Robert Brown

Robert Brown Biology is a very broad topic and many scientists have contributed to the biology world. In this paper I will be talking about one of those people who had a major contribution to the science community. “Robert Brown was born on December 21, 1773 in Montrose Scotland. He died on June 10, 1858 at the age of 84 in London England” (Britannica 1). Robert Brown most recognized by how he described the “cell nuclei and the continuous motion of minute particles in solution, which came to be called Brownian motion” (Britannica 1). “His work revealed the random movement to be a general property of matter in the state, and the phenomenon has long been know as Brownian motion in his honor” (Britannica 2). Scientists extensively misunderstood…

Robert and Bessie Brown, who are the paternal grandparents of the author’s wife, made their home in Bradley, South Dakota, a modest farming community and rail hub on the eastern Dakota prairie. Bessie grew up on a farm near Bradley; whereas Robert, a veteran of the Great War, arrived at Bradley subsequent to purchasing the town’s Ford dealership. Throughout their married lives, the civic-minded couple assumed active service roles in community affairs, often accepting leadership in their church…

A shy, sassy girl with brown straight hair, deep dark brown eyes, was named Chloé Brown; lived in a nice modern gated community with her family. Her parents were the type of parents that everyone could ever dream of having; comical, admirable and mainly laid back but also have a strict side. Even though Chloé had the “perfect” life that everyone was jealous of, she did not understand to appreciate when she was an arrogant, sassy fifteen-year-old freshman at Avon Park High School. She hated…

molitor. During our second experiment, the colours of the T. molitor was noted, and the two T. molitor of dark brown colour used, moved relatively slow as compared to the others. Our results showed that the two dark brown T. molitor moved a mean distance of 3.8cm, whereas the three black T. molitor of the same trial moved a mean distance of 17.6 cm (one moved an abnormal amount of 28cm), the two brown T. molitor moved a mean distance of 9.05 cm (one of them was missing 2 legs), and the three…

A fit 35 with a well honed body carrying no excess fat. A couple of inches over 6 foot in height. Black hair combed straight back with no parting. Kind brown eyes over drawn cheeks and thin lips. Wearing a white check short sleeve shirt and grey flannelled trouser with woollen cardigan. No shoes on, showing both his socks were darned with different coloured wools. Rose, upstairs in bed, was finding it difficult to read the Daily Express news paper, which was two days old anyway. Listening to the…

at the painting it is clear to see that the man is seated at a table with his elbows rested on the surface. His two frail hands are folded together and pressed against his forehead, as if he is bowing his head in prayer. Placed on the table in front of him is a loaf of bread with one end cut off, a bowl containing liquid of brown color, a knife which is right next to the bowl, a thick bible with a green cover, and laying on top of the bible is a pair of glasses folded, laying upside down. The…

arranged in a hectic manner. At the back, a wooden hourglass can be seen along with a brown and green book. To the side there’s a wooden cigarette holder, with cigarettes burning and an open book. Next to this is an open pocket watch and glasses. A page is falling. A flute intersects this, and a fallen green, glass vase is on top. Almost central, there’s a skull and a bone, leaves embrace these. Light is coming from the top right corner, which is largely empty and a dark background. The overall…

Once bright green grass seems to turn patchy as the mood of the film shifts. Dead brown grass is first visible when Mia jumps the fence into Conor’s backyard. Dull colored grass is made visible again in a larger quantity when Mia kidnaps Conor’s daughter Kira and leads her into a field. The field is vast and brown, bordering a body of water that appears to be almost grey in color. Another aspect of nature that changes color with the mood of the film is the sky. In the majority of Fish Tank the…

The results showed that a brown color change occurred in the mixture. The reasoning behind the color change in the mixture has to do with the chemical reaction that changes catechol into its oxidized form benzoquinone. This chemical reaction also requires oxygen, and an enzyme called polyphenol oxidase. The enzyme polyphenol oxidase is needed because it acts as the catalyst in the reaction. When the components of buffer, substrate, and enzyme were mixed, the oxygen in the surrounding air also…

catalysts that increases the rate of chemical reactions (JRank Articles). With the use of enzymes it can accelerate certain reaction rates at a faster past then if the reaction was moving at it natural speed (JRank Articles). The activity of enzymes are control by many things like environment, inhibitors, and regulatory binding sites that happens on the enzyme(JRank Articles).The overall reaction in the natural setting which was the basic reaction in this experiment was in a time period of…
