in the hierarchy?

Phylum
Why is it important to use scientific names (like Homo sapiens) instead of common names (like human)?
Common names are too short and confusing.
Only scientists are allowed to use scientific names.
Scientific names are universal and avoid confusion caused by different common names in different languages/regions.
Scientific names are always in English, making them easier to understand.
Which of these is a characteristic of all living things?
They can fly.
They have complex brains.
They are made of one or more cells.
They produce their own food.
The scientific name for a wolf is Canis lupus. What does 'Canis' represent?
The species
The family
The kingdom
The genus
If two organisms belong to the same Family, they must also belong to the same...
Genus
Order
Kingdom
Species
Why is classification important in biology?
It helps identify evolutionary relationships between different species.
It makes it easier to assign organisms to different habitats.
It allows scientists to predict characteristics of newly discovered organisms.
It helps scientists organize and understand the vast diversity of life.
Which characteristics are shared by all living organisms?
Responds to stimuli
Ability to photosynthesize
Ability to reproduce
Composed of cells
A student observes a newly discovered organism. Which of the following features would indicate it is a living thing?
