Should Steroids Be Banned?It is amazing what athletes will do to achieve higher levels of performance and to sometimes get the extra edge on the competition. Most of the time people do not realize the long-term effects that result from the decisions they make early in life. This resembles the use of steroids in a…

Anabolic steroids are powerful muscle-building and performance-enhancing compounds. They are many times used as the “secret-weapon” behind many world-class athletes, their performance, and bodybuilding. Steroids increase the amount of muscle one can build. They are banned by almost every athletic organization and are illegal, therefore leading to arrests and jail time if one is caught…

18. 11. 01Osmosis InvestigationTo investigate the effects of changing the sucrose concentration on osmosis in plant cells. Water passes into cells through a special type of diffusion called osmosis. Water molecules diffuse through the membrane from a weak solution into a strong solution until the concentration is the same on both sides. A membrane that…

Detection of Biological MoleculesIntroduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus,life wouldn’t exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds,and disulfide bonds. Covalent bonds are especially strong, thus, are present inmonomers, the building blocks of life. These monomers combine to…

Asteroids are rocky and metallic objects that orbit the Sun but aretoo small to be considered planets. They are known as minor planets. Asteroids range in size from Ceres, which has a diameter of about 1000 km,down to the size of pebbles. Sixteen asteroids have a diameter of 240 kmor greater. They have been found…

in molecules of relatively small mass. This peculiarity creates the unique properties associated with substances with hydrogen bonding, especially in H20. In most compounds, the polarity of its elements has a negligible effect on the dipole forces which connect them. However, when hydrogen bonds to a small and highly electronegative atom, such as N, O,…

The properties observed for matter on the macroscopic level are determined by the properties of the constituent molecules and the interactions between them. The polar or non-polar character of a molecule will clearly be important in determining the nature of its interactions with other molecules. There will be relatively strong forces of attraction acting between…
