Water Cycle: The water cycle describes the existence and movement of water on, in, and above the Earth. Earth's water is always in movement and is always changing states, from liquid to vapor to ice and back again. The water cycle has been working for billions of years and all life on Earth depends on it continuing to work; the Earth would be a pretty stale place without it. The water cycle has no starting point. But once the water is evaporated from its source (seas, oceans, ponds, lakes, etc.), it is taken to the atmosphere by vapor current. When the vapor is in the atmosphere the water condenses into the cloud and it falls back to the earth in the form of cloud particles. This is known as precipitation. Nitrogen Cycle:

Plants derive most of their organic mass from the CO2 of air ? also depend on soil nutrients such as water and minerals ? classic experiments by Jean-Baptiste van Helmont & Stephen Hales ? nitrogen acquired mainly as nitrate ions (NO3?) Copyright ? 2005 Pearson Education, Inc. publishing as Benjamin Cummings Essential Elements ? more than 50 chemical elements found in inorganic substances in plants ? not all of these are essential ? chemical element is considered essential if it is required for a plant to complete a life cycle

Campbell's Biology, 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5, the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers, and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure, because this is central to understanding subsequent chapters on metabolism, molecular biology, and molecular medicine. Multiple-Choice Questions 1) Humans and mice differ because A) their cells have different small organic molecules. B) their cells make different types of large biological molecules.

AP Biology Guided Reading Chapter 41 1. Contrast the terms undernourished, overnourished and malnourished? Undernourished is when an animal does not have enough nutrients and therefore does not have enough energy, while overnourished is when the animal have too much nutrients, which will be stored as fat. Malnourished is when an animal does not have enough of one or more essential nutrients. A person can be overnourished, but still be malnourished if they are lacking one or more essential nutrients. ? 2. What are essential amino acids and essential fatty acids? Essential amino acids and fatty acids are ones that the organism cannot make and therefore must obtain in their diet. ? 3. Contrast vitamins and minerals.

Excretory System Read Kraus pages 248 to 250. List the many different?functions of the skin: There are four different functions for the skin. The skin acts as a protective organ, meaning that the skin provides defense from mechanical injury and bacterial infections. How does the liver assist with excretion of nitrogenous?waste? The liver assists with the excretion of nitrogen waste. When humans eat food containing a surplus in protein, an excess of amino acid forms. Amino acid contains nitrogen. If the protein is not used to repair the body or help it grow, it is changed in the liver into nitrogenous waste and is secreted. This is why doctors warn about the excess consumption of foods like meat, fish, and eggs.
