Effects of Activators and Ethanol on Fermentation Rates In this lab we examined how the rate of fermentation is influenced by the type of substrate‚ and activators and inhibitors. We used four fermentation tubes in which we separately combined yeast with MgSO4‚ pyruvate‚ ethanol‚ and glucose. At five minute intervals we recorded the volume of gas produced in each fermentation tube. Our results are displayed in the graph. Our results supported the prediction that pyruvate is an activator

Malignant tumors establish new tumor distant from the primary tumors. Cancer cells characteristics distinguish them from normal cells. They have abnormal nuclei with many chromosomal irregularities. They form tumors because they do not exhibit contact inhibition. They induce angiogenesis and cause nearby blood vessels to form a capillary network that services the tumor. Normal cells can undergo the cell cycle for about 50 times and then they die. Cancer cells can enter the cell cycle repeatedly‚

each had the objective of understanding how various factors may have an influence on blood flow rate. These factors include the effect of blood vessel radius‚ the effect of blood viscosity‚ as well as the effect of blood vessel length‚ and the effect of blood pressure. This better understanding of cardiovascular dynamics was achieved with PhysioEx 9.1. Hypothesis: Hypothesis- Activity 1: Studying the Effect of Blood Vessel Radius on Blood Flow

(New) Hammurabi’s code: was it just Hammurabi‚ the king of the small city-state of Babylon‚ ruled for 42 years making 282 laws being written in cuneiform. Together‚ these 282 laws carved onto a large stone‚ make up what has come to be known as Hammurabi’s code. Hammurabi’s code was not just because some of the laws were not only greatly exaggerated towards those accused of crimes‚ but also the consequences of the suggested crimes were unfair and cruel when viewed through the 21st century perspective

proceeds from head to toe and from the midline to the periphery (outside boundary or surface of something). Different body parts grow at a different rate‚ all body parts cannot grow at the same time. Growth is a continuous and gradual process‚ all body parts continue to grow from infancy to late childhood. Although the patterns for growth are sequential the rate of growth is not uniform but more rapidly in early years and tends to slows down as we are in our later stages. Theorist has come up with different

Countries like China‚ Japan‚ Singapore‚ Australia & Pakistan have joined the project‚ Strategies to Prevent Suicide (STOPS)‚ in order to lessen their increasing number of suicide. However‚ in trying to prevent the increase in number of suicide deaths and attempts‚ one must know what the leading causes of it are. Suicide rates change over time‚ and the factors influencing them remain poorly understood. Economic

Enzymes are very large complex organic molecules that are synthesized by the cell to perform specific functions. These biological catalysts are important because they speed up the rate of the reaction that would otherwise be too slow to support life. Catalase is an enzyme present in the cells of plants‚ animals and aerobic

“sustainability”‚ I found the definition to be much different from mines. The actual meaning of the word sustainability in the dictionary is; the ability to be sustained‚ supported‚ upheld‚ or confirmed‚ which would relate to the topic of Hydraulic Fracturing. What is Hydraulic Fracturing you may say? According to Propublica.org‚ Hydraulic Fracturing is the process used in 9 out of 10 natural gas wells in the United States‚ Where millions of water‚ sand and chemicals are pumped underground to break apart the
