Robert Brown is credited with the discovery of the cell nucleus. 4. Schleiden and Schwann’s contribution to biology was proposing that cells are the basic structural unit for plants and animals. 5. Before Virchow‚ one idea was that living things could arise from non-living and from dead matter‚ a process called ‘spontaneous generation’. 6. Person B is more

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

The presidential election in 2000 between George W. Bush and Al Gore was a close race‚ unfortunately for Al Gore‚ the election was not fair. When Florida voted the first time Bush won all 25 electoral votes‚ he won by 15‚000 votes. Palm Beach county in Florida demanded a recount because many citizens believed they voted for the wrong person due to the confusion of the ballot. The machine which counted the votes didn’t count correctly and somehow took away thousands of votes away from Gore and gave

Chapter 1- 2 CHAPTER 1 INTRODUCTION: THEMES IN THE STUDY OF LIFE OBJECTIVES Exploring Life on Its Many Levels 1. Briefly describe the unifying themes that characterize the biological sciences. 1. The cell an organism’s basic unit of structure and function 2. Heritable information: the inheritance of biological information in the form of DNA which is encoded in the nucleotide sequence of DNA. 3. Emergent properties: emerge as a result of interaction among components at the

asked “how do we communicate with students today who have grown up with technology from the beginning?” (Source B). The answer is astoundingly simple. Talk to us. Speaking to each other will always be the best form of communication possible- and it’s free. It is up to teachers to engage their students‚ and present information in creative ways. Limited technology could be useful‚ and prepare kids for the adult world‚ though the focus in classrooms should always be the teachers‚ so that students learn
