Reflection: SS Chapters 6 & 7 I believe that there is much that we take for granted in our world today. One of these things we take for granted in the instant “treatment” for plants. We do so without even a second thought or consideration and continue to let it happen year after year. We also take for granted our everyday dependencies that stem from nature. I then question what it would take for us to realize our dependency on nature and to respect it as such. On page 73 of the reading‚ it discusses

BI 101 Spring 2013 EXAM II This exam covers chapters 4-6. This is an open note & open book exam‚ but all questions should be answered in your own words. Please include the question immediately before each answer‚ and the test is due at the beginning of the lecture following the lecture that completes the discussion of chapter 6. Further notes: On each compare and contrast question‚ 50% of the score will focus how well you ‘compare’ the items (i.e. how the items are similar) and 50% of the

AP ESSAY ANSWERS: 16-20 1. Information transfer is fundamental to all living organisms. For TWO of the following examples‚ explain in detail‚ how the transfer of information is accomplished. A) The genetic material in one eukaryotic cell is copied and distributed to two identical daughter cells. B) A gene in a eukaryotic cell is transcribed and translated to produce a protein. C) The genetic material from one bacterial cell enters another via transformation‚ transduction or conjugation

INTRODUCTION Levels of organization (cell to biosphere) and characteristics of life Levels: Cells->tissue ->organs & organ systems->organisms->populations->communities->ecosystems-> biosphere Characteristics of life: Cell and Organization: Each cell can only do the job it is tasked with. Example: brain cells Energy Use and Metabolism: Energy is needed many organisms. Energy is utilized in chemical reactions Response to Environmental Changes: responds to stimuli Regulation and Homeostasis: ex:

Calvin Williams Chapter 20 1. Advances in recombinant DNA technology allow scientists to work with smaller fragments of DNA‚ give them more tools to dissect and analyze DNA‚ and also allow for them to make many copies of a strand of DNA. 2. Restriction enzymes are made by bacteria to cut up invading DNA. They target specific base sequences in the DNA and then work to cut out those sequences from the DNA. 3. When a restriction enzyme cuts out a portion of DNA‚ it will sometimes leave a sticky

Lesson 3 Living things are made up of cells (based on a universal genetic code)‚ they obtain and use materials and energy to grow‚ develop‚ reproduce‚ respond to the environment‚ maintain a stable environment‚ and change over time. The study of biology revolves around several interlocking big ideas: the cellular basis of life; information and heredity; matter
