The process of osmosis and its importance to living organisms Osmosis is the process by which there is a net movement of water through a semi permeable membrane from an area of high water potential to an area of low water potential. Within a cell‚ osmosis has the following effect. If the water potential of the cell is lower than that around the cell water will move across a concentration gradient into the cell. If this is the case‚ the increase in water in the cell‚ may cause the cell to swell

Introduction The Catholic Church has emphasized that the rejection of the RH bill is not about a Roman Catholic verdict but a reflection of the “fundamental ideals and aspirations of the Filipino people” (Sison 2011). The Church’s position is anchored on her disagreement with the proposal ’s anti-life stance and problematic attitudes towards issues that affect religious expression. Christianity insists that artificial birth control methods are offensive to life because these tend to suppress

Chapter 2 Literature Review 2.1 Bamboo 2.1.1 Introduction Bamboo is one of the oldest building materials used by mankind [7]. The bamboo culm‚ or stem‚ has been made into an extended diversity of products ranging from domestic household products to industrial applications. Examples of bamboo products are food containers‚ skewers‚ chopsticks‚ handicrafts‚ toys‚ furniture‚ flooring‚ pulp and paper‚ boats‚ charcoal‚ musical instruments and weapons. In Asia‚ bamboo is quite common for bridges‚ scaffolding

Investigating the Effects of Plant growth within Abstract This experiment was conducted to determine whether or not those plants can grow in low fertilized‚ less sun light and the control group. Each group had there own task of making sure that the plants were always water‚ each plant had the same amount of light on them. When the plants started to evolve each individual plant was measured of the height. Most of the plants grew faster than others but over the period the plants that grew faster

The US Food and Drug Administration (FDA) study could reawaken the debate over the safety of breast implants. Many women claim that leaking silicone-gel has sparked serious illness‚ including chronic autoimmune disease. The FDA team used MRI scans too look at 344 women with

Digestion a. The mouth: salivary alpha enzyme chew food‚ perceive taste‚ moisten food with saliva‚ lubricate food with mucus‚ release starch –digesting (amylase) enzymes‚ initiate swallowing reflex - Enzyme: alpha amylase with cooked starch as substrate – starch digestion enzyme an enzyme that catalyses the breakdown of starch into sugar - The Functions of Saliva - 1. Moistens and lubricates food‚ permitting swallowing 2. Holds taste producing substances in solution and bring them in

Capillaries exchange fluids‚ gasses‚ heat‚ nutrients and wastes to the tissues through diffusion. Capillary walls contain small pores that are selectively permeable allowing only certain molecules to pass in and out. This exchange is controlled by blood pressure through hydrostatic pressure and osmotic pressure. Osmotic pressure is produced by high levels and salts and proteins in the blood. As blood enters the capillary by the arteriole end the blood pressure is higher than the osmotic pressure

Ventilator associated pneumonia (VAP) is a nosocomial infection occurring in hospitalized patients who are mechanically ventilated. These infections are common in ICU settings‚ difficult to diagnose early‚ and unfortunately have a high rate of mortality and morbidity. VAP accounts for almost half of infections in ICU settings‚ up to 28% of mechanically ventilated patients will develop VAP and of these patients the mortality rate is between 20% and 70% (Craven & Steger‚ 1998). A patient that develops

Organisms that aren’t food producers must be food consumers. This method of nutrition is described as heterotrophic (eating others). Consumers include: predators‚ parasites‚ scavengers‚ decomposers and some green plants (e.g. sundews‚ Venus flytrap‚ pitcher plants). The food sources may be all or any of: plants‚ animals‚ fungi or bacteria; either living or dead. The advantages of the heterotrophic method of nutrition are: the food usually contains all the appropriate chemicals needed by
