In this lab we will look at how molecules move across the membrane of a cell . Osmosis is the movement of water across a cell membrane.In osmosis the cell membrane is selectively permeable‚which allows for the membrane to control what types of substances that passes through.Transportation can either be passive or active.Passive transport does not require the use of added energy where as active transport requires the cell to use energy. Diffusion is the simplest form of passive transport. Using

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

Chris Wiginton IS-3120 Unit 6 Assignment 6 Cisco-Layer 2 Resiliency Compared to HP’s IRF In order to provide speed and reliability‚ large and enterprise-level networks today are typically constructed in multiple layers. They are the access layer‚ also called the network edge layer‚ the aggregation or distribution layer; and the network core layer. The access layer is usually a mesh of network switches‚ linked to other switches in the aggregation layer‚ which in turn is linked to the core. This mesh

Stuart Mill‚ author of the chapter “Of the Liberty of Thought and Discussion” in the philosophical work On Liberty‚ outlines four main arguments of why society is impacted by the silencing of others’ opinions. Wayne Fuller‚ author of the chapter “Diffusion of Knowledge” in the work The American Mail: Englarger of the Common Life‚” presents ideas that Mill would be able to apply his ideas to. Mill’s first argument is that suppressed opinion has the possibility of being true‚ which is why no idea can

The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

type of diffusion called osmosis‚ “which involves in selective transport of water molecules across a selectively permeable membrane” (Lab Manual 2nd edition). It was hypothesized that osmosis will occur when there is an uneven distribution of solute in a solvent. The more abundant the solute is in solvent‚ the higher the rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Throughout this lab‚ data was

Diffusion of Hydrochloric Acid into Different Sizes of Agar Blocks Aim: Investigating the relationship between the diffusion and the surface area to volume ratio‚ with agar and hydrochloric acid. Research Question: How does the difference in surface area to volume ratio affect the diffusion? Hypothesis: As the area to volume ratio increases‚ the time taken for a complete diffusion will also increase. Background Information: Agar is a jelly like substance and in this experiment‚ agar

Although Christianity and Buddhism both flourished through social interaction over the silk roads‚ which lead to immense cultural exchange‚ there were various reasons linked to religious diffusion which were greatly taken advantage of with respect to regional and religious distinctions. Starting in 200 BCE and developing well into 700 CE‚ the silk roads and sea routes spanned across most of Asia‚ linking the Roman Empire with China and other
