In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis

Biology 104 Reaction Times Objectives: 1. Formulate and test hypotheses regarding reaction times. Introduction: Reaction time is a measure of how quickly an organism can respond to a particular stimulus. Reaction time has been widely studied‚ as its practical implications may be of great consequence‚ e.g. a slower than normal reaction time while driving can have grave results. Many factors have been shown to affect reaction times‚ including age‚ gender‚ physical fitness‚ fatigue‚ distraction

As Americans returned to work‚ the theory went; they would have more money to spend on everything from clothes to vacations to houses. As demand rose for products and services‚ businesses would be forced to hire

Reaction Paper August 30‚ 2014; Saturday; 1:00pm until 3:00pm. Our group went to ZAEC Hospital which is located at the San Jose Road. Where we did our requirement to do a manual processing to produce a radiographic film that is a visible image. Before we accomplished our task‚ we started to pick or choose who will be the one who we should expose or examine and who will be the operator in the Operating Console. And also planned who will be the one would do the next

Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its

The National Economic and Development Authority (NEDA) said the country’s unemployment rate increased by 0.6 percent due to a lower level of employment amid a slightly higher labor force level. Majority of the unemployed were high school graduates (31.7 percent)‚ college graduates (21
