DNA serves as the basic instruction manual for life. In this installment, we look at the way in which DNA is structured, replicated, and how it is packaged into such a small area. This will provide the basic understanding of how genes are structured in an easy to understand way.

Los insectos son el grupo más numeroso del reino animal. Información general sobre las abejas. La colmena: características, zánganos, abejas reina, obreras, funciones. Las abejas y el ecosistema.

In this book, some of the basic information and background into biology is broken down and explained. This serves as a quick and fast to the point introduction to biology. Some of the concepts explored include cell structure, taxonomy, biochemistry, and systems biology. With listening to this book, one could explain some of the simpler concepts of biology in a short time.

This serves as the second book in the Basics of Biology series. In this segment, the functions of membranes are explored. With regards to fully understanding biological organisms, the cell membrane is essential to developing an understanding of how cell function to control the substance that enter and exit them along with they way in which they interact with their environment.

Why do organisms grow old and die? What are the theories of aging? Does the Free Radical Theory of Aging still stack up? How do cells decide when to divide, differentiate or die? What factors accelerate the aging process? This essay takes a look at these issues and would thus be useful to students who want to know more about the processes that control cell death. The essay also documents the more extreme measures that some people have taken in the pursuit of eternal youth.

Thousands of people just like you have been raising bees and making their own honey right in their own backyards. Learn the ins and outs of the joy of keeping bees in this information packed beekeeping 101 guide.

The Western world has had an enduring love affair with dolphins since the early 1960s, with fanciful claims of their 'healing powers' and 'super intelligence'. Myths and pseudoscience abound on the subject. Justin Gregg weighs up the claims made about dolphin intelligence and separates scientific fact from fiction. He puts our knowledge about dolphin behavior and intelligence into perspective, with comparisons to scientific studies of other animals, especially the crow family and great apes.

We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: Why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others.

Did you know that the CIA once made use of a “spy cat”, or that, although delicious, eating the flesh of an armadillo can give you leprosy? And what about Terry, the small black Cairn Terrier from Kansas who was paid today’s equivalent of $2,000 a week for her work in The Wizard of Oz? Even if you think you have a handle on all things trivia, you're guaranteed a big surprise with Now I Know: Animals.

Did you know that San Diego’s Frozen Zoo is home to preserved DNA samples from over 8,000 endangered or threatened species, or that the tell-tale smell of freshly mowed grass is actually the plant’s version of a distress call? And what about Henrietta Lacks, the “immortal woman” whose cancer cells have been divided and multiplied for research purposes for over 60 years? Even if you think you have a handle on all things trivia, you're guaranteed a big surprise with Now I Know: Science.

In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets—and alien life—beyond our solar system. Only in the past two decades, after millennia of speculation, have astronomers begun to discover planets around other stars—thousands in fact. Now they are closer than ever to unraveling distant twins of the Earth. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration.

Our health care system is crippled by desperate efforts to prevent the inevitable. A third of the national Medicare budget - nearly $175 billion - is spent on the final year of life, and a third of that amount on the final month, often on expensive (and futile) treatments. Such efforts betray a fundamental flaw in how we think about healthcare: we squander resources on hopeless situations, instead of using them to actually improve health.

Outstanding field recordings of songs and calls of 60 species most common to the eastern U.S.: Warblers, Woodpeckers, Flycatchers, Thrushes, Larks, many more.

Noted ornithologist's outstanding field recordings of songs and calls. This set covers 60 birds with several recordings for each.

A classic work examining bird song as both a means of identification and study of behavior. This recording cites 72 species and 51 songs.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.

Barron's EZ-101 Study Keys give you a valuable overview of your college-level course. Classroom-style notes emphasize important facts, remind you what you need to remember for term papers and exams, and help guide you through the complexities of lectures and textbooks. Biology covers key topics, including the chemical basis of life, cells and tissues, bioenergetics, genetics, structure and function of body systems, ecology, evolution, and organic diversity.

We remember the admonition of our mothers: "Treat others as you want them to treat you." But what if being nice was something we were inclined by nature to do anyway? Renowned neuroscientist Donald Pfaff upends our entire understanding of ethics and social contracts with an intriguing proposition: the Golden Rule is hardwired into the human brain. Pfaff, the researcher who first discovered the connections between specific brain circuits and certain behaviors, contends that the basic ethics governing our everyday lives can be traced directly to brain circuitry.

As the snow melts and the spring approaches, the animal kingdom awakens. In Summer World, Bernd Heinrich, the best-selling author of Winter World, brings us an up-close and personal view of that awakening and rebirth.

It has been remarked that if the brain were so simple we could understand it, we would be so simple we couldn’t. Commencing with a brief history of neuroscience, from the ancient practice of drilling holes in the head to relieve headaches to the latest results from MRI and CT scans, this accessible guide sets out to explore exactly what we do know about the brain. Including the most up-to-date research on the cerebral processes, this entertaining introduction assumes no previous scientific knowledge.
