life (biology)

Readers will develop an understanding of living, non-living, and things that used to be alive.

An introduction to animals cells, covering where they are found, different types, how they are studied, and more. Includes audio, videos, activities, weblinks, slideshows, transparencies, maps, quizzes, and supplementary resources.

Highlights the pioneering scientists who set out to understand such simple complexities as how our bodies produce the right number of cells and how nature produces the right number of creatures to balance an ecosystem. Explores the scientific revelation that everything on earth, from our cells to every wild plant and animal, is regulated by rules that are remarkably similar and cohesive in the common underlying logic of life. Includes charts, maps, and photographs.

It is time to learn about living things.

"Foxes, rabbits, mongooses, rats, starlings, turtles, Burmese pythons, and Asian carp are just a few of the invasive animals introduced by people into countries and ecosystems to which they do not belong. This important book describes how these animals are destroying habitats and endangering the lives of native animals, some of which have been brought close to extinction. Students will learn how some arrived accidentally on boats, while others were brought in by people, to be used either as a form of pest control on farms, for hunting or hobbies, or as pets that sometimes get abandoned in the wild by owners. Many native animals, such as raccoons, squirrels, and coyotes have also become invaders in cities, back yards, and homes. Students can research invasive species in their areas and help find ways to stop these wild invaders from taking over the natural habitat."--Provided by publisher.

"Simple text and colorful photos introduce readers to the difference between living and nonliving things"--.

Atoms are the basis of every living and non-living thing on Earth, but where and how did life begin - and how do we know?.

Presents several reference tools, including an evolutionary tree, a glossary, a further reading list, a list of resources for younger readers, annotated lists of Web sites and places to visit, and six indexes.
