(heritable) traits in different organisms over time. If you’re thinking apes becoming humans you’re already wrong. There’s even evidence of evolution like fossils‚ DNA samples‚ similarities in bone structure‚ and even vestigial organs. The purpose of this lab is to see how evolution works and whether it is a reliable theory. Hypothesis: If there are 11 skulls that all have different structures 4 of them will be bipedal. Independent variable: Is all the measurements of each skull Dependent

Problem What effect does the different concentration of hydrochloric acid have to the rate of diffusion of agar that is dissolved with sodium carbonate and phenolphthalein? Introduction Diffusion is a process where the molecules intermingle as a result of their kinetic energy of random motion and is the net movement of like molecules down their concentration gradient‚ which is the energy inherent in their constant molecular motion makes them collide and careen outward from the region of higher

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

LAB 1 Background and Hypothesis: I know I haven’t passed the lab 1 H and B but I really do not want to lose points again just for the fact I didn’t get it done in time. I already lost -5 pts and I really don’t want to lose -20 pts. So I am just gonna go on a whim here and just get it done through here so it doesn’t automatically fail me without me at least trying. Background: Test to see if people who are Left Handed would be left thumb dominant and compare to see people who are Right Handed

The refraction of light lab used common materials to examine the process of the refraction of light. The title of this lab is exactly what occurs throughout the four different experiments. All four parts of this lab use prior knowledge to observe the complex concept of refraction. Refraction is the bending of a light when it enters a medium where the speed of light is different. When light enters through the glass and water the speed of light becomes decreased. This is due to the density of water

Lab Report: Scientific Method Your Name: Alyssa Melincoff Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? To find out how table salt affects the boiling temperature of water. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding
