Resting potential is created by a transport protein called the sodium-potassium pump. Resting potential occurs when ions are distributed unequally on the inside and outside of cells‚ and when cell membranes are selectively permeable to different ions. K+ is particularly important for the resting potential. The membrane is highly permeable to K+. In addition‚ the inside of the cell has a high concentration of K+ and the outside of the cell has a low concentration of K+. K+ will naturally diffuse

Introduction Molecules are constantly in motion due to thermal energy. Therefore‚ the molecules will move around and bump into each other. Because of this‚ molecules tend to spread out evenly into available space in a process called diffusion. Diffusion is the random process of molecules moving from areas of high concentration to low concentration‚ thus requiring no energy. Many of the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement

something is able to change its environment or itself‚ it has energy. When you think of energy‚ you might think of action- or objects in motion‚ like the baseball that shatters a window. There are different forms of energy. Turn on an electric light and a dark room becomes bright. Turn on a music player and sound comes through your headphones. In both situations‚ energy moves from one place to another; effect and reaction. The two different types of energy are kinetic and potential energy. Kinetic

What is the work done by the gravitational force? And what is the change in PE? (Notice anything?) Solution: PE= m*a*h PE= (0.15kg) (9.8 m/s^2) (9.0) PE= 13.23 kg m^2/s^2 or J - The change in PE and the calculated on the 1st question are the same. 7.

multiracial. Researchers have noted that there is little literature within the counseling field to address the topic of working with multiracial clients‚ but Adlerian therapy has been found to be effective for working with multiracial clients because this theory examines the social environment of an individual. One of the goals of this type of therapy is for a client to make decisions and define themselves‚ instead of being put into a generalized category. Adlerian theory recognizes that people are part

Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement
