Simple Diffusion Activity 1: Simulating Simple diffusion 1.What is the molecular weight of Na+? 22.9 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because the molecular weight exceeded the highest MWCO membrane‚ thus being to large to pass through

1. Human beings are made in the image and likeness of God‚ and therefore are given a great deal of dignity. To properly understand who we are‚ we need to go back to the beginning. In the beginning‚ God made us like Him. Genesis 1:27 says: God created man in his image; in the divine image he created him; male and female he created them. We were created to be a lot more than what most people settle for. For God did not call us to impurity but to holiness. (1 Thessalonians 4:7.) If you’ve ever

Biology Lab #1: Chemical Diffusion Purpose To discover how the size of a cell affects the diffusion of chemicals throughout the cell. Hypothesis I predict that as the cell size increases the diffusion depth and the diffusion rate will decrease. Equipment • Eye protection • 250 mL beaker • Timing device • Scoopula • Ruler • Scalpel • Sodium hydroxide solution • 3 different sized cubes of phenolphthalein agar • Paper towels Purpose

There are many different worldviews but my world view is Christian worldview and my personal thoughts and beliefs on God and Worldview I feel to be very strong. What is a worldview? “A worldview is a set of beliefs about reality and human nature.” (Cosgrove. M.P.‚ 2006; p.18) I see many people in our society being viewed and discriminated due to those beliefs. I find this dishearten. My worldview has taught me to treat others the way I would want to be treated. Reality‚ Human Value‚ Ethics‚

This means that the doctrine of scripture can be taken as the lessons and teachings we take from scripture itself. But why is it that we use these doctrines as Christians‚ why is it that we take these words to heart? All scripture is inspired by God. “Inspired means‚ literally ‘God-breathed’” (Stewart). This means that the doctrine of scripture is the word of God written through somebody else. The scripture

Lab # 2 Diffusion & Osmosis Introduction Kinetic energy‚ a root of energy stored in cells‚ causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water

worldviews are breaking out everywhere especially throughout North America. Two sides with vastly differing and incompatible worldviews are being locked in a bitter conflict that permeates every level of society. On one side of the battle is the Christian worldview‚ and on the other is the Humanist worldview divided into three branches: Secular Humanism‚ Marxism/Leninism‚ and Cosmic Humanism. It’s in this essay that we will seek to understand all of the three Humanist worldviews while presenting a

The authority of Scripture is a key issue for the Christian Church in this and every age. Those who profess faith in Jesus Christ as Lord and Savior are called to show the reality of their discipleship by humbly and faithfully obeying God’s written Word. To stray from Scripture in faith or conduct is disloyalty to our Master. Recognition of the total truth and trustworthiness of Holy Scripture is essential to a full grasp and adequate confession of its authority. The following Statement affirms

The purpose of this lab was to observe the rate of osmosis and diffusion‚ as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion‚ that dealt with raisins in different liquid environments‚ each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration‚ by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases‚ the

The idiom “there are plenty of fish in the sea” is not literally true. In fact‚ the documentary‚ The End of the Line‚ has estimated that by approximately 2050‚ there will be no fish in the sea. Overfishing is a serious issue that involves taking wildlife at increasingly higher rates than the species can replace. Because this issue is hidden under waters‚ people do not realize the seriousness nor do they realize the consequences. This film highlights some of the well-known species‚ such as bluefin
