Green River College: BIOL 100 Unit 3 Notes Latest Updated Chapter 6: Energy for life Learning Objectives: 1. Identify the cellular structure where photosynthesis occurs and describe its function. 2. State the overall chemical equation for photosynthesis. 3. Recognize what is meant by the terms reduction and oxidation. 4. Describe the function of photosynthetic pigments. 5. Explain the flow of electrons in the light reactions. 6. Explain how ATP and NADPH are generated in the light reac...

What are the 2 theories of evolution? Explain each - correct answer Gradualism- geologic changes result from slow, gradual, continuous process Punctuated Equilibrium- Long period of stasis punctuated by short bursts of significant change. What was Lamarck's theory and why was it wrong? - correct answer Lamarck = Inheritance of Acquired characteristics- traits acquired during lifetime could be passed on What is natural selection - correct answer Comptetition for limited resources re...

Adaptation- - correct answersThe adjustment or changes in behavior, physiology, and structure of an organism to become more suited to an environment. Aerobic- - correct answersA process that requires oxygen. Allele -An alternative form of a gene. An example would be genes that encode eye color—some encode blue eyes (one allele), while others encode brown, green, or hazel eye colors (other alleles). - correct answers amino acids - - correct answersA small organic molecule with the stru...

Honors Biology Evolution Questions and Answers Graded A+ What is natural selection? Natural selection is the process where organisms with traits best suited to their environment are more likely to survive and reproduce. How do mutations contribute to evolution? Mutations introduce new genetic variations, which can lead to new traits that may be advantageous in a changing environment. What is the significance of fossil records in understanding evolution? Fossil records pro...

Natural Selection - Answer-A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits. Evidence of Evolution - Answer-1) Fossil Record 2) Embryology 3) Homologous Structures 4) DNA 5) Vestigial Structures common ancestor - Answer-the most recent ancestral form or species from which two different species evolved homologous structures - Answer-Structures in different species that are simila...

Biogeography Analogous structures - Structures that look the same, but not because they shared a common ancestor homologous structures - Structures that look the same because they did share a common ancestor James Hutton - Geologist that believed in deep time (meaning the earth is super old). Charles Lyell - Believed earth of 4.6 billion years old Got idea from James Hutton Carl Linnaeus - Created binomial nomenclature Alfred Wallace - English contemporary to Darwin Published his resea...

IB Biology: Evolution Questions and Answers Already Passed What is a theory? A comprehensive explanation of some aspect of nature (vs a hypothesis, which is just a prediction as to the result of an experiment). What were some ideas from Darwin's time that influenced his work? French naturalist Buffon in the mid-1700s studied fossils and said the Earth must be older than previously assumed; Lamarck in the early 1800s proposed that life changes over time. Define acquired vs heritab...
