Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

Identify the new traits that first appear in seedless tracheophytes
Discuss how each trait is important for adaptation to life on land
Identify the classes of seedless tracheophytes
Describe the life cycle of a fern

Describe the structure of the root
List and describe examples of modified roots

Students extend their understanding of properties of exponents to include rational exponents and radicals, and investigate rates of change in linear and exponential sequences and functions.

Learn Alberta offers a real-world scenario of skateboarding to introduce the concept of square roots. This multimedia site offers two videos, printable exercises and interactive exercises of finding the square root through visual prompts of squares.

A thorough description of chords, roots, and triads. Provides illustrated examples as well as audio clips to supplement this lesson.(You may need to download Flash Player to view this site.)

This is an index of links to activities using root words. These activities are separated into 3 levels of difficulty. These interactive, vocabulary puzzles and activities use Latin and Greek "roots and cells" to help unlock word meanings. There are eight exercises in each lesson and they include various word puzzles such as crosswords, wordsearch, and fill-ins. Java is required.

What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of transpiration, or the release of moisture to the atmosphere by plants.

Students gain an understanding of the parts of a plant, plant types and how they produce their own food from sunlight through photosynthesis. They also learn about transpiration, the process by which plants release moisture to the atmosphere. With this understanding, students test the effects of photosynthesis and transpiration by growing a plant from seed. They learn how plants play an important part in maintaining a balanced environment in which the living organisms of the Earth survive. This lesson is part of a series of six lessons in which students use their evolving understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Polynomial functions are functions with x as an input variable made up of several terms, each made up of two factors. Click the links for detailed explanations and examples.
