Michelle Yeung Bio 101 Cyrus MacFoy June 16‚2015 Diffusion and Osmosis Exercise I. Molecules are always in constant movement. Molecular motion is a form of energy‚ the kinetic energy of molecules. The Brownian movement is the movement of small particles caused by the bombardment of the particles by millions of water molecule. This movement will continue indefinitely as long as there is water. My prediction for this lab is the solution of the water is hypertonic meaning there is a higher concentration

merchants‚ and at the bottom the slaves and peasants. They both had their own form of writing; Mesopotamia had cuneiform‚ and Egypt had hieroglyphics and cursive script‚ respectively. While they are similar in many different political‚ social‚ and cultural activities and ideas‚ they have enough contrast to be viewed as different societies. Politically‚ because they were geographically open to envision‚ Mesopotamia culture created compact self-governing political units- the city-states. By the third millennium

1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer

Similar to the civilizations of Mesopotamia and Egypt‚ early civilizations that arose in India surrounded river valleys (pg.38). Since these civilizations arose‚ the geography of the land played a key role in the development of these civilizations. The land provided the civilizations with the perfect diversity of geographic features. This subcontinent is composed of multiple regions that are key to civilizations. First‚ “in the far north are the Himalayan and Karakoram mountain ranges‚ home of the

Mesopotamian Civilization Mesopotamia was located between two rivers the Tigris river and the Euphrates river. The rivers were very helpful to them. The rivers gave them water and a way to travel. Between the two rivers was very fertile soil‚ which helped them‚ farm near their homes. They also had a semiarid climate‚ which is it rains a lot and the summers are very hot. The first civilization was Sumer and they believed in polytheism or the belief in many gods or goddess. They believed

Dependent variable: We are measuring the time taken for the pink indicator to turn clear when hydrochloric acid is added to it. Independent variable: We are changing the molar of hydrochloric acid we are adding to the gelatine cubes. Apparatus: * 1 measuring cylinder * 1 test tube * 1 stop clock * A large gelatine

Our world today wasn’t entirely created from recent achievements. We have collected knowledge from ancient civilizations such as Mesopotamia and Greece by studying their history and improving their accomplishments. These cultures have had a major impact on the daily lives of the people in the modern world. Although Ancient Mesopotamia and Greece were some of the earliest civilized cultures‚ they differ greatly in their achievements and innovations that played important roles for future humans.

turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable to starch. 4B- The hypothesis was supported because the diffusion rate was faster shown from the agar blocks. The materials passed through the membrane easily and quickly in the small cells than the large‚ making them more efficient. The smaller the cell is‚ the faster it can transport signals. The bigger cell

Known as one of the earliest civilizations‚ Mesopotamia and Egypt both share set amounts of similarities along with a share of striking distinctions. Environmentally‚ these two civilizations were formed in similar surroundings‚ yet their weather patterns show distinctions. Politically‚ both governments derived from a monarch‚ yet their laws and punishments distinguished the two’s court systems. Economically‚ they both shared prosperous success in similar manners. Socially‚ although the two lands

influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that can affect the rate of this diffusion. Our intent was to measure
