Bio 101 Review Sheet
Test #1 (Chapters 1-3)
Chapter 1 1. Cell is basic unit of life 2. Hierarchy of life figure 3. 3 Energy categories and examples of each
Producer-plants and some microbes
Consumer-humans and other animals
Decomposer-fungi and other animals 4. Energy transfers are not 100% efficient – why? Cant capture all of the energy supplied by one source a. Where does all energy for biology come from? sun 5. Homeostasis- state of internal consistency or equilibrium 6. 2 types of reproduction asexual and sexual b. Benefits to sexual reproduction benefit of tremendous variation 7. Adaptation inherited characteristics or behaviors that enables an organism to survive and reproduce

Solute, solvent, solution interactions
Solvent-a chemical in which other substances dissolve
Solution-1 or more solutes dissolved in liquid solvent 15. Hydrophobic vs. hydrophilic molecules
Hydrophobic-water fearing
Hydrophilic-water loving 16. Reactants and products in chemical reactions
Reactants-starting materials
Products-resulting materials 17. Difference between acid and base
Acid-adds H+ to the solution
Base-more OH- than H+ 18. pH scale –which is acid vs. base
Acid-less than pH 7
Base-greater than pH 7 19. 4 types of biological molecules – what is monomer for each one
Carbs, lipid, proteins, nucleic acid 20. 4 types of polysaccharide and what they do
Cellulose-plant cell walls
Chitin-exoskeleton of insects, cell walls of fungi
Starch-plant energy storage
Glycogen-animal and fungi energy storage 21. Difference between trans, unsaturated and saturated fats
Trans-fat cakes created by man
Saturated-have all single bonds between carbons
Unsaturated-have at least 1 double bond between carbons 22. Which type of cholesterol is good vs. bad – HDL, LDL 23. 4 levels of protein structure
Primary, secondary, tertiary, quarternary 24. Ways to denature a protein 25. Major differences between RNA and DNA
DNA-dioxyribose sugar, double helix
RNA-ribose sugar, single stranded
Chapter 3 1. Basic tenets of cell theory
Cell is the fundamental unit of life
All organisms made of one or more cells
All
Most enzymes work best at body temperature, higher temps will cause the enzyme to no longer work properly
37. What happens if you don’t have enough The body’s calcium needs will come out of the
Cellular respiration: C6H12O6 + 6O2 → 6CO2 + 6 H2O + 36 or 38 ATP
1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points)
8. I added the 3 ml of soap to the beaker and stirred the solution 40-50 times with a fresh pipette.
3. State the name and structure of the functional group for each type of biologically
What is the function of ribosomes? What are their two components? Ribosomes are the cellular components that carry out protein synthesis. Their two components are a large subunit and a small subunit.
Please answer these questions then place them in the drop box for this lab. Use Microsoft word if possible.
3a. Body more than five times as long as broad; front edge of dorsal fin far
A chemical reaction involving the transfer of electrons rather than molecules is classified as a Redox reaction. A reaction involving the loss of electrons is called Oxidation, and a reaction involving the gain of electrons is called Reduction. Oxidation and Reduction always occur together, as one reactant loses electrons, and the other gains them. This exchange often effects the physical states of molecules, as their solubility is changed with their charge.

The purpose of the “chi-square test” was to see if our data was in an acceptable range of a specific ratio listed above. The chi-square test took into account the expected deviations in the F2 offspring’s alleles.

Writing is something that we tend to associate with English class and not with Biology. Being able to write is very important in a Biology career because it is an important part of communication and being able to get your job done. Dr. Richard Musser, who is an Interim Chairman and a Full Professor in the biology department at Western Illinois University, specified the necessity of being able to write well. He has been in this position since July 1st 2016. Dr. Musser talked about how he had to use writing to apply for the position he is in, the several types of writing that he is responsible for, to whom he writes, the technology used and if the writing that he does gets review by others.
