Core 1 summary notes 1) Fossils fuels provide both energy & raw materials such as ethylene‚ for production of other substances Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum Catalytic cracking is the process whereby high molecular weight fractions are broken down to low molecular weight ones. This process is used in petroleum refineries where crude oil is broken down to smaller alkenes and alkanes‚ until ethene‚ propene‚

kinases. The activity of CDKs rises and falls as the cell progresses through the cycle. Oscillation leads to cyclical changes in the phosphorylation of proteins that regulate major events in the cell cycle. DNA replication‚ mitosis‚ chromosome condensation etc. Key molecules (2): Cyclins Cyclines are CDK regulators. Unless tightly bound to a cyclin CDKs have no protein kinase activity. Cycles of synthesis and degradation hence the name. CDK levels remain constant. Cyclical changes in cyclin levels

The problem that was required to be investigated in this laboratory experiment was to determine which type of cleaning product would be able to prevent the most bacterial growth when placed in a neutral environment. In order to answer this problem‚ 8 different disinfectants were tested‚ including sterile water‚ and their after two days their zones of inhibition were measured and recorded. A hypothesis that was formulated before experimenting was‚ “If the type of disinfectant is Mouthwash‚ then it

in 1763 of repairing a model Newcomen engine for the University of Glasgow‚ and noted how inefficient it was. In 1765 Watt conceived the idea of a separate condensation chamber. Watt’s idea was to equip the engine with a second‚ small cylinder‚ connected to the main one. In Watt’s design‚ the cold water was injected only into the condensation chamber. Watt’s engine soon became the dominant design for all modern steam. A unit of power called the Watt was named after James Watt. In contrast

Many of us have been to water parks/ theme parks and probably never thought about how much water is being used. I especially have been intrigued with the fact that San Antonio has a Seaworld‚ because the other cities that have one are San Diego and Orlando. San Diego and Orlando both are by many beaches and land of water compared to San Antonio. So to me I felt that San Antonio having a Seaworld would have a major impact on our city water supply. How much water does Seaworld consume and or
