UWP 102E Simplify‚ Clarify‚ & Correct III Optional Exercise: If you choose to do this exercise and submit it for a letter grade. The letter grade earned for SCC III will replace the lowest letter grade first recorded for SCC I and SCC II (i.e.‚ lowest of the two swapped out and replaced with SCC III grade). ______________________________________________________________________________ Directions: Rewrite the following 20 sentences to get rid of dead wood‚ jargon ("hit list" words/phases)

The number of cancer cases around the world has been increasing‚ and it is expected to increase to 24 million by 2035. The most commonly used cancer treatment is chemotherapy or chemo. Chemotherapy drugs are strong medicines that work to kill cancer cells. They can be divided into several groups based on factors such as how they work‚ their chemical structure‚ and their relationship to another drug. Knowing how the drug works is important in predicting side effects‚ because chemotherapy drugs kill

Crude oil is a naturally occurring‚ unrefined petroleum product composed of hydrocarbon deposits. It is a fossil fuel‚ meaning that it was made naturally from decaying plants and animals. Crude oils vary in color‚ from clear to tar-black‚ and in viscosity‚ from water to almost solid. Crude oil can be refined to produce usable products such as gasoline‚ diesel and various forms of petrochemicals and as such‚ are a useful starting point for many different substances. Crude oil is also a naturally

Methods for studying cells in the lab Centrifugation A centrifuge is a device for separating particles from a solution according to their size‚ shape‚ density‚ viscosity of the medium and rotor speed. Centrifugation can be used to separate cells from one culture or to isolate an organelle from the rest of the cell. The process relies on speed; the faster and longer the particle is centrifuged‚ the smaller the particles are that will be separated. Separation occurs by causing the larger particles

chunk of coal. I chose this quote because it shows how powerful this volcano is. The Volcanic ash that erupted from the mouth of the stratovolcano condensed into pebbles of ash‚ and chunks of coal from the volcano. At that time the lava with high viscosity had not erupted yet. The VEI of the volcano on the convergent boundary between the African and Eurasian plate is 7 on the scale. ~Armeet Chhina People in Pompeii had no idea what was going on because there was no word in latin for volcano and they
