BIOLOGY 203 FINAL EXAM STUDY
GUIDE QUESTIONS & ANSWERS
CORRECT 100%
Describe the steps of the scientific method - ANSWER-Observation: Use all 5
senses to see whats going on.
-Hypothesis: Make an educated guess about how something works.
-Prediction: Assume hypothesis is correct and predict the results. If... then...
-Experiment: Test your prediction
-Analysis and conclusion: Gather results and evaluate hypothesis
Gamete - ANSWERIn animals, the cell containing the daughter nuclei produced by
meiosis.
Ovum - ANSWERThe singular name for a female gamete
Solvent - ANSWERThe substance after a solution is dissolved.
Solute - ANSWERThe solution that is dissolved.
Selective Permeable - ANSWERA membrane that regulates the passage of
substances into and out of the cell, allowing some to move easily while excluding
others.
Diffusion - ANSWERThe movement of solute molecules from a region of high
concentration to one of lower concentration. Movement of water from lower
concentration to one of higher concentration
Osmosis - ANSWERThe movement of water from higher concentration to one of
lower concentration. Movement of water from areas of lower solute concentration to
higher solute concentration.
Sperm - ANSWERThe male name for a gamete
Synapsis - ANSWERThe pairing of homologues.
Zygote - ANSWERThe first cell of the new diploid generation. Formed from the
fusing of two haploid gamete nuclei.
Discuss the significance of crossing over, segregation, and independent assortment
- ANSWER
, Variable Number of Tandem Repeats (VNTR) - ANSWERResults in the cause of
variation. Originate when small segments of DNA are duplicated when only one copy
was originally present.
Explain the parts of a scientific paper - ANSWER-Title
-Abstract: 1 paragraph on what you did, why it's important, and results.
-Introduction: Inform the reader about what your research is, why it's important, and
reference others work.
-Methods: Concise description of what you did, describe what statistics you used.
-Results: Data/stats, differences. Don't analyze data.
-Discussion: Analyze data with meanings, conclusion.
-References cited
Explain the dependent, independent, and control variables - ANSWERDependent
Variable- What's changing
Independent Variable- What you're measuring
Control Variable- What doesn't change
What are Carbohydrates? What are the four types. - ANSWERCarbohydrate: simple
sugar or a larger molecule composed of multiple sugar units.
-Monosaccharides
-Disaccharides
-Polysaccharides
-Starch
Monosaccharides - ANSWERSingle sugar molecule.
Ex: ribose, deoxyribose, fructose, and glucose.
Disaccharides - ANSWERTwo joined monosaccharides.
Ex: sucrose, maltose, and lactose.
Polysaccharides - ANSWERMore than two monosaccharides joined together.
Ex: glucose
Starch - ANSWERA key glucose-storing polysaccharide in plants, an important food
molecule for humans.
Proteins - ANSWERA diverse group of macromolecules. Many are structural
components of muscle, bone, hair, fingernails, and toenails, among other tissues. All
proteins are chains of amino acids.
Benedict's Solution - ANSWERTests for carbohydrates. Small carbohydrate
molecules react upon heating with the copper-containing compound.
Lugol's Solution (IKI) - ANSWERTests for carbohydrates. Dilute solution of
potassium Iodine reacts with starch and forms deep blue/black.
Biuret reagent - ANSWERTests for proteins. The greater the number of peptide
bonds, the more intense the color reaction with Biuret.
