The Hit of a Lifetime free essay sample

I was starting varsity at second base and contributing to my team in any way. I was doing what I needed to do. Our team was a force to be reckoned with In this state, and we knew It. Our first test was the MASC. championship game, a home game. The cards were laid out great for us. We were hosting Princeton High, who later became the 2012 state champions. The day came, but we only played a few Innings before the skies unleashed on us with rain and lightning. The players, coaches, umpires, and a few dedicated fans tried to Walt out the storm. We waited until around 1 1 p. , when the umpires decided to postpone the game until the next day. The agony of waiting can play mind games with you. All night and all the next day, you wait and anticipate that championship game. The time finally came, and Mother Nature was finally a baseball fan.

You could smell baseball in the air. The game started and went back and forth many times. At this point, we were taking anything we could get, scraping and clawing for any type of spark.As the game went on, our endurance was tested, and the score was tied at the end of the 7th inning. Our first extra inning we fought on to keep the score tied. We were up to bat last, since we were the home team. I got the chance of a lifetime, a moment that could define my rather short life up until then. I came up to bat with two outs in the bottom of the 9th inning. The first pitch was high and outside. The second pitch was released, a survivable on the outer side of the plate. I put every ounce of effort and will into the swing and watched it pop off my bat.I darted running and was stunned to see the ball sail over the left field fence. I had hit the game winning homerun in the championship game, and when I came around heading to home my baseball family mobbed me at the plate. It was quite a moment, a moment In which my life was defined. I have always worked hard In athletics because Im not one of the naturally gifted athletes. Vive accepted this fact and I love the challenge to make myself better. Vive done It my whole life. On this day, my athletic life was defined and changed forever. I saw firsthand that hard work eventually pays off.I vowed to make myself better every day that I had the opportunity.

The Laws of Thermodynamics in Biological Systems

The Laws of Thermodynamics in Biological Systems The laws of thermodynamics are important unifying principles of biology. These principles govern the chemical processes (metabolism) in all biological organisms. The First Law of Thermodynamics, also known ​as the law of conservation of energy, states that energy can neither be created nor destroyed. It may change from one form to another, but the energy in a closed system remains constant. The Second Law of Thermodynamics states that when energy is transferred, there will be less energy available at the end of the transfer process than at the beginning. Due to entropy, which is the measure of disorder in a closed system, all of the available energy will not be useful to the organism. Entropy increases as energy is transferred. In addition to the laws of thermodynamics, the cell theory, gene theory, evolution, and homeostasis form the basic principles that are the foundation for the study of life. First Law of Thermodynamics in Biological Systems All biological organisms require energy to survive. In a closed system, such as the universe, this energy is not consumed but transformed from one form to another. Cells, for example, perform a number of important processes. These processes require energy. In photosynthesis, the energy is supplied by the sun. Light energy is absorbed by cells in plant leaves and converted to chemical energy. The chemical energy is stored in the form of glucose, which is used to form complex carbohydrates necessary to build plant mass. The energy stored in glucose can also be released through cellular respiration. This process allows plant and animal organisms to access the energy stored in carbohydrates, lipids, and other macromolecules through the production of ATP. This energy is needed to perform cell functions such as DNA replication, mitosis, meiosis, cell movement, endocytosis, exocytosis, and apoptosis. Second Law of Thermodynamics in Biological Systems As with other biological processes, the transfer of energy is not 100 percent efficient. In photosynthesis, for example, not all of the light energy is absorbed by the plant. Some energy is reflected and some is lost as heat. The loss of energy to the surrounding environment results in an increase of disorder or entropy. Unlike plants and other photosynthetic organisms, animals cannot generate energy directly from the sunlight. They must consume plants or other animal organisms for energy. The higher up an organism is on the food chain, the less available energy it receives from its food sources. Much of this energy is lost during metabolic processes performed by the producers and primary consumers that are eaten. Therefore, much less energy is available for organisms at higher trophic levels. (Trophic levels are groups that help ecologists understand the specific role of all living things in the ecosystem.) The lower the available energy, the less number of organisms can be supported. This is why there are more producers than consumers in an ecosystem. Living systems require constant energy input to maintain their highly ordered state. Cells, for example, are highly ordered and have low entropy. In the process of maintaining this order, some energy is lost to the surroundings or transformed. So while cells are ordered, the processes performed to maintain that order result in an increase in entropy in the cells/organisms surroundings. The transfer of energy causes entropy in the universe to increase.
