The Brain—Information about the Brain. 1 Introduction “I think, therefore I am.” —René Descartes, 17th-century philosopher Few of us question the crucial importance of the brain. It is vital to our existence. Our brains enable us to think, as René Descartes so skillfully pointed out nearly 400 years ago. Yet the human brain is responsible for so much more. The brain makes up only 2 percent of our body weight, but it consumes 20 percent of the oxygen we breathe and 20 percent of the energy we consume. Scientists have worked for many years to unravel the complex workings of the brain.
Despite these and other significant advances in the field of brain research, most of the processes responsible for the integrated functioning of billions of brain cells remain a mystery. An essential aspect of any scientific research is communicating results to the public in a way that is easily understood. 2 Myths and Realities about the Brain Myth: The brain is separate from the nervous system.
Myth: The brain is a uniform mass of tissue. 4.2 Glia. Dichotomous key classification. Plant Identification Game Using an Online Interactive Dichotomous Key Introduction: By looking at characteristics of a plant or animal and using a dichotomous key, you can identify most living things to the species. In this situation the term "dichotomous" means to divide into two groups that are not alike and most dichotomous keys work by using the individuals characteristics to place the organism into smaller and smaller groups until it can be identified to the species.
Dichotomous keys usually include only certain groups of organisms, like trees or butterflies. The usefulness of a key is only as good as the author's purpose. Some keys are intended to cover only the most common species, while others are very comprehensive and require extensive knowledge of biology or botany. This game is intended to introduce you to how a dichotomous key is used. How to play: To begin, choose one of the plant buttons below to open a photo in a new window. The organism is red The organism is not red. Map of the Human Heart. Map of the Human Heart Day and night, the muscles of your heart contract and relax to pump blood throughout your body. In the Step Thru below, see the complicated path the blood takes as it moves in and out of the heart. Step Thru Animation Oxygen-poor blood (shown in blue) flows from the body into the right atrium. Blood flows through the right atrium into the right ventricle. The right ventricle pumps the blood to the lungs, where the blood releases waste gases and picks up oxygen.

Hold out your hand and make a fist. Give a tennis ball a good, hard squeeze. The aorta, the largest artery in the body, is almost the diameter of a garden hose. Feel your pulse by placing two fingers at pulse points on your neck or wrists. Lub-DUB, lub-DUB, lub-DUB. Genes and Appearance. In this activity, you will change the way a dragon looks by changing its genes.
Introduction How do genes determine appearance? As we all know, dragons are fictional animals, but they work well for learning genetics. Dragons have very few heritable traits, and most of those traits are controlled by single genes with a simple dominant-recessive pattern of inheritance. This makes dragons a great organism in which to study genetics. Dragons do have one example of incomplete dominance; their legs come in three varieties. Observe the dragons above (green, yellow, and purple) and describe the three leg varieties that result from incomplete dominance. Standards NSES Life Science – Reproduction and Heredity Every organism requires a set of instructions for specifying its traits. NSES Life Science – Reproduction and Heredity Hereditary information is contained in genes, located in the chromosomes of each cell.
