by taking over the fight or flight responses of the nervous system. It supports activities that are related to storing energy rather than releasing it. These activities include salivation‚ increased blood flow to the gastrointestinal system and digestion while the sympathetic nervous system inhibits salivation and stimulates glucose release. After exercise the parasympathetic system facilitates an increase in blood flow to the stomach and a decrease in blood flow to the skeletal muscles. There is

The three particles that make up atoms are d. protons‚ neutrons‚ and electrons. Which of the following statements about a compound is true? A. The physical and chemical properties of a compound are usually very different from those of the elements from which it is formed. A covalent bond is formed as the result of b. sharing electrons. In a water molecule‚ shared electrons spend more time around the oxygen atom than the hydrogen atoms. As a result‚ the oxygen atom is a. slightly negative.

Development though the life stages Physical effects on aging In older age (64+) many things happen on the inside and the outside the body. As you hit older age‚ you will start to notice that many things will happen on the outside of your body. Your hair may start to go grey or you may start to go bald. The hair goes grey because as you get older your hair loses pigment which is the colouring in your hair. Also your skin may lose elasticity; this means your skin may appear to get wrinkles. Your

opposite reaction would be anabolism; this is when energy is used to build complex structures from simple cells. Cellular respiration Energy is produced from the food we eat. The cells break down the energy stored in the food through a system known as cellular respiration. Cellular respiration means the food is broken down by the cells to produce the energy. Cellular respiration is the process of changing food molecules to water‚ carbon dioxide and energy. Metabolism in the Body The Digestive system

Final Biology Exam Review Unit One: Cellular Processes Definitions: Apoptosis – Known as cell suicide‚ lysosomes break open and decompose the entire cell. Triglyceride – A lipid molecule composed of glycerol and three fatty acids. Simple diffusion – Movement of particles from an area of high concentration to an area of low concentration. It goes through the phospholipid bilayer. Facilitated diffusion – Diffusion of particles through the cell membrane‚ assisted by transmembrane proteins

Animal Biology - Study Guide 2013 Professor: Marty Leonard Room 4060 LSC e-mail: mleonard@dal.ca Below you will find textbook readings and a summary of the lecture material for each of the seven lectures in the Animal Biology unit. I would be pleased if you read through each chapter‚ however‚ I will only test you on the lecture material that corresponds to the sections of the textbook that I indicate below. You will notice that in some of the assigned sections there is material that

Enzymes All enzymes are globular proteins and round in shape They have the suffix "-ase" Intracellular enzymes are found inside the cell Extracellular enzymes act outside the cell (e.g. digestive enzymes) Enzymes are catalysts → speed up chemical reactions Reduce activation energy required to start a reaction between molecules Substrates (reactants) are converted into products Reaction may not take place in absence of enzymes (each enzyme has a specific catalytic action) Enzymes catalyse

Student Name: Name of Group Members: Date: Introduction: In this lab‚ you will be examining many characteristics of a rat’s anatomy. Dissections help researchers get a 3-dimensional picture of how the systems of a body work together. Now you’ll have the opportunity to see how the respiratory‚ digestive and circulatory system are arranged spatially. The Classification of the Rat (Rattus norvegicus): Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Mammalia
