The alternative hypotheses in this case is dropping an atomic bomb against your enemies will end war and save lives. The null hypothesis was ending war and saving lives had nothing to do with the reason why the atomic bomb was dropped. It was dropped on the sole propose of showing the world that it would be willing to use nuclear weapons against its enemies. Finding the data on how many times we used bombs on enemies and non-enemies can test both hypotheses. After that we will take a look at the

Question- Does adding peat moss to sand affect its ability to hold water? Hypothesis- If I add peat to sand‚ then the peat moss will hold most of the water because the peat moss can hold large amounts of water. Variables- Manipulated Variable- adding peat moss to sand Responding Variable- peat moss can hold most of the water amount Levels- 100% sand‚ 60% sand/40% peat moss‚ 40% sand/60% peat moss‚ 80% sand/ 20% peat moss Trials- 5 Constants- same amount of water‚ same kind of containers‚ same sand

Brownian motion This is‚ presumably the random drifting of particles suspended in a fluid (a liquid or a gas) .This movement was discovered and later named after botanist Robert Brown (1773-1858). He was a Scottish botanist and palaeobotanist who made important contributions (including Brownian motion) to botany largely through his pioneering use of the microscope. The scientist who made Brownian motion famous is Albert Einstein‚ who brought the phenomenon to the attention of the larger physics community

oxygen bubbles generated by an elodea stem tend to not be “student” proof or reliable. This is a particular problem if your laboratory instruction emphasizes student-generated questions. Over the years‚ I have found the floating leaf disk assay technique to be reliable and understandable to students. Once the students are familiar with the technique they can readily design experiments to answer their own questions about photosynthesis. The biology behind the prodedure: Leaf disks float‚ normally.

However‚ the solutes are too big to pass the cell membranes without the help of channel proteins‚ or transport proteins. Water may freely pass through the membrane by osmosis‚ which requires no energy. Thus‚ the cell starts to take in‚ or release‚ water until it is isotionic to its
Premium Osmosis Concentration Chemistry
Osmosis is the diffusion of water molecules from an area of high concentration of sucrose solution to an area of lower concentration of sucrose solution‚ through a selectively permeable membrane. The water molecules move down a concentration gradient in osmosis. Two diagrams of osmosis are shown in figures 1 and 2. Figure 1 shows the diffusion of water molecules through a selectively permeable membrane from an area of highly concentrated sucrose solution to an area of lower concentrated sucrose solution

Many psychologists agree that the free expression of the physical characteristics of emotions‚ such as smiling or frowning‚ are actually direct feedback of the emotion an individual is feeling. For example‚ a smile from a person may cause
