INTRODUCTION Tissue paper has been a significant part of our day to day life for the purpose of purity‚ cleanness and freshness. Facial tissue and toilet tissue has been the most widely used form of tissue paper. Facial tissue refers to a class of soft‚ absorbent‚ disposable paper that is suitable for use on the face. The term is commonly used to refer to the type of facial tissue‚ usually sold in boxes‚ that is designed to facilitate the expulsion of nasal mucus from the nose although it may refer

PHYSIO EX 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. The temperature of the solutions and the difference in concentration of the ion or molecule between the sides of the membrane 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? Since the chemical formula for urea is (NH2)2CO and its molecular weight is about 60. It will not diffuse through the

Activity 1 Pre-Lab Quiz K+ inside a cell = 150 mM; K+ outside a cell = 5 mM Na+ inside a cell = 5 mM; Na+ outside a cell = 150 mM Stop & Think question What is the polarity of the resting membrane potential (voltage)? Negative What does it mean that the voltage just inside the membrane is negative? B Membrane of most cells contains K+ leak channels…..b What will happen to the resting membrane potential if the extracellular K+ concentration is increase? Less negative What happens

NAME LAB TIME/DATE _ Endocrine System Physiology: Computer Simulation Metabolism The following questions refer to Activity 1: Determining Baseline Metabolic Rates. 1. Which rat had the fastest baseline metabolic rate? -------------------------The normal rat 2. Compare the baseline metabolic rates for the thyroidectomized rat and the normal rat and explain your results. The thyroidectomized rat had a lower baseline metabolic rate beause the removal of its thyroid gland prevented it

Tissue Expanders A tissue expander is a device that is made from elastic silicone rubber. During the mastectomy‚ this balloon-like device is placed after the surgeon removes skin and tissue to allow for placement of the tissue expander beneath the remaining muscle and skin of the patient’s chest. The tissue expanders are inserted either empty or with a minute amount of saline in them. As time passes‚ sterile saline fluid is added to the expanders: This is accomplished by inserting a small needle

contrast xylem tissue and phloem tissue‚ including their respective structures and functions. The stems and roots of plants contain two separate transport systems; xylem vessels and phloem tubes‚ of which neither transport oxygen as it is transported to cells by diffusion. The network of xylem vessels transports water and mineral ions from the roots to all other parts of the plant whereas phloem tubes transport food made in the leaves to all other parts of the plant. In the stems the tissue is collectively
