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.

By the end of this section, you will be able to do the following:

Define “energy”
Explain the difference between kinetic and potential energy
Discuss the concepts of free energy and activation energy
Describe endergonic and exergonic reactions

Biology, The Cell is an unit of study no. 3 of the Biology full course. It is grounded on studying cells, including cell structure, structure and function of plasma membranes, metabolism, cellular respiration, photosynthesis, cell communication, and cell reproduction.

Diagnostic studies and discussion of their implications for the theory of the structure and general circulation of the Earth's atmosphere. Includes some discussion of the validation and use of general circulation models as atmospheric analogs.

Physics is a study of Energy and its transformations. One of the ways of energy transformation happens when objects are set in motion. Description of motion has been studied in Mechanics I module. The emphasis on mechanics I was on the kinematic and dynamic description of particles motion.

This module extends the kinematics and dynamics of particle motion to dynamics of a system of particles; rotational motion rigid bodies and Gravitation. Hence ability solve problems using the equation of motion of a rotating rigid body when the motion is about any fixed axis, as well as when the motion is about a principal axis will be developed. Furthermore the learner will be able to calculate the kinetic energy of rotation of a rotating rigid body and use this as an additional form of kinetic energy in solving problems using the conservation of energy.
