In the 19th century, a monk named Gregor Mendel studied how different types of pea plants passed their characteristics to the next generation. His studies in heredity led to science's current understanding of genetic inheritance and how traits are passed down from parents to children. In ""Heredity"", travel through the history of genetics from the early ideas of heredity to Watson and Crick's discovery of the structure of DNA to the future of genetic research. Through these discoveries, scientists can now decipher the 'code of life', see how cells divide, and study how certain traits are passed from parent to child. Experiments with heredity have also created promising results for tests for genetic disorders, the Human Genome Project, cloning, and future cures for many common diseases like heart disease and cancer.

Fireworks light up the summer night sky with their colorful displays, forensic experts use DNA to help solve crimes, and deep-sea creatures illuminate the depths of the ocean in search of their next meal. All these things happen because of chemical reactions, but what exactly is a chemical reaction? Filled with intriguing full-color photographs, insightful sidebars, and other essential features, this insightful new book helps students fully understand how chemical reactions happen - covering atomic structure, chemical bonding, reaction rates, and more.

Since cells are the smallest of all living organisms, scientists have had to develop various methods and tools to examine and research them. In the 17th century, the microscope was invented, allowing researchers a glimpse at the cell. Today, supercomputers put cells and experiments to the test. In microbiology laboratories and cancer research centers, well-trained, dedicated scientists work to explore the science of cells, making biotechnology a continuously growing field. In How Scientists Research Cells, learn how the first discovery of cells led to the first cloned mammal and additional scientific advancements.
