Abstract: Cell membranes play an important role in regulating what goes in and out of the cell. Diffusion, the process of movement of substances across the cell membrane from higher concentrations to areas of lower concentration, plays an active role in the transport and the regulation through cellular membrane. Sometimes, there are cases when cells are placed in hypotonic solutions and substances will diffuse through the cell membrane too much and will result the cell to hemolysis, causing it to swell and rupture. In this lab, we observed and recorded the time it took for diffusion of a propanol series substance to diffuse through a mixture of ovine blood to the point when hemolysis occurred. It was hypothesized that size and polarity of the molecules of a substance do have an effect on the diffusion rate across the cell membrane and that substances containing the smaller and less polar molecules would have a faster diffusion rate than those molecules that are more polar. This experiment was tested by mixing the ovine blood with the propanol series test solutions (Propanol, Propanediol, and Propanetriol) and then placing the test tubes of the blood and substance mixture in front a slit lamp to observe and then record the time it took to view the wire through the transparent mixture. After the lab was completed, it resulted that Propanol took the shortest amount of time to diffuse through the cellular membrane while Propanetriol took the longest amount of time, leaving Propanediol in the middle of the two. These results occurred as Propanol contained the least amount of hydroxyl groups and was the smallest and least polar. Propanetriol was the most polar of the three substances, containing three hydroxyl groups causing the diffusion to be the slowest. These results occurred because as the molecule in a substance becomes larger and more polar, the longer it takes for that molecule to…
#2 – Construct a rhetorical examination of Grimké’s “Appeal to the Christian Women of the South.” What assumptions does she make about her audience, and how does she attempt to connect with them? How does Grimké answer the question, “Why appeal to women on this subject?” Why appeal specifically to Christian women of the south rather than men, or all people? Does limiting her targeted audience strengthen or weaken the overall impact of her argument? What does she want women to do? Finally, briefly summarize the four instructions she lays out for women.…
Once you start to drink it starts to affect your body immediately, you might be a lightweight if you weigh less, but for heavier people it will take a few more. Approximately 20% of alcohol is absorbed through the stomach. The 80% other percent is absorbed through the small intestine. The way you get drunk is that you liver can only process a one ounce of liquor an hour. If you drink…

While there are those who may be uncomfortable with the idea that worship is a goal in making disciples, the goal of Christian education according to Mitchell is to make a disciple who worships Jesus. Mitchell points out that worship is more than just showing up at church on Sunday morning for an hour of corporate worship. He points out that worship according to John 4:19 -24 goes much deeper than just that time of corporate worship that we often think of as worship. He points out that worship involves the whole person, mind, body and soul. Anderson states that corporate worship is “an action of discipling and discipleship” and a “school for the Lord’s service.”…
Alcohol is a drug found in beer, wine, and liquor that causes intoxication. Alcohol can impair a person’s physical and emotional state. Intoxication is the physical and mental changes produced by drinking alcohol (Friedman, Stine, and Whaten 2242). Some people believe that beer and wine are safer than liquor which leads them to believe that it is okay to drink. The truth is that one 12 ounce bottle of beer or a 5 ounce glass of wine is equal to the amount of alcohol in a 1.5 ounce shot or liquor and can cause the same effects (“Facts About Alcohol”). Short term effects of alcohol include nausea, vomiting, dehydration, coma, death, blackout, memory loss, poor vision, reduced reaction time, and loss of judgement along with self control (Friedman,…

When a person drinks alcohol, the alcohol is absorbed by the stomach, enters the bloodstream, and goes to all the tissues. The effects of alcohol are dependent on a variety of factors, including a person's size, weight, age, and sex, as well as the amount of food consumed before drinking. The disinhibiting effect of alcohol is one of the main reasons it is used in so many social situations. Other effects of moderate alcohol intake include dizziness and talkativeness; the immediate effects of a larger amount of alcohol include slurred speech, disturbed sleep, nausea, and vomiting. Alcohol, even at low doses, significantly impairs the judgment and coordination required to drive a car safely. Low to moderate doses of alcohol can also increase the incidence of a variety of aggressive acts, including domestic violence and child abuse. Hangovers are another possible effect after large amounts of alcohol are consumed; a hangover consists of headache, nausea, thirst, dizziness, and fatigue. Some long term effects of alcohol are liver failure, addiction to alcohol or alcoholism, damage to the brain, damage to the fetus of a pregnant woman, and…
Without Christ, there can be no Christian discipleship. Christ is the teacher, friend, leader, guide, savior and Son of God who is the central part of Christian discipleship. 1 John 5:20 says, “And we know that the Son of God has come and has given us understanding, so that we may know him who is true; and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life.” To be a disciple of Christ, one must acknowledge Jesus as the central part of discipleship.…
Alcoholism is a disease which, in many cases, appears to be a genetically transmitted biochemical defect. However, in other instances, it appears to be caused by overwhelming bombardment of the physiology of the body by repeated episodes of heavy drinking resulting in the incapacity to handle alcohol normally. Psychological and/or social pressures may aggravate the disease. It is characterized by a typical progression of drinking behavior that requires an average of twelve and one-half years of drinking to reach fully developed, overt symptoms and an average of eighteen years to reach the stage of deterioration. It is seen most frequently in those of Eskimo or American Indian descent. Among those of Caucasian descent, the Irish, French and Scandinavians exhibit a far higher incidence than do other European population groups. The disease is further characterized by physical damage in all system of the body, the most serious of which is encountered in the cardiovascular system, the nervous system and the liver. In these three areas the damage may eventually prove fatal.…
Drinking has many serious effects. The most obvious effect is the deterioration of health. Drinking increases the risk of various cancers and heart attack, increases liver problems, high blood pressure, stroke, and reduced fertility. These are some of the numerous harmful effects of regularly drinking above recommended levels. Moreover, drinking is the cause of accidents. A person, who drinks, loses his or her judgment to make quick decisions and also have impaired vision. In some cases, a crash will be a consequent of losing the control to drive. Driving drunk is unsafe to you, and everyone else around you. The final effects of drinking is that…
People have been drinking alcohol for thousands of years, and attitudes about alcohol have fluctuated greatly over the centuries. It has gone from being an accepted form of relaxation to being a tool of the devil and recently it has risen to the number one drug of choice among North American teenagers. Alcohol is classified as a drug because of its effects on the body. It is not digested like a food; instead it is absorbed directly into the bloodstream and travels to the brain. Alcohol first acts as a stimulant by making the drinker feel happy and less inhibited because alcohol affects the part of the brain responsible for learned behaviors, like self-control. As more alcohol enters the bloodstream and saturates the brain, it starts to act as a depressant on the central nervous system. This results in slurred speech, loss of co-ordination and possibly a drop in level of consciousness.…
When a person is intoxicated with alcohol he/she will not have a normal metabolism. Alcohol has a biphasic effect on the body, which is to say that its effects change over time. Initially, alcohol generally produces feelings of relaxation and cheerfulness, but further consumption can lead to blurred vision and coordination problems.…
