Though it encompasses the majority of the Earths history, much about Precambrian time still remains unknown to us. With its climate extremes and unstable surfaces, Precambrian Earth hardly resembled the planet we see today. Yet for all its differences, it made the existence of future generations possible. This volume helps unlock the mysteries of prehistory by considering available geologic evidence while providing a deep dive into the finesses of geochronology.

Despite the vast diversity of living organisms on Earth, all life falls into only one of two categories: prokaryotes or eukaryotes. Examining the basic parts of a cell, cell types, cell function, and cell reproduction, this concise volume explains what makes certain cells eukaryotic and others prokaryotic and how the two cell types are related. Detailed diagrams complement the text to help readers easily identify various cell features and integrate textual and visual information, in line with Common Core requirements.

The interconnectedness of the ear, nose, and throat is evident when you consider how the smell of garlic cloves on the grill or chocolate chip cookies in the oven can affect your perception of their taste, or how a runny nose and scratchy throat can lead to an ear infection. In addition to enabling sensory perception, the ear, nose, and throat perform a number of vital functions in the human body. This incisive volume examines the structure of each in turn and in concert with the other, also exploring the diseases and disorders that sometimes afflict them.

Readers learn that a living organism is a system, or structure, that reproduces, changes with its environment over a period of time, and maintains its individuality by continuous metabolism. To maintain life, an organism repairs or replaces (or both) its structures by a constant supply of the materials of which it is formed. It keeps its life processes in operation by a steady supply of energy. A major contributing part of an organism's survival is the functioning of its cells. This volume provides essential information on cell functions, including amino acids, fibrous and globular proteins, DNA, protein synthesis, and metabolism.

Audio and visual cues facilitate some of our most powerful sensory experiences and embed themselves deeply into our memories and subconscious. Sound and light waves interact with our ears and eyesour biological interpreterscreating a textural experience and relationship with the world around us. This well-researched volume explores the science behind acoustics and optics and the broad application they have to everything from listening to music and watching television to ultrasonic and laser technologies that are crucial to the medical field.

Millions of people are calorie-conscious. They measure the number of estimated calories contained in their meals primarily because they wish to lose weight or avoid gaining it. But many of these people miss the big picture, the fact that regular exercise is as important as caloric discipline. This book explains the ins and outs of calories for young children. It describes the sources of calories, daily calorie needs, the meaning of empty calories, and the problems that can result if someone eats too many of them. Your readers will understand the need to balance caloric intake with exercise.

Formalizing study of the natural world may seem like a daunting task considering the sheer breadth and variety of living things that inhabit the planet. From the microscopic organisms in the worlds most remote locations to those in the human body, evidence of the intricate structures and mechanisms that enable life are ubiquitous and new discoveries constantly reveal new possibilities that demand to be examined. This volume surveys the multitude of subjects that comprise the field of biology and includes an overview of the development of biology, microbiology, and cell theory.

Even as airlines provide faster means of travel, ships and boats remain as important as ever in transporting passengers and cargo across the world’s bodies of water. While ship design has become increasingly sophisticated with time, everything including the luxury liners, warships, and sailboats of today owe much to the watercraft that facilitated travel, trade, and war among ancient cultures. This detailed volume examines the development of the different types of water vehicles and the design of related structures, including docks and quays.

Constituting more than 70 percent of Earths surface, the worlds oceans are so vast as to remain something of an enigma to this day. Navigating these imposing seas and unlocking their secrets is the calling of oceanographers. Their research helps determine what climatic, geologic, and chemical impact oceans have on a variety of organisms. In spite of their magnitude and might, the worlds oceans are not immune to the effects of adverse human activity, such as pollution. This volume surveys this huge, but fragile, ecosystem and the individuals who help fight for the preservation of this vital resource that has critical significance to all earthly life.

Celebrated for numerous developments in the areas of law, writing, religion, and mathematics, Mesopotamia has been immortalized as the cradle of civilization. Its fabled cities, including Babylon and Nineveh, spawned new cultures, traditions, and innovations in art and architecture, some of which can still be seen in present-day Iraq, Iran, Syria, and Turkey. Readers will be captivated by this ancient cultures rich history and breadth of accomplishment, as they marvel at images of the magnificent temples and artifacts left behind.
