Term 1 test 1 Flashcards
What are the characteristic layers of the ocean?
The ocean consists of distinct layers that impact various abiotic features.
How do the ocean layers affect abiotic features?
They influence density, pressure, light penetration, temperature, and oxygen concentration.
What is the process of classification?
Classification is the grouping of things according to their degree of similarity.
What does the term hierarchical mean?
Hierarchical refers to a system organized by levels of rank or importance.
How can anatomical features be used in classification?
Anatomical features can be observed and used to classify organisms.
Why is classification important in science?
It is essential for effective scientific communication.
What can be identified between organisms?
Similarities and differences can be identified.
What is a dichotomous key?
A tool used to identify organisms based on observable characteristics.
How can observable characteristics be used in classification?
They can classify organisms into different hierarchical levels using dichotomous keys.
What is the difference between invertebrates and vertebrates?
