AP Biology Name: Chapter 51 Guided Reading 1. How do behavioral ecologists define behavior? Behavioral ecologists define behavior as everything an animal does and how it does it 2. What is the focus of: a. Proximate questions of behavior? Focuses on the environmental stimuli‚ if any‚ that trigger a particular behavioral act‚ as well as the genetic‚ physiological‚ and anatomical mechanisms underlying it. b. Ultimate questions of behavior? Focuses on the evolutionary significance

Fatmata Diffusion Abstract dialysis tubing is‚ made of cellulose because it’s a selectively permeable membrane. In this experiment‚ we are testing to see if the solution in the beaker moves into the dialysis bag. Which because of that‚ Introduction Diffusion and osmosis are two types of transport mechanisms. Diffusion is the movement of molecules from areas of higher concentrations to areas of lower concentration until the molecules are evenly distributed through the area. Osmosis is the dispersion

Reflection: SS Chapters 6 & 7 I believe that there is much that we take for granted in our world today. One of these things we take for granted in the instant “treatment” for plants. We do so without even a second thought or consideration and continue to let it happen year after year. We also take for granted our everyday dependencies that stem from nature. I then question what it would take for us to realize our dependency on nature and to respect it as such. On page 73 of the reading‚ it discusses

Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature‚ molecular weight‚ and movement. To test the rate of diffusion a drop of dark food coloring was added to a glass of tap water and it was timed to see how long it took for the drop to reach the bottom of the glass. This procedure was repeated three

Jhoselyn Adames June/12/2012 Scientific Critique of "_Osmosis Jones_" SYNOPSIS The 2001 film‚ _"Osmosis Jones"_‚ focuses on the representation of the human organism and the daily conflicts a body faces in order to maintain function. The film _"Osmosis Jones"_ is a film that tries to capture the attention of children ages eight to fourteen‚ by exposing the mechanisms of the human body. It is able to reveal the dangers of maintaining an unhealthy diet and some of the consequences that are associated

The purpose of the lab was to investigate osmosis‚ which was successfully achieved because there was a change in the potato’s mass which was due to the net movement of water either into the potato cells or out of the potato cells. In the 0.400M solution‚ the potato decreased in mass‚ this was due to the reason that the solution was hypertonic. There was a higher concentration of solute and lower concentration of water in the solution than there was in the potato cells. This led the water to travel

showed that amount of oxygen produced increased about 10% a minute until it sort of equilibrated at 4 minutes and didn’t change to the fifth minute mark. If we were to change anything we did in the experiment‚ we would make our comparisons to the chart more precise. Overall we thought it was successful. Part 2 In part two of the enzyme lab‚ we have 12 different test tubes‚ six of each (#1‚ 2‚ 4‚ 9‚ 11‚ and 12) being a substrate with guiacol product indicator‚ and a neutral buffer. The guiacol

Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

Time should be kept constant when the potato strip is put into the solution Hypothesis: The mass of the potato strip will increase in water and dilute concentrations of sucrose depending on the concentration within the cell. When the concentration of the sucrose solution outside the cells of the potato strip will be less‚ the mass of the solution will increase as water molecules from outside will diffuse into the cell (diffusion of water molecules from area
