Distilled water is a hypotonic solution which means in contains no solutes. According to the text (p.72), â€Å"Cells placed in a hypotonic solution plump up rapidly as water rushes into them.† This means that a RBC would eventually pop. C. Create a graph of your experimental data by plotting the percent change in potato mass against sucrose molarity. Label the x-axis as â€Å"Molarity of Sucrose,† and the y-axis as â€Å"% Change in Mass.† D. Determine the molar concentration of the sucrose contained in the potato strips by using the graph created in question C. At the point where the molar concentration of the sucrose in the potato would be isotonic to the sucrose, there would be no net change in the potato mass. On the graph, this is located at the 0% change. Draw a line from this place on the y-axis to intersect the line. From the line draw a line down to the x-axis to find the molarity. Molar concentration of sucrose in potato = .3 M Exercise 3: The Effect of Solvents on Membrane System Observations Data Table 3: Color Intensity from Damaged Beet Cells | TestTube | Solution Treatment | ColorIntensity0 – 10 | Condition of Beet (turgid, flaccid, etc.) | a | 70% Isopropyl alcohol | 10 | Very flacid | b | 35% Isopropyl alcohol | 7 | bendable | c | 17.5% Isopropyl alcohol | 3 | Less firm | d | Distilled Water | 0 | VeryShow MoreRelatedEssay about Cell Membranes and Transport1350 Words   |  6 PagesCell Membranes and Transport Hands-On Labs, Inc.

How Can A Model Be Created?987 Words   |  4 Pagesa model be created to simulate cell membranes and permeability? Background: The Plasma membrane is mainly composed up of phospholipids and proteins. The cell membrane determines which molecules can diffuse through the cell. This characteristic of a cell membrane is called selective permeability.

While examining this lung tissue Gram discovered that certain stains were more favorable and retained by the bacterial cells. It was only a few years later that Gram produced a staining procedure that he divided into two groups. The two groups divided almost all bacteria into what he called Gram positive (purple) and Gram negative (pink). The Gram’s staining procedure is still used today and is the method that forms the basis for identifying bacteria.

Beyond that, diffusion can further be divided into two different kinds of net movement of substance to opposing concentration gradients, dialysis and osmosis. Dialysis is defined as the separation of small molecules from large molecules as they pass through a semipermeable membrane (Koerner, 1992). When talking

Exegesis of Ephesians 21-7 - 3183 Words

God’s Mercy for the Ephesian Church: A Look at Ephesians 2:1-7 INTRODUCTION The book of Ephesians is one of Paul’s many New Testament letters, or epistles, to the Christian church still in its infancy. At the time of its writing, Paul is in Rome, imprisoned for championing the purposes of Christ and growing the church. We see numerous occurrences where Paul, being a man of little concern for the status quo, is either imprisoned or fleeing capture by Jewish or Roman officials for usurping the latter (Acts 19: 23-41). The date of Paul’s letter to the Ephesians is dated 60-61A.D., depending on differing research. While this is certainly one of his epistles known as the â€Å"prison letters†, Ephesians was penned prior to Paul’s first roman†¦show more content†¦Despite increasing displeasure with Nero, that Roman wealth spread to the major cities of its empire including Ephesus. Therefore, Paul, employing the Lords wisdom, ensured the church to be viable and Godly in a city mentioned of similar importance as Rome, Corint h, Antioch, and Alexandria. In his ministry, Paul makes multiple journeys to Ephesus to ensure that the Word was growing in such a keystone city to much of eastern Asia. On his first missionary journey, he diverted to Macedonia at the Lord’s prompting, prohibiting him from travelling to the region. However, Paul leaves behind Aquilla and Pricilla (Acts 18:18-21), on his second journey, as more of an advance party to begin establishing the church. This was a necessary move, as a full effort by Paul to minister in Ephesus would have not gone successfully. The Ephesian economy aligned itself with pagan religion, as well as Judaism, and relied heavily upon trades, such as idol making, which related to the worship of pagan gods. For example, the temple of Artemis sustained an industry of silversmiths and idol makers. During Paul’s second third journey, due to his effective ministry in Ephesus, caused such a disruption in pagan commerce, merchants incited a mob to eli minate him from the city. The church remained despite his hasty departure. Paul centered his basis of ministry in this keystone city during his third missionary journey. As a result, this allowed him toShow MoreRelatedExegesis on Ephesians 6:1-31445 Words   |  6 PagesEXEGESIS PAPER ON EPHESIANS 6:1-3 ‘Children Obeying Honouring their parents is a right thing to do and bring blessings’ Background: Paul the author of this letter, realizing that the Ephesians were starting to forsake their first love, wrote this epistle to encourage them to love both God and their fellow saints. The letter begins with love (1:4,6) and ends with love (6:23-24).1 Chapter 1-3 are principally the doctrinal elaboration of the theme, love, unity, and chapter 4-6 teach what shouldRead MoreTechniques and Assumptions in Jewish Exegesis2168 Words   |  9 PagesIntroduction Hillel is remembered not for his inspired exegesis but for his rationalistic exegetical techniques, (Brewer 219). These rational exegetical techniques have been codified into the Seven Rules of Hillel, which many claim predate Hillel himself (The Seven Rules of Hillel). Regardless of when, how, and with whom the Seven Rules of rabbinical exegesis emerged, it is clear that Paul relied on these rules when conveying the teachings of Jesus Christ to the Jews. As Cohn-Sherbok pointsRead MoreThe Ephesians, One Of Great Intriguing Distinction Essay1937 Words   |  8 PagesThe Epistle of Paul to the Ephesians is one of great intriguing distinction. The letter possesses unique properties in comparison its fellow Prison Epistles namely, Philemon, Philippians and Colossians. The author of this work seeks to further expound upon these unique properties and its implications for how one should interpret the Epistle, specifically Ephesians 1:3-14. Authorship It has been generally accepted that the Apostle Paul is the Author of the Epistle. The Early Church Leaders acknowledgedRead MoreThe Workings Of Christ1197 Words   |  5 PagesIn all of Paul’s writings an array of words are expressed to describe the workings of Christ. In many of these cases thorough exegesis is necessary to understand the true content and application for daily life. One of the heaviest of these words that has caused a large amount of debate throughout history, and one that is imbedded in the book of Galatians, is justification. Nonetheless, the means that individuals receive this form of justice is through faith, and faith alone according to Paul.

He is working to fulfill God s plans that has been in place before the foundation of the world. God’s plan as the Apostle Paul says is to redeem his people in Ephesians 1:6-7.

After the exile of the Israelites in Babylon and their subsequent return to Israel, there was a need for interpreting the Pentateuch. Most of the Israelites in Babylon probably lost their ability to read and understand Hebrew. We see evidence of this in Nehemiah 8:8 as the Israelites implore Ezra to read to them. This event signaled the beginning of the science and art of biblical interpretation.

This proves to be the case in Philippians 2:19-24. In these six verses Paul is intending to communicate two main points: (1) He believes that Timothy is a respectable teacher of God’s word, and he wants the Philippian congregation to recognize this (Phil 2:22); (2) Paul intends for Timothy’s visit to be encouraging to the Philippian brethren, and for their encouragement to be reciprocated in himself.Read MoreCommon Ground Between Muslim And Christian Belief Essay2041 Words   |  9 Pagesuseful for spiritual development (2 Timothy 3:16-17).
