MIZZOU BIO 1500 EXAM 3 BUSH | THE SMART WAY TO
PASS | REAL TESTS, REAL RESULTS!
Describe an effective experimental design to determine whether an environmental variable
imposes selection on a trait. - Answer: -need multiple generations
-need a control group
-need different levels of oxygen
-need a small organism that reproduces quickly
-need a confined environment
How does natural selection cause dramatic changes in phenotypes? - Answer: Different
levels of oxygen can change body size, certain phenotype survives, reproduces over
generations to become popular in populations. Higher oxygen levels means animals can
grow larger and still maintain the supply of oxygen to their muscles.
What are the four categories of Organic Molecules? - Answer: 1. Carbohydrates
2. Lipids
3. Proteins
4. Nucleic Acids
What is an organic molecule? - Answer: A molecule that contains a carbon.
What are some examples of carbohydrates? - Answer: Glucose, starch, glycogen,
cellulose, chitin.
What are some examples of lipids? - Answer: Fats, oils, waxes, olive oil, bees wax, bacon
fat.

, When a fat is 'saturated', what is it saturated with? - Answer: H2
What are the building blocks of proteins? - Answer: amino acids
What are the building blocks of nucleic acids? - Answer: nucleotides
What are the building blocks of carbohydrates? - Answer: simple sugars
(monosaccharides)
What are the building blocks of lipids? - Answer: fatty acids and glycerol
What is cellulose? - Answer: Polysaccharide consisting of glucose monomers. The main
constituent of a plant cell wall and of vegetable fibers
Which would have the most cellulose?
-steak
-bowl of ice cream
-mushroom omelet
-serving of broccoli - Answer: serving of broccoli
Phospholipids are important components of which cellular structure?
-membranes
-ribosomes
-mitochondria
-chromosomes - Answer: membranes
What is the outcome of dehydration? - Answer: Two molecules form a chemical bond.
