significantly more nongated K+ channels than cell B‚ which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular concentration of Na+ on the magnitude of the action potential

Mayra Guadalupe October 29‚ 2012 The effect of temperature on beet cell membranes Introduction: Cell membrane is the plasma like substance that separates different organelles and molecules within an organism. The cell membranes vital function is to permit passage of protein and enzymes through their wall. Red beets‚ also known as Beta Vulgaris has a red pigment that is located in its large central vacuoles. It is my hypothesis that if the cell membrane is to experience extreme temperatures

The aim for this experiment is to investigate the effects of different storage environments on organic and non-organic bananas‚ to see which one lasts the longest over a period of time. The study was separated into 5 groups that were each labeled to a location in a standard family home that would‚ over time‚ begin to affect the overall form and characteristics of the bananas. Throughout the experiment‚ it was found that “Group 2 – Impact of Air Exposure‚” lasted longer than any other group. Following

Effects of Organic Food on Drosophila Melanogaster A new study has shown that fruit flies that lived on organic foods tended to be healthier than those that lived on conventional foods. The two things that researchers based their conclusions for health on were fertility and longevity. These two things are two important aspects to a fly’s life. On both of these tests‚ the flies that were fed organic food performed better than the flies that were fed conventional food. They survived for a longer

BIOL 2010 ANATOMY AND PHYSIOLOGY I Chapter 4: TISSUES AND MEMBRANES Outline of Notes I. Introduction. A. General: Cells are highly specialized and interdependent on one another. Groups of similar cells performing similar functions are called Tissues The study of tissues is called Histology. Organs are made of tissues. A detailed understanding of tissues will greatly help your understanding of organs and organ systems later in this course. Tissues are classified into 4 main types:
