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

* 3 types of fungi * decomposer fungi‚ absorb nutrients from nonliving sources * parasitic fungi: absorb nutrients form living sources * mutualistic fungi: both fungus and host organism benefit from relationship (example is mycorrhizal fungus and plant roots) * Mycelium is made up of threads called hyphae. * hyphae may have septate ( cross walls that separate nuclei and cytoplasm into cells) * hyphae may be coenocytic which means lack of such cross

isn’t undergoing mitosis is known as chromatin. 4. Why is mitosis important for multicellular organisms? Mitosis is important for multicellular organisms for many reasons. For an example‚ one reason is that wounds and cuts can be healed and repaired by adding new cells in the cell division. Another reason is so that chromosomes are equally distributed among two daughter cells which helps in maintaining the similar amount of genetic

1P Paper Towel Absorbency Experiment Write-Up Purpose: The purpose of this experiment is to conduct a valid experiment‚ realize that the way I conduct an experiment influences the data‚ and I want to know which paper towel has the higher absorbency times. My hypothesis is that bounty will be the quicker picker upper Materials and Methods: As a class we chose that our control out of the brands provided (Bounty‚ Viva‚ Wal-Mart‚ and the School brand) would be the Schools brand of paper towel

I myself have always enjoyed anything written or directed by Tim Burton because of his sense of horror and his creative abilities. The characters are redefined

Drew Staples 6/12/14 Properties of water Question Does mixing water with other substances change it’s boiling point. Research The boiling point of a liquid is when the temperature causes the vapor pressure to be equal to the air. Air density will change waters boiling point. High altitudes give water a lower boiling point. Hypothesis If the water is less dense then it will boil faster and the boiling point will be lower.

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
