The results of the experiment are provided. In an emergency, a doctor can replace a patient’s blood plasma with a solution of 5% human albumin and 0.9% NaCl. jdmay. He mixed 1 part of the 25% solution with 4 parts of sterile distilled water. This is an advanced quiz intended for students in AP Biology. Terms and Conditions Solo Practice. Because the resulting solution was hypotonic to the red blood cells, water from the solution osmosed into the cells, causing them to burst, as in (C). Quiz over photosynthesis that focuses on how oxygen is split, providing and electron that eventually results in the formation of ATP. Biotechnology quiz, biology worksheets, plants and animals quiz, biochemistry quiz. Hundreds of multiple choice questions, all organized by topic. C. The dilution of albumin in distilled water caused the bursting of red blood cells because the solution was hypotonic to the red blood cells. Colorless colonies indicate that the cells cannot ferment lactose. A. Biology quizzes for practice. B. D. The dilution of albumin in distilled water caused the shriveling of the red blood cells because the solution was hypertonic to the red blood cells. These quizzes are topic based and are used by biology students to prepare for exams or for other students to practice their knowledge of biology themes. Choice A is incorrect because a higher rate of oxygen consumption in mitochondria would decrease ADP levels (electrons are transferred to oxygen when ADP is phosphorylated to make ATP). This quiz is incomplete! Classic . Print; Share; Edit; Delete; Report an issue; Live modes . Ch 29, 35 - 39 - Plants. To play this quiz, please finish editing it. How can the consequence of the administration of substitute plasma be explained? Varsity Tutors. Choice B is incorrect because ADP levels would be greater when ATP is utilized (ATP → ADP + Pi). Share practice link. The CollegeBoard designs the AP curriculum and AP Exam. Only colorless colonies appear from cells incubated with extract A.

Click link for practice quizzes in all content of AP BIO: QUIZ More Practice Quizzes : CLICK. Save. How is the reaction between enzyme and substrate modified by the different temperatures? Fill in your details below or click an icon to log in: Instructor-paced BETA . Played 2080 times. (A) and (B) are incorrect because the pharmacist did not err in his dilution of the albumin. The excess kinetic energy makes it harder for the substrate to bind to the enzyme. These are challenging online quizzes with answers and explanations. Which of the following is the most plausible explanation for this finding? The correct answer is (C). Practice multiple choice questions are on canvas, IT IS A GRADE . Higher than normal levels of ADP suggest that the transgenic mice are unable to convert ADP to ATP as efficiently because the mutation has impaired their mitochondria. At 30°C, the enzymes have denatured due to excess heat and the substrates have more difficulty binding to the active site. CA Privacy Policy, © Copyright Kaplan, Inc. All Rights Reserved. Only colorless colonies appear from cells incubated with extract B. C. Only colorless colonies appear from cells incubated with extract C. D. Blue colonies appear from cells grown with all three extracts. Work for Kaplan Ch 8, 9, & 10 - Metabolism. Live Game Live. (D) is incorrect because the cells incubated with extract B will appear colorless, as explained above. After treatment with enzymes, each extract is incubated with live lac− cells and grown on a medium containing an indicator. Since 2009, Next Step Test Preparation has helped thousands of students raise their scores on tests such as the MCAT, which you may face one day as well on the way to medical school! AP Biology Practice Test. GREAT ECOLOGY REVIEW. Anatomy; Cell Biology; Evolution; Genetics; Ecology; Science Methods; Classes. Most of you already have one, but if you do not you will need to create one anyway to access your AP scores. These are challenging online quizzes with answers and explanations. The dilution was incorrect, resulting in an excessive concentration of albumin that led to the shriveling of the red blood cells. Dichlorophenolindophenol (DPIP), an electron acceptor that changes from blue to clear when reduced, can be used to visually determine the rate of photosynthesis. Practice. Edit. Save. You can find links to our course goals, practice exams, and lab information is available. At 30°C, the substrate molecules have less kinetic energy than at 37°C. Edit. A. This allows the reaction to proceed more rapidly. Please note that these external links are set to match the chapter format in Campbell & Reece Biology - AP … ap_mock_test_2_answer_key.pdf: File Size: 22 kb: File Type: pdf: Download File. Privacy Policy 0. The content that will be on the midterm is listed in the document below. Can You Pass This 10th-Grade AP Biology Test? In an experiment, a solution of chloroplasts containing DPIP was divided among 4 tubes. Multiple Choice Questions. Contact Us Biology. In a respiration experiment, transgenic mice (those possessing a particular genetic mutation) were compared to wild type (normal) mice. Please note that these external links are set to match the chapter format in Campbell & Reece Biology - AP Edition 8th Edition. Choose your answers to the questions and click 'Next' to see the next set of questions. Play. The onset of photosynthesis is visible when DPIP is oxidized and changes from clear to blue. Choice D is incorrect because the solution in all four tubes was blue at time 0. D. The rate of carbon dioxide consumption in cells was lower in transgenic mice. C: DPIP acts as a substitute for NADP+ in photosynthesis. Because those cells would be unable to ferment lactose, they would appear as colorless. AP BIOLOGY MIDTERM. Click here for more AP Biology practice questions! B: Because the lac− cells contain everything necessary to construct enzymes that can ferment lactose except for the DNA with the lac+ genes, the only cells that would be adversely affected would be those incubated with extract B, which loses those genes due to the action of the DNases. AP Biology Unit 1 DRAFT. -, The Origin of Life and Natural Selection Notes, Biodiversity, Behavior, and Ecology Notes. Questions are sorted by topic and include a wide variety of bio topics as well as supporting chemistry concepts. One of the best free resources available! CollegeBoard's AP Biology Course homepage is very helpful for this course. (C) is incorrect because 30°C is actually a higher temperature than 37°C, so it makes no sense to say that the protein “denatured due to excess heat.” (D) is incorrect because substrate concentration remains constant, according to the question stem. C. The transgenic mice have impaired mitochondria, decreasing their cells’ ability to convert ADP to ATP. Posted on Apr 12, 2017. (C) is incorrect because the lac− cells contain all the RNA molecules and nucleotides necessary to transcribe and translate the lactose-fermenting enzymes, provided they have the proper genes (which they can get from extract C), so they would also appear blue. Students progress at their own pace and you see a leaderboard and live results. 76% average accuracy. According to the data, an increase in light transmittance over time is found for the tube exposed to light only. Ch 3 & 4 - Biochemistry. All six AP Biology science practices are assessed in the multiple choice section with the following exam weightings. Choice D is incorrect because carbon dioxide is released, not consumed, in cellular respiration. Edit. Start a live quiz . Delete Quiz. ch 1 - Intro To Biology. Ch 2 & 3 - Biochemistry . A. ch_1.rtf: File Size: 139 kb: File Type: rtf: Download File. D. The solution in all four tubes was clear at time 0. However, the pharmacist should have used sterile saline solution instead of the distilled water, to ensure that there was an adequate concentration of NaCl.
