Isotonic

trends for % change in mass and increasing molarity. Therefore, if these two values are removed and a linear equation is used (figure 5), the x-intercept (where the % change in mass is zero) is the estimated value of the molarity where the solution is isotonic to the potato, around 0.229M. The osmolarity of the potato can then be deduced by multiplying the molarity by 2, as there are two particles (Na+ and Cl- in the solution for each compound of NaCl); thus, the osmolarity of the potato is…

Water a vital biological molecule Molecule of water Water is a substance which is transparent, odourless and colourless liquid that has a boiling temperature of 373K, freezing temperature of 273K meaning it is liquid at room temperature. Water is a compound containing 2 hydrogen atoms, but also has an oxygen molecule as well this means it has the molecular formula of H2O. The relative atomic mass of water is around 18 with “11.188% being hydrogen and 88.182% being oxygen” [1]. When bonded it…

they need to use contractile vacuoles to get rid of excess water in the cell, enabling it to osmoregulate. Compare the ideal osmotic environment for animal cells and plant cells The ideal osmotic environment for animal cells would be if it were isotonic, meaning the cell and the environment have the same concentration of solutes and water, so the cell won’t change. The ideal osmotic environment for plant cells would be if it were hypotonic, meaning the environment has a lower concentration of…

Guillain Barre Syndrome Guillain Barre Syndrome (GBS) is an autoimmune disease affects the peripheral nervous system. The defining symptom of this syndrome is the body is attacking itself. GBS does affect both males and female of any age but most common seem to be between the ages 30 to 50 years old. A variety of symptoms can occur depending on the severity of the disease. Since this is a very aggressive disease, early and quick diagnosing is essential to the recovery of the patient. Physicians…

Colloids and Crystalloids on fluid resuscitation during hypovolemic shock John Tristan Pahuyo, Staff Nurse ACCU-Barts Heart Centre Hypovolemia is generally defined as having a significant amount of blood volume loss. Shock, on the other hand, is a medical emergency characterized by inadequate blood flow to organs and tissues thus reducing oxygen delivery that leads to organ dysfunction. Hypovolemic shock is described as a loss of greater than 15% of the intravascular volume. It is caused by an…

not get the relationship between the length of the muscle and the tension produced. Like for isometric, the length of muscle remains the same while not enough tension is produced for the movement, that means there is a strain on the muscles? For isotonic, the muscles length changes but the tension remains constant. I do not quite get that. 3. In the exams, when they ask us to identify the positions like lateral, medial, proximal etc, and say it is not according to SAP, do I follow the…

The case is about a 22-year-old female who has been sick for eight days. She thought that she had the “Flu”. She complained of nausea, vomiting and had a poor appetite. To counteract her nausea, she was taking copious amounts of antacids. She fell at home and was taken to the ER. She was dehydrated and intravenous fluids were given to rehydrate her. An arterial blood gas (ABG) was drawn. The results of the ABG showed an acid-base disturbance. The patient’s acid-base disturbance was acute…

remains constant, the dialysis tubing will deflate over the course of the allotted time, because the process of osmosis leads the flow of water from low concentration of solutes to the high concentration of solutes in order to create a balanced, or isotonic,…

Harvey, Brittani. Goodman, Dana. Honts, Alyssa . Lambert, Carlie. Drei, Ryan. A&P Lab: Section 3 8 June , 2018 Case Study Q1:What sort of environment (hypertonic, isotonic, hypotonic) does consuming excessive amounts of pure water create in the body fluid that surrounds your cells? What effect would this have on your cells? A1: Consuming too much water would cause your cells to become hypotonic. The cells would experience a higher than normal percentage of H2O and consequently have a smaller…

1 Beaker—600 mL 1 Plastic Cup---500 mL 400 mL of White Vinegar Tap Water 400 mL of Corn Syrup Graduated Cylinder---500 mL Raw Egg in Shell Ruler Masking Tape Permanent Marker Paper Towels Procedure 1)Look at the raw egg, and study the appearance of the eggshell. 2)Take measurements of its mass and circumference. Record your information in a data table. 3)Use a graduated cylinder to measure 400mL of vinegar. Pour the vinegar into your cup. 4)Place the raw egg into the cup with…
