Introductory Questions #1 Name the seven main properties of life. (Pg. 3) Which of the hierarchial levels of biology is the lowest in regard to carrying on and sustaining all life activities and is the fundamental unit of life? (pg 5) Introductory Questions #1 3. In your own words briefly describe what ?emergent properties? are. 4. How is negative feedback different from positive feedback? (pg. 11) What do these mechanisms do for a living thing? 5. Name the three domains of life. Which domain includes four out of the six kingdoms of life? 6. Why is natural selection considered the ?mechanism? for evolutionary adaptations to occur? 7. How is a hypothesis different from a theory?

Assignment 2 ? Chemical Bonds In this world there are many different kinds of living organisms. All organisms are composed of atoms, that bond together to make the necessary components of a living organism. There are three identified chemical bonds that are recognized, they are ionic bonds, covalent bonds and hydrogen bonds. All bonds are not created equal, just ask the electrons!

Chapter 6: The Periodic Table & Atomic Structure Section 6.2: The Electromagnetic Spectrum Monday, September 15, 2014 3:06 PM Visible Light - portion of electromagnetic spectrum that we can see, typically with wavelengths between 400 / 700 nanometers ? Electromagnetic Spectrum - various forms of light, consisting of oscillating electric and magnetic fields ? ? ? The Wave Nature of Light ? Wavelength - distance between corresponding points on a wave Amplitude - height of the wave from equilibrium position Frequency - number of cycles of a wave passing a certain point per second (measured in Hz) **note: amplitude corresponds with brightness, wavelength and frequency correspond with color ? Speed of light ( c ) : c = lamda x v = wavelength x frequency ? The Particulate Nature of Light

Campbell's Biology, 9e (Reece et al.) Chapter 2 The Chemical Context of Life This chapter presents basic chemical principles for understanding the chemical context of living organisms, from atomic structure to the nature of chemical bonds and an introduction to chemical equilibrium. These questions focus on elements most important to life or the study of life, including the elements that comprise organic molecules and important trace elements. Some isotopes are important in geologic dating and in biological tracer studies. How elements participate in forming different types of chemical bonds is essential to mastering subsequent topics on the behavior and properties of biological molecules, structures, and energy metabolism. Multiple-Choice Questions

Atomic Structure Definitions ? Acceleration ? The stage of mass spectrometry during which the movement of the ions of the sample is speeded up using a series of negatively-charged plates. ? Atomic number ? The number of protons in the nucleus of an atom of an element. Represented by the symbol Z. Also called the proton number. ? Deflection ? The stage of mass spectrometry during which the beam of ions is bent by a particular amount, depending on its mass-to-charge ratio. This is achieved using an electromagnet. ? Detection ? The stage of mass spectrometry during which the ions strike a collector plate, producing a mass spectrum for analysis. ? Diatomic ? A molecule consisting of two atoms. ? Electromagnet ? The part of a mass spectrometer responsible for the
