Premature Rupture of Membranes Article Review As the article states‚ premature rupture of membranes occurs when the amniotic membranes surrounding the growing fetus rupture causing a loss of fluid before 37 weeks of gestation and before the onset of natural labor. PPROM‚ preterm premature rupture of membranes is seen often in women who smoke and use recreational drugs. If PPROM occurs before 26 weeks of gestation it is considered extreme and more often than not leads to more serious complications

To investigate the effect of variation in temperature on the permeability of cell membranes using fresh beetroot Aims In this investigation‚ you will subject fresh‚ washed beetroot discs to different temperatures to investigate the effect of temperature on the permeability of the plasma membrane. Overview The beetroot discs will be placed in distilled water at different temperatures. You will compare the intensity of the beetroot pigment that has leaked out from the cells subjectively and possibly

Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

People who decide to become medical doctors need to make several sacrifices. The training to become a doctor is long and difficult. Furthermore‚ it does not end with school because doctors are required to learn about new problems and advances in the field of medical science for the rest of their lives. However‚ there is a positive side in becoming a doctor. It is not just about learning complicated procedures and going through rigorous training. Being a doctor means that a person is required to nurture

This book is a nonfiction academic monograph. Since she discusses other people’s research‚ she synthesizes other research works. She discusses more than she presents -- it is not a dry list of data throughout the book. Motive of author: Radden has a desire to compare what lies behind the differences in people’s behaviors (the way we process and see things). There are all different kinds of delusions. She wants to explore the social implications and domains of research of delusions. There are

difference in the osmolarity‚ no change in the cells sizes. PART 3 Procedure: 1. Repeat step (1 – 3 of PART 2) using 30% of sucrose solution. Results & Observations: In the hypertonic solution we can notice the shrinking of the cell membrane due to the loose of water. Discussion & Conclusion: Water will move in or out of the onion cells according to the concentration of sucrose in and out of the onion cells: in an isotonic solution no change will happen; in a hypertonic solution
