Geological features including; mountains, island arcs, earthquakes, volcanoes, and seafloor spreading are all found at tectonic plate boundaries. An earthquake occurs when built up stress is finally released at a fault, releasing stored energy in the form of waves that cause shaking of the Earth. Soil is a valuable global resource and has given characteristics. Soils are formed when parent material is weathered, transported, and deposited.
Soils are generally categorized based on their composition and organic material.Case 1845b engine
The properties of soil can be tested and indicate the biological potential of soil in agricultural uses. The atmosphere has varying properties and composition of gases that can be organized into layers. The layers of the atmosphere is organised into layers based on temperature gradients.
These include the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The Coriolis effect is the flow of air and water from the equator to the poles and back in circular motions based around the world oceans. This exchange of heat is driven by intense solar radiation arriving at the equator and results in atmospheric circulation. Weather is the short term change in atmospheric conditions while climate is long term trends in a given ecosystem.

This is the core document for this course. It clearly lays out the course content and describes the exam and the AP Program in general. It now reflects the new unit structure for This document details the updates made to the course and exam description CED in September It includes printable copies of the updated pages, which can be used as replacement sheets in your CED binder.
This document details how each of the sample free-response questions in the CED would be scored. The framework specifies what students must know, be able to do, and understand, with a focus on big ideas that encompass core principles and theories of the discipline.
The framework also encourages instruction that prepares students for advanced environmental science coursework. The AP Environmental Science framework is organized into nine commonly taught units of study that provide one possible sequence for the course. As always, you have the flexibility to organize the course content as you like.
The new AP Environmental Science framework included in the course and exam description outlines distinct skills, called science practices, that students should practice throughout the year—skills that will help them learn to think and act like environmental scientists. Higher education professionals play a key role developing AP courses and exams, setting credit and placement policies, and scoring student work. The AP Higher Education site features information on recruitment and admission, advising and placement, and more.
This chart shows recommended scores for granting credit, and how much credit should be awarded, for each AP course. Your students can look up credit and placement policies for colleges and universities on the AP Credit Policy Search.

Catechol, a natural substance found in plants, reacts with oxygen to produce benzoquinone and water, as represented by the chemical equation above.
The reaction is catalyzed in plants by the enzyme polyphenol oxidase. Accumulation of benzoquinone in plant tissue results in the gradual appearance of a brown color. A student observes that lemon juice pH 2 slows the browning of apple slices. The student claims that lemon juice slows the browning process by altering the activity of polyphenol oxidase.
To test the claim, the student distributes equal amounts of a dilute catechol solution to 6 identical test tubes. The pH of each solution was adjusted as shown in the table, and the initial absorbance was recorded. Equal amounts of polyphenol oxidase were added to each reaction tube. After 10 minutes at room temperature the absorbance of nm light A was measured for each sample.
Solutions containing greater concentrations of benzoquinone absorb more light. The changes in A are shown in the table below. Explain your estimate by connecting the experimental results to the structure and function of proteins. Predict how the browning of apple slices would be affected in a strain of apples that was genetically engineered to lack functional copies of the gene encoding polyphenol oxidase.Cloud key gen2 factory reset
Justify your response. Ten mL of a concentrated starch solution and 1. The amount of product maltose present was measured every 10 minutes for an hour. The results are given in the table below. Graph the data on the axes provided and calculate the rate of the reaction for the time period 0 to 30 minutes. Explain your predicted results. Identify TWO environmental factors that can change the rate of an enzyme-mediated reaction.
Discuss how each of those two factors would affect the reaction rate of an enzyme. You are not limited to the three properties discussed in part a :.
For each type, describe its role in determining protein structure. Explain the genetic basis of the abnormal hemoglobin. Explain why the sickle cell allele is selected for in certain areas of the world. The relationship of structure to function is one of the major themes in biology. Water potential in potato cells was determined in the following manner. The initial masses of six groups of potato cores were measured. The potato cores were placed in sucrose solutions of various molarities.
The masses of the cores were measured again after 24 hours. Percent changes in mass were calculated. The results are shown below.
