Answer: changing the sequence of amino acids in a protein.
==================================================
Question: Which of the following is an example of the founder effect?
Answer: Small group of iguanas floats to an island, starts a new population.
==================================================
Question: Which statements can apply to

eukaryotic cells?


I. Unicellular

II. Phospholipid cell membranes

III. DNA stored in plastids

IV. Enclosed cytoplasm

V. Double-walled nuclear membranes
Answer: I, II, III, IV, V
==================================================
Question: Which statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration?
Answer: The products of photosynthesis serve as the reactants in cellular respiration to provide chemical energy.
==================================================
Question: Why does secondary succession have more species diversity than primary succession?
Answer: Secondary succession has more species diversity due to the microorganisms that survived in the soil.
==================================================
Question: How do stem cells know what type of cells to differentiate into?
Answer: Signals from chemicals in the organism or from the environment determine which genes will be turned on and off.
==================================================
Question: In the food chain, how much energy will make it to the trophic level of the sharks if the producers have 100,000 calories?
Answer: 10 calories
==================================================
Question: A model of a biological process is shown. What is the purpose of this process?
Answer: To translate the genetic code into a specific sequence of amino acids
==================================================
Question: An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram/evolutionary tree, such as the one shown below, is based on molecular data. It can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor.

Which statement is best supported by the information in this dendrogram/evolutionary tree?
Answer: Lesser pandas are more genetically similar to raccoons than they are to giant pandas.
==================================================
Question: The complex carbohydrates pictured below are made by linking molecules of glucose. In all three complex carbohydrates, the subunits of glucose are bonded together differently. Because they have different structures, they most likely
Answer: perform different functions
