What are the shapes and designations of the f orbitals? The exotic‚ complex f orbital shapes are rarely shown in textbooks. General (and organic) chemistry traditionally focuses on the lighter elements‚ but the forbitals aren’t occupied in the ground state until element 58 (cerium). Even for elements beyond cerium‚ the f orbitals are deeply buried beneath the valence shell and they rarely play an important role in chemical change or bonding. However‚ the orbital shapes can be useful in interpreting

Digestive System: Shade the of the correct answer. 1. What is the digestive system? The body’s breathing system The body’s system of nerves The body’s food-processing system The body’s blood-transporting system 2. Digestion begins in the mouth. Which of the following statement is INCORRECT? The tongue aids in the digestion of the food. The saliva changes some of the starches in the food to sugar. The tongue keeps the food in place in the mouth while the food is being chewed

The purpose of this essay is to research and evaluate the digestive system effectively and extensively. Then describe the differences and indifferences of three different organisms in relation to their digestive system. The three organisms that have been chosen are the human‚ for comparative purposes‚ the Goliath Bird Eating Spider and the Cobra Lily carnivorous plant. The Human Digestive System Digestion is the breaking down of substance in the body‚ into an easier form of which it can be absorbed

Biology Mammals Grazing Herbivore: Herbivores digestive systems can consist of one of two types of insides‚ it can be a foregut fermenter where the Foregut Fermeters has two parts (a tubiform and a sacciform fore stomach) containing lots of microbes. The stomach is bigger than that of a hindgut fermenter considering its usually a bigger animal‚ the stomach has an extra chamber to help devour glucose from the cellulose (the herbivores diet is largely cellulose and is broken down by the microbes)

Each step in digestion requires energy‚ and thus imposes an “overhead charge” on the energy made available from absorbed substances The major part of digestion takes place in the

Digestive system disorders Digestive system disorders can cause a lot of discomfort. Symptoms can include gas‚ diarrhea‚ constipation‚ cramps‚ nausea and vomiting. These common symptoms can have very different causes. These kinds of symptoms can make digestive disorders hard to diagnose. Celiac disease Celiac disease occurs when the body’s immune system reacts to a type of protein called gluten. If a person eats food that contains gluten‚ the immune system will gradually damage the lining of

Digestive System: As with any system we are learning in this course‚ the structural anatomy and functions of each are the basis of your learning. Otherwise known as the alimentary canal‚ the best way to learn the digestive system structures and their functions is to follow some food through the process from beginning to end. Where does the food go? As food enters the mouth‚ both mechanical and chemical digestion begins. First the food is physically broken down by the mechanical process

Digestive Systems in Different Animals Different species of animals have different digestive systems which are adapted to their unique requirements. The type of food‚ method of food gathering and energy needs are some factors that influence the type of digestive system an animal needs in order to survive. Herbivores have a more specialised digestive system than that of a carnivore because it is more difficult to digest vegetation than meat. The teeth are flat so that grass and plant material can

Introduction The Digestive system breaks down the ingested food into absorbable forms of nutrients and absorbs nutrients‚ ions and water from the external environment of the body. It is designed to maximize digestion and absorption. The functional structures of the digestive system are the passage‚ the glands like salivary glands‚ gastric glands‚ pancreatic‚ intestinal glands and liver. Also‚ the four layers of the digestive system are mucosa‚ submucosa‚ muscularis and serosa. The digestive system is regulated
