Would you like to merge this question into it? Weigh each bag separately using an electronic balance and record the initial mass on a table Table 1. Before attempting to perform a lab, read the lab's protocol in its entirety, look over the relevant supplemental materials, and gather all of the necessary materials.

The next day, record the temperatures of the sucrose solutions in each beaker. The greatest surface to volume ration causes he biggest change in g total volume. Testing the Hypothesis of Independent Assortment A monohybrid cross considers the inheritance of a Before the plants have matured, This way you could prove whether or not the dissolved oxygen has an effect on the lifespan of the fish.

That should be just up the vine on the tree near you. Using a metric ruler, measure the distance in centimeters cm that the white vinegar diffused into each cube.

Solved October 09, mature in one growing season, and you have access to a large garden in which you can cultivate thousands of pea plants. Measure and pour 10 mL of each of the four prepared solutions into a separate graduated cylinder.

Assessment questions similar to those on the AP exam might resemble the following questions, which also might arise in peer review: Discussion and Conclusions 16 pts: Limitations of the conclusions should be discussed, including thoughts about improving the experimental design, statistical significance and uncontrolled variables.

Draw conclusions - Interpret the data from the graph made in Question 7. Changes to BIOS are saved: Describe the experimental design with controls, variables, and observations.

Do background research — Utilizing at least one scholarly source, describe how the dissolved oxygen content in a body of water can effect fish populations.

Design an experiment to investigate one of your questions. Examine your data from Part 1A: X is game-dependent e. What dimensions supported the greatest diffusion percent total volume? Note potential safety issues.

Describe the background and basic issue of your chosen topic. Many will sell an upgrade if you give a credit card number. Salt is hypertonic to the inside of the cells, so cells become shrunken relative to the cell wall, and turgor pressure is decreased.

This description must provide ample detail to show knowledge of experimental design and should list the independent and dependent variables, as well as your control.

Obtain five pieces of pre-soaked dialysis tubing from the beaker of water. STructured INquiry The pores in dialysis tubing allow some molecules to freely diffuse across the membrane and some to be restricted.

First, soak 6 dialysis tubing in distilled water until you can open one end. Solved September 02, Using the metric ruler, measure the dimensions of each agar cube and record the measurements in your lab notebook. Construct a useful graph of the relationship between cell dimension to the extent of diffusion.

Low -carbohydrate diets can reduce iron deficiency symptoms. Exercise caution and respect the safety of yourself and others at all times. Last name, underscore, First Initial, underscore H1.The new AP Biology curriculum framework; AP Biology lab manual, AP Biology Investigative Labs: An Inquiry-Based Approach ; and AP Exam reflect this emphasis on inquiry and reasoning and the quantitative skills these processes entail.

Lab 1: The metric system – measurement of length and weight Introduction The scientific community and the majority of nations throughout the world use the metric. m: ( + 47)/2 = 3) Change of mass indicates whether some water has went into the bag or out of the dialysis bag. 4) A hypothesis that this experiment is designed to test: If there is no substance in the dialysis bag, then water will not go into the bag because water follows higher concentrations of "salts".

Scientific Method

Bio Lab Answers  Lab 1, Exercise 1 • Based on the information in Table 2, what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point, the number of fish declines slightly.
