Chapter 9 1. Organisms that can manufacture their own chemical energy sources are called _____________. 2. ________ depend on energy stored in chemical bonds by autotrophs for their food energy. 3. Simple molecules are further broken down in cells in a process called _________‚ during which energy stored in their chemical bonds is used to power the production of ATP. 4. Glucose is broken down to carbon dioxide and water in organisms which breathe air in a process called as ________ respiration

Allison hernandez Yañez Grupo 2 A0141117 3 September 2014 A) Why is Carbon important? What makes Carbon so unique? 1.-Because this element have four valence electrons B) What are macromolecules? What is a monomer? What is a polymer? What is polymerization? 2.- A macromolecule is a very large molecule commonly created by polymerization of smaller subunits. In biochemistry‚ the term is applied to the three conventional biopolymers (nucleic acids‚ proteins‚ and carbohydrates)‚as well as non-polymeric

Categories of diseases Physical disease Results from permanent or temporary damage to the body Infectious diseases Organisms that cause disease inside the human body are called pathogens Bacteria and Viruses are the best known pathogens. Fungi‚ protists and parasites can also cause disease Diseases are said to be infectious or communicable if pathogens can be passed from one person to another. Examples: Influenza (’flu) Influenza is a virus which causes a severe form of respiratory tract infection

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:

1. In some ways‚ chlorophyll can be thought of as a solar panel like the ones used to generate electricity at power plants. Using terms such as granum‚ photosystem‚ ATP and chlorophyll‚ explain this comparison. This comparison of a chlorophyll being thought of as a solar panel like the ones used to generate electricity at power plants can be explained as a chlorophyll would be the solar panel‚ a photosystem would be a specific arrangement of the panels‚ granum would be a stack of solar panels‚ and

BSC2011C Final Review Unit 1 Review Ch. 25‚ 22‚ 23‚ 24‚ 26‚ 19‚ 27 Ch. 25 1. Life is metabolism and heredity. Metabolism is the mechanism that creates order and complexity from chaos‚ by acquiring and expending energy. Heredity is the ability of an organism to copy itself and it is broken down into: i. Multiplication‚ ii. Inheritance‚ iii. Variation. 2. DNA codes via RNA for 20 of naturally occurring amino acids. Amino Acids are the building blocks of proteins and bodies. DNA stores and transmits

Mitochondrion (plural‚ mitochondria)‚ is found in nearly all eukaryotes. Plants‚ animals‚ fungi‚ and protists all have mitochondria. Mitochondria are large enough to be observed with a light microscope and were first discovered in the 1800s. For many years after their discovery‚ mitochondria were commonly believed to transmit hereditary information. It was not until the mid-1950s when a method for isolating the organelles intact was developed that the modern understanding of mitochondrial function

by the environment around it. Cephalization – A grouping of sensory organs and nervous cells in the anterior (front / head) region of an organism. Choanocyte – The collar cells in sponges. These are very similar to choanoflagellate which are the protists that evolutionarily predated animals. Cohort – A group of individuals of the same age in a population. Commensalism – A symbiotic relationship between organisms in which one organism benefits and the other is not affected. Community – An assemblage

Determining the Effect of Light Intensity on Photosynthesis Avalon Pernell‚ et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away
