Adriana Gutierrez AP Biology Lab 9 Analysis 1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The independent variable of this experiment are the environmental factors that you are testing on the rate of transpiration‚ so our independent variables would be bright light‚ fan‚ dark‚ and misted. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants

research allows me to spend my free time productively and allows me to exercise my memory and comprehension in a positive light. Furthermore‚ the importance of education has pushed me to willingly study often and seek outside help when needed. Recently‚ my AP Physics class met on a Saturday morning to help each other study for an upcoming test. Explaining and helping others understand a topic not only strengthens your own knowledge of the subject‚ but makes a positive impact on someone else’s educational

How well did the results compare with your prediction? __ The molecules were to large to go through. My results matched._ 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? __The albumin was not able to go through and the glucose did. I predicted that neither of them

Melissa Fellin 10/6/13 A.P. Psych Review Intro There are two communication systems in the brain The Nervous System and the Endocrine System Nervous System: extensive network of nerve cells that carry messages in pulses of electrical and chemical energy throughout the body. This is the network that first comes to your rescue by accelerating you heart and tensing your muscles for action. Endocrine System: a slower acting communication network that sends a follow up message that

Redox Titration Lab ABSTRACT: In this lab‚ 0.010 M purple-colored potassium permanganate solution was standardized by redox titration with iron (II) ammonium sulfate hexahydrate (FAS). The average mass of the three flasks of FAS was 0.483 grams. Once the concentration of the standard solution of KMnO4 (aq) was determined‚ it was used to determine the concentration of Fe2+ in iron pills. On average‚ there was 0.01813 L of solution used. With this information and the balanced net-ionic equation

The purpose of the making alum from aluminum lab was to create alum from a series of chemical reactions involving aluminum. Small pieces of an aluminum can were cut and measured before being taken through a series of chemical reactions. This process involved filtering out waste product that was no longer needed in the reaction by using Whatman #4 filter paper and an aspirator. The first reaction that took place was placing aluminum pieces into the strong base NaOH and then heating it. This reaction

Hypothesis 1: It was hypothesized that the growth and seed pod production in the standard plants would increase when less competitors were present and that growth would be more affected by competition than seed pod production would be. The data in Figure 1 and Figure 2 support this hypothesis; the standard plant grew the most when it was in a container alone and‚ on average‚ produced more seeds when no competitors were present (Figure 1). Though growth and seed pod production had similar trends
