Animal Form and Function Animal bodies come in a variety of sizes and shapes. Limits on animal size and shape include impacts to their movement. Diffusion affects their size and development. Bioenergetics describes how animals use and obtain energy in…
LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses Animals must be able to maintain homeostasis—the ability to maintain dynamic equilibrium around a set point—while also being able to respond to changing conditions. For example,…
LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses The content described in this section is not within the scope of AP®. However, we have already learned that the relationship between structure and function includes…
LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses As you have learned, specialized cells in the animal body are organized into tissues, organs, and organ systems, which efficiently localize functions, such as the digestion…
Figure 24.1 An arctic fox is a complex animal, well adapted to its environment. It changes coat color with the seasons, and has longer fur in winter to trap heat. (credit: modification of work by Keith Morehouse, USFWS) Chapter Outline 24.1 Animal Form…
Prokaryotic Diversity Prokaryotes existed for billions of years before plants and animals appeared. Hot springs and hydrothermal vents may have been the environments in which life began. Microbial mats are thought to represent the earliest forms of life on Earth,…
