AP Biology Study Guide Chapter 11 1. Categorize chemical signals in terms of the proximity of the communicating cells. Local signaling – a. Paracrine signaling – a secreting cell acts on nearby target cells by discharging molecules of a local regulator (a growth factor‚ for example) into the extracellular fluid. b. Synaptic signaling – a nerve cell releases neurotransmitter molecules into a synapse‚ stimulating the target cell. Long distance signaling- c. Hormonal signaling – specialized

Biology - Main Questions And Answers: Complete the table with a tick if the statement in the first column is true‚ for each process. Write a simple equation to show how ATP is synthesised from ADP: ADP + Pi ATP Give two ways in which the properties of ATP make it a suitable source of energy in biological processes: 1. Energy released in small/suitable amounts 2. Soluble 3. Involves a single/simple reaction Humans synthesise more than their body mass of ATP each day.

Chapter 1 Reading and Study Guide Why This Chapter Matters 1. We are living in the golden age of biology. Biological discoveries revolutionize medicine‚ change agriculture‚ and impact human culture. 2. Life is united not by a single trait‚ but by a common set of characteristics. Appreciating what it means to be living is as complex as life itself. 3. Life exists at many levels of biological organization. Understanding how these levels interrelate provides insight into the mechanisms of living systems

Reading Guide for Chapter 35 – The Vertebrates 1. What are the five features of the chordates? • A hollow dorsal nerve cord just beneath the dorsal surface of the animal. In vertebrates this differentiates into the brain and spinal cord. • A flexible rod called the notochord that’s on the dorsal side of the primitive gut in the early embryo‚ present at some developmental stage in all chordates‚ located just below the nerve cord. May persist in some chordates; in others‚ it is replaced by

Unit 3 - Evolution Notes Evolution involves change over time....from a biology standpoint evolution looks at how organisms change over long periods of time over many generations and hundreds of thousands of years. Source of Genetic Change Mutations are the source of genetic change * Neutral mutations - do not seem to benefit or harm the organism * Harmful mutations - negatively affect the life of organisms * Beneficial mutations - positively affect the life of organisms Artificial

Section 1 : Identifying the Genetic Material Griffith’s Experiments In 1928‚ Frederick Griffith‚ a bacteriologist‚ was trying to prepare a vaccine against pneumonia. A vaccine is a substance that is prepared from killed or weakened disease-causing agents‚ including certain bacteria. The vaccine is introduced into the body to protect the body against future infections by the disease-causing agent. Griffith discovered that harmless bacteria could turn virulent when mixed with bacteria that cause

Evolution is a theory in which organisms change over time and become either better or more complex. ( 1 ) Charles Darwin‚ the Father of the Theory of Evolution‚ discovered that similar birds had adopted different beaks (finches 2 ). And thus‚ the theory of evolution‚ already placed in Darwins head by his grandfather‚ (
