fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. Fatty acids Fatty

Water Transport in Plants Introduction In this lab experiment‚ we set out to examine the different transpiration rates of a plant system in certain environments. Water is transported in a plant by the process of transpiration‚ which is the loss of water through evaporation from the surface of leaves. The stomata in leaves are responsible for the diffusion of water vapor. Transpiration brings water upward through the xylem in the plant. There are certain factors that can affect transpiration

Exercise is a healthy approach to life‚ a hobby in varied forms‚ a must for a physically fit lifestyle‚ but also a necessity for a sharp mind and emotional stability? Physical activity promotes not only what the eyes see‚ but also what is felt inside. School‚ health administrators‚ and even mothers have preached the importance of exercise to our body. However‚ the real benefit is reaped through the most complex organ‚ the brain. With an organ that’s constantly at work‚ exercise increases the executive

Exercise for Diabetics Diabetes is a group of metabolic diseases in which a person has high blood sugar‚ either because the body does not produce enough insulin‚ or because cells do not respond to the insulin that is produced. This high blood sugar produces the classical symptoms of polyuria (frequent urination)‚ polydipsia (increased thirst)‚ and polyphagia (increased hunger). There are three main types of diabetes mellitus (DM). Type 1 DM results from the body’s failure to produce insulin

are important to understanding cell injury and cell death regardless of the injuring agent” (Heuther & McCance‚ 2012). Cellular injury arises when a cell is unable to sustain homeostasis. The injury can be reversed if the cell can recover from whatever damage was done but if it does not recover the cell will die. The three common forms of cell injury are hypoxic injury‚ free radicals and reactive oxygen species injury‚ and chemical injury. The most common form of cell injury is hypoxic injury‚ or

Transport Processes (SKKK 2313) ASSIGNMENT # 1 1. Consider a steam pipe of length L=20 m‚ inner radius r1=6 cm‚ outside radius r2=8 cm‚ and thermal conductivity k=20 W/m.k. The inner and outer surfaces of the pipe are maintained at average temperatures of T1=150oC and T2=60oC‚ respectively. Obtain a general relation for the temperature distribution inside the pipe under steady conditions‚ and determine the rate of heat loss from the steam through the pipe. Assume that heat transfer is one-dimensional

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

MECHANISMS Definitions and Terminology 1. Introduction The subject Theory of Machines may be defined as that branch of Engineering-science‚ which deals with the study of relative motion between the various parts of a machine‚ and forces which act on them. The knowledge of this subject is very essential for an engineer in designing the various parts of a machine. 1.1 Sub-divisions of Theory of Machines The Theory of Machines may be sub-divided into the following four branches: 1.
