What is Batesian Mimicry?
200
All of the following are examples of carbohydrates except: (a) glycogen (b) amylose (c) pepsin (d) maltose (e) polysaccharide
What is (c) "pepsin?"
200
This statement best describes opportunistic, or r-strategy, organisms. (a) They reach sexual maturity rapidly. (b) They reach their adult size slowly. (c) They attain a large body size. (d) They live for a long time. (e) The size of their population remains fairly constant.
What is (a) "they reach sexual maturity rapidly?"
200
The nucleolus functions in the production of... (a) Golge apparatus (b) microtubules (c) mitochondria (d) ribosomes (e) endoplasmic reticulum
What are (d) "ribosomes?"
200
This can be used to determine the rate of enzyme-catalyzed reactions. (a.) Rate of disappearance of the enzyme (b.) Rate of disappearance of the substrate (c.) Rate of disappearance of the product (d.) Change in volume of the solution (e.) Increased activation energy
What is (b.) "Rate of disappearance of the substrate?"

This is the largest population that an ecosystem can sustain.
What is carrying capacity?
300
Hydrophilic properties are characteristic of all of the following except: (a.) polar molecules (b.) molecules soluble in water (c.) molecules that readily ionize in water (d.) the long hydrocarbon chain components of some molecules (e.) the hydroxyl group
What is (d.) "the long hydrocarbon chain components of some molecules?"
300
This level of organization includes all of the others. (a) population (b) ecosystem (c) community (d) organism (e) habitat
What is (c) "ecosystem?"
300
The function of this organelle directly requires oxygen. (a) ribosome (b) mitochondria (c) nucleus (d) golgi apparatus
What is (b) "mitochondria?"
300
This is the explanation of why enzymes lose function at high temperatures.
What is "the protein that makes up the enzyme denatures (loss of tertiary structure) and the active site loses proper conformation?"
300
This behavior is rare in organisms, and reduces an individual organism's fitness, but increases the fitness of other individuals in a population.
What is altruistic behavior?
400
In a lake, acid rain has lowered the pH to 3. This results in a hydrogen ion concentration of: (a.) 3.0 (b.) 10^-11 (c.) 10^-3 (d.) 103 (e.) 3%
What is (c.) "10^-3?" because pH = -log[H+]; therefore, 3 = -log[10^-3]

400
The following statement regarding coenzymes is TRUE. (a) They are essential for metabolic reactions in animals but not in plants. (b) They can facilitate metabolic reactions by combining with enzymes. (c) They are minerals that alter the pH of cells and thus increase the probability of chemical reactions.
