Ap Bio Review Chapter 6 Multiple Choice Answers
In the multiple choice department of the AP Biology exam, yous will accept 90 minutes to reply threescore multiple pick questions and vi grid-in items. The multiple option questions are composed of two types of questions, stand solitary and data questions. Below nosotros provide practice questions for each blazon and strategies to observe the correct answer in the alloted time.
What Are Stand Solitary Questions?
Stand up alone questions on the AP Biological science test are your average multiple choice question and make upwards a fiddling over half of the questions in the section.

What Are Data Questions?
Information questions on the AP Biological science examination are a series of questions about a single data set, which are commonly represented in graphs, charts, or as an experiment summary.

Stand Alone Question 1
During photosynthesis
A. light reactions produce sugar, while the Calvin cycle produces O 2 .
B. light reactions produce NADPH and ATP, while the Calvin bike produces saccharide.
C. light reactions photophosphorylate ADP, while the Calvin cycle produces ATP.
D. the Calvin bicycle produces both sugar and O 2 .
Answer
The correct choice is B
Light reactions, which convert solar energy into chemical energy (ATP, NADPH) in the thylakoid membranes, fuel the Calvin wheel's production of sugars in the stroma.
Stand up Alone Question 2
Organisms that reproduce sexually exhibit zygotic, gametic, or sporic meiosis. One manner to determine the type of life bike an organism has is by
A. observing embryonic development.
B. comparing the diploid and haploid forms of the organism.
C. determining when in the life cycle fertilization occurs.
D. determining if gametes are multicellular or unicellular.
Data Question ane
The cecum is a portion of the big intestine located near the junction of the pocket-size intestine and the large intestine. The post-obit table lists the diets of several vertebrates, besides as the average length of the cecum equally measured in 20 individuals of that species.
Based on the following data, which of the following conclusions is most plausible?
| Species | Boilerplate Cecum Length | Diet |
| A | 40.1 cm | herbivore |
| B | 5.7 cm | omnivore |
| C | half-dozen.8 cm | carnivore |
| D | 30.2 | ruminant |
A. The cecum can become a vestigial structure in carnivores, since it is shorter in species B and C than in species A and D.
B. The cecum evolved to have an important role in the digestion of protein, since it is shorter in species B and C than in species A and D.
C. Species A is more closely related to species D than to species B, considering A and D are both herbivores.
D. Species B and C have a common antecedent, since the cecum in species B and C is approximately the same length.
Answer
The right pick is A
The information here suggest that the cecum is iv to five times longer in species that consume plant matter for their diets (A and D) compared to those that swallow at least some meat (B and C).
Of the statements listed, the but one that logically follows is (A): in carnivores, the cecum becomes unnecessary, and starts to shorten. (B) is the opposite of what we expect; it would exist logical if it played a prominent office in digesting carbohydrates. (C) The information on cecum length and nutrition are bereft to describe conclusions nearly the relatedness of species, so rule out (C) and (D).
Information Question ii
The following diagram shows free energy transformations within a cell. Each form of free energy is represented by the symbols E I–E IV. Two cellular organelles are represented by the letters A and B. Answer the following questions about the various processes depicted in the diagram and nearly the cell in which they are occurring.
Question ane
What class of energy is represented by E Ii?
A. Radiant energy in the form of photons
B. Chemical free energy being stored in the bonds of glucose
C. Chemical energy in the form of ATP
D. Chemical energy released by glycolysis
Question 1 Answer
The correct choice is C
The reaction occurring in organelle A is photosynthesis, as indicated by the splitting of water and fixation of CO 2 . The first reaction in this organelle represents the calorie-free reactions, in which the dominicus's energy is converted to chemical free energy in the form of ATP (E 2).
Question 2
If the transformation depicted in organelle B requires oxygen, what form of energy is represented by E IV?
A. Radiant energy in the form of photons
B. Chemical energy being stored every bit glycogen
C. Chemical free energy in the form of ATP
D. Chemical energy released by glycolysis
Question 2 Reply
The correct choice is C
The reaction occurring in organelle B is cellular respiration, as indicated by the release of energy stored in the bonds of glucose. Because the question specifies that oxygen is required, the procedure depicted must show aerobic respiration rather than glycolysis. The class of energy released in aerobic respiration is chemical energy in the form of ATP (E Four).
