• Discussion: The results acquired from the experiment have supported the hypothesis. In the first sample, red blood cell in the isotonic solution (NaCl 0.85%) kept its regular shape. This is because when RBC was placed in an isotonic solution, which is the solution has the same concentration of solutes as the cell, water will move into and out of the cell simultaneously and no net effect will be seen. In the second sample, cell shrank, and crenation occurred in the hypertonic solution (NaCl 10%) because the hypotonic solution has a higher osmosis pressure than the cell, water is going to escape from the cell for decreasing the high concentration of solute in the hypotonic solution. Lastly, in the hypertonic solution (NaCl 10%), cell bloated,
and hemolysis occurred because the hypotonic solution has a lower solute concentration than inside of the cell. This causes water molecules move from the outside solution into the cell in order to stabilize the concentration of solute and put a lot of pressure on the cell. • Clinical Implications: Based on the characteristics of red blood cells and osmosis, many clinical settings were used. For example, hypertonic salt solutions (3% saline) have been used as an effective way for treating hyponatremia. When patient’s blood stream has become hypotonic and it’s supposed to be isotonic, adding a hypertonic solution will increase the electrolyte imbalance back to normal levels. Another example is using hypotonic solution for a patient who has been on diuratic therapy, his/her skin and mucous membrane are dry. Adding hypotonic solution will help the skin and mucous membrane become more hydrated than isotonic and hypertonic solution.
In the article, Blood Red Night, author Lauren Tarshis' point of view is focused mostly on the destruction that the fire caused. I know this because most of the ideas that she conveys in the text use words that have to do with destruction. For example, in the section "A Choking Fog", the author states, "The blazes burned hundreds of acres of forestland and incinerated hundreds of homes and shops in nearby communities." This sentence uses several words such as blazes and incinerated which illustrate for the reader the destruction that happened during the peshtigo fire. Another example of when the author mentions the destruction that the Peshtigo fire caused was in the section "Sheets of Flame" when she states, "By morning, more than a billion
Dialysis tubing is made from regenerated cellulose or cellophane, and is used in clinical circumstances to ensure that molecule have a filtered flow, and that larger solute molecules do not enter the dialysis tubing (Alberts, 2002). Like a cell membrane, dialysis tubing has a semi-permeable membrane, which allows small molecule to permeate through the membrane. Thus, the dialysis tubing mimics the diffusion and osmosis processes of the cell membrane (Alberts, 2002). Although the dialysis tubing has a semi-permeable membrane, which mimics a cell, its structure is different. The me...

Racism, a plague in our society that has infected our society, and still does today, has been rooted by the premise of Darwinian evolution. Racism existed long before Charles Darwin made his mark in history; however, in the book One Race One Blood, the authors explain how there is a very close relationship between the theory of evolution and what we know today as racism. The authors intent of this book is to realize the effects of a specific ideas that has shaped racism. Mr. Ken Ham describes ideas as being seeds, “…they might seem small; they might seem insignificant; they might even go unnoticed by all expect those who hold them in the moment…” (7). Charles Darwin’s idea (or seeds) of his evolutionary has taken root and made its way into public schools, the government, and even our churches. Although, racism did not originate with Darwin, Ken Ham claims that, “he did more than any other person to popularize it” (22). His evolutionary ideas have fueled racism and this is what racists use to justify their hatred toward those who are different from them (8).
The largest component of the blood is the Plasma, a liquid substance made up of 91.5% water and 8.5% solutes that is responsible for over half the blood’s total volume. This liquid portion of the blood is vital for maintaining blood pressure within the body that helps capillary exchange. (Tortura 691-692). Cases of hemorrhagic or hypovolemic shock, a severe reduction in plasma is what triggers the body’s feedback systems, and compensation for fluid loss will stem from pulling of water from other
The pump is sensitive to the potassium concentration of the blood. When extracellular potassium increases the pump increases in activity and more potassium is taken up by the cell, when plasma concentration is low the reverse occurs. [5]
The purpose of this experiment is to investigate the effect of changing the concentration of sodium chloride solution on the rate of osmosis in tubes of potatoes. This was maintained using equal measurements of the potato tubes and applying them into the different concentrations of sodium chloride, 0%, 2%, 5%, 10%, 20% and 26%, in beakers then measuring the change in mass of the potato tubes afterwards. The time taken for all potato tubes to be placed in solution was 15 minutes. Can the concentration gradient of the sodium chloride solution influence on the rate of osmotic diffusion undergone by the potato tubes?

Another trend in this table which demonstrates this phenomenon is the decreasing FPV of the CHO cells after cooling and freezing/thawing which shows the increasing membrane fluidity. However, compared to the control cells (at 0 mg) the CLC treated cells still showed considerably less membrane fluidity after being cooled.

In Blood In Blood Out is a drama directed by Taylor Hackford, and starring Damian Chapa (Miklo), Benjamin Bratt (Paco), and Jesse Borrego (Cruz), produced by Hollywood Pictures. The film was based off everyday life in East Los Angeles, from the 1970’s through the 1980’s. Damian Chapa stars as Miklo in the film, a Mexican-American who wanted to be accepted, not by his skin but for the Mexican within him. Benjamin Bratt (Paco) was the older cousin of Miklo, who learned his lesson throughout the movie and changed his ways. Jesse Borrego (Cruz) is the step-brother of Paco who was a talent artist, who ended up turning to drugs because of back problems caused by a rival gang incident.
Bacteria exist everywhere in the environment and have continuous access to the body through the mouth, nose and pores of skin. Further more, many cells age and die daily and their remains must be removed, this is where the white blood cell plays its role.

Bufffers play an important role in many biological processes as the majority of them are affected by pH. The pH fluids residing inside and out of cells (intracellular and extracellular) is maintained through buffer systems One example of buffer that plays an important role as a buffer in maintaining the pH of blood is bicarbonate.

Further 15% cleans the cells interstitial liquid (fluid) and is then and there relocated into the lymphatic system for final return to its original place which is the blood.
