Based on the result‚ what is known now is when osmolarity is low‚ the hemolysis is high; while when osmolarity is high‚ the hemolysis is low. This supports the hypothesis if the erythrocytes were placed into a high osmotic solution‚ then the erythrocytes would have a lower hemolysis percentage. As shown in graph 1‚ when the erythrocytes were placed into the tube containing 250 to 390 osmolarity of solution‚ the erythrocytes results in below 26 hemolysis percentage. When the erythrocytes were placed

STUDY QUESTIONS FOR TEST 3 (Major concepts)—CHAPTERS 5‚ 6‚ 7 This study guide does not include everything you need to know for the exam. It an overview of main topics that I thought were important in lecture—make sure you’ve studied your book‚ completed the questions at the end of each chapter‚ answered all of the study guide questions‚ and taken the practice exam a few times! I would recommend either writing out the answers or‚ if you’re studying with someone else‚ talk through these questions.

Active transport: membrane proteins use cellular energy (usually ATP) to move molecules or ions across a plasma membrane against their concentration gradient. Allele: different forms of a gene • genotype – the combination of alleles in an organism. Aquaporin: a specialised channel protein in the plasma membrane of a cell‚ which is selectively permeable to water. Attachment protein: a protein in the plasma membrane of a cell that attaches either to the cytoskeleton inside the cell‚ to other cells or

Ovarian cancer can develop from the epithelial cells surrounding the ovary‚ the germ cells‚ or stromal cells within it. Epithelial ovarian carcinomas account for 85-90% of ovarian cancers‚ and will be the focus of this essay. Most symptoms of epithelial ovarian cancer are due to the fact that it often spreads to the lining of and organs in the abdominal cavity. These symptoms include bloating‚ pelvic or abdominal pain‚ urinary urgency or frequency‚ and trouble eating associated with feeling of fullness

Blood Water Homeostasis or Osmoregulation Osmoregulation is the process by which the body regulated the osmotic pressure of any organism’s fluids in order to keep the homeostasis of the organisms’ water level constant. Therefore osmoregulation is used to keep the bodily fluid from being too diluted or too concentrated. An osmotic pressure is used to measure the ability of water to move from one solution to another solution through osmosis. Osmotic pressure refers to tendency for a liquid solution
