9/24/2012 The End of the Race Thinking about the outcome of mixing races‚ are Asians and Europeans distinguishable in the distant future? As intermarriage goes intense‚ there would be many minorities in race. In contrast‚ majorities’ attitudes toward minorities generate discrimination simultaneously; minorities are more likely to be exposed to prejudice. However‚ Steve Olson says that each mixed individuals are the key to weaken the barricade between races. Matthijis Kalmijin

an ever-changing external environment. This steadiness is provided by the regulation of the movement of materials across its plasma membrane. Since not all substances penetrate the membrane equally well‚ the membrane is said to be differentially permeable. (IS) Diffusion is the tendency of molecules or ions to move from an area where they are in higher concentration to an area where they are in lower concentration‚ that is‚ down or along their concentration gradient. Fat-soluble solutes can diffuse

Should Scotland be Independent? There has been a wave of nationalistic fever sweeping the country ever since the SNP came to power in 2007. Independence is on their agenda and now there is a referendum set for 2014. But why should we go independent? After all‚ we have been married to England for over 300 years and our country is ‘too poor’ and ‘too wee’ to square up to the economic giants in the global market today and what would happen if the our banks were to self-destruct again

in distant parts of the room. It diffuses from the high concentration of molecules in the bottle to a lower concentration of molecules in the air. Osmosis is a type of diffusion. It involves movement of water through a differentially permeable membrane from a region of high concentration (of water molecules) to a region of lower concentration (of water molecules). We define 3 types of solutions based upon osmotic activity. In an isotonic solution‚ the solute concentration is

Based on your observations‚ is the sandwich bag permeable to starch? To iodine? - Iodine is permeable to the sandwich bag‚ while starch is not. 5. Look up the molecular structures of starch and iodine‚ and use those structures to explain your observations. - Starch is a more complex compound than iodine‚ making it easier

Chloroplasts are organelles present in plant cells and some eukaryotic organisms. Chloroplasts are the most important plastids found in plant cells. It is the structure in a green plant cell in which photosynthesis occurs. Chloroplast is one of the three types of plastids. The chloroplasts take part in the process of photosynthesis and it is of great biological importance. Animal cells do not have chloroplasts. All green plant take part in the process of photosynthesis which converts energy into

cross the membrane through simple diffusion‚ facilitated diffusion and active transport. Osmosis is thought of as the diffusion of water from an area of high concentration of water molecules to an area of low concentration‚ across a partially permeable membrane. To define osmosis more accurately we define it in terms of water potential. Water potential is a measure of how easy it is for water molecules to move. Diffusion occurs because substances attract a ‘cloud’ of polar water molecules around
