My friends and I decided to go to the beach on the first day of spring. On our way‚ we drove down Gateway Avenue‚ a street that happens to be lined with scads of Japanese flower trees. “Those are cherry blossoms. It is sometimes called the sakura after the Japanese. During World War 2‚ the cherry blossom was used to motivate the Japanese people”. I told my friends. Of course I received the inevitable question from the back seat‚ “How do you know that?” I had to ponder about that for a minute and

Talented My dad always told me that I was good in sports. I just have a natural tendency to pick up on a sport quickly and excel through it. Hey I’m just gifted like that so don’t be jealous because you wish you were me‚ you wish you had my talent. When I was around six years old‚ I was introduced into the sport of street hockey. According to my neighbour Carson‚ street hockey was a really big thing on my street back then. It was very popular‚ like the NHL is nowadays. The game

Santiago Neville Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚

Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule

Bushra Hanaif Professor Kristen Przyborski BI 121-02 April 14‚ 2013 1) In the 1940s‚ some physicians prescribed low doses of a drug called dinitrophenol (DNP) to help patients lose weight. This unsafe method was abandoned after a few patients died. DNP uncouples the chemiosmotic machinery by making the lipid bilayer of the inner mitochondrial membrane leaky to H+. Explain how this can cause weight loss. In a coupled reaction‚ an exergonic reaction provides the energy needed to drive an endergonic

Biology Assessment #4 Australian Megafauna: Thylacoleo Carnifex & Diprotodon Optatum Part A: The term Megafauna means ‘big animals’‚ and refers to animals with a body mass of over 40 kilograms. In general use‚ the term Megafauna is used to refer to the animals that evolved after the dinosaurs became extinct 65 million years ago. The extinction of the dinosaurs meant that the large number of birds‚ mammals and reptiles‚ which were left over‚ were able to evolve and dominate the earth.

Urinary System: Anatomy Review 1. Name the organs in the urinary system: 1. 2 kidneys 2. 2 ureters 3. bladder 4. uethra 2. The kidneys are retroperitoneal (behind the peritoneum)‚ lying against the dorsal body wall in the upper abdomen. 3. The adrenal gland sits atop the kidneys. Blood vessels enter and leave the kidney at the renal cortex. 4. The functional units of the kidney are the nephrons. They are called renal pyramids if they are located mainly in the cortex. They are called renal

Water molecules move from high to low Osmosis is what they seem to know Solute and Solvent are what’s inside The polarity of water makes it easy to find “Hyper” and “Hypo” tells you how much is there But isotonic means that they are fair Water molecules move from the inside out Scientists call this plasmolysis without a doubt All of this happens inside a membrane It is a serious matter‚ not a fun little game When a membrane is selective it chooses what it wants Few things are moved through
