Synthesis of 4‐methylcyclohexene via Dehydration of 4‐methylcyclohexanol Heston Allred TA: Christine Woolley Thursday 1:05-4 pm Laboratory Experiment #10 Abstract 4-methylcyclohexanol was synthesized to 4-methylcyclohexene using dehydration. 4-methylcyclohexanol was heated to reflux and the subsequent distillate (4-methylcyclohexe) was collected. It was then purified using sodium chloride to separate products and an anhydrous solid was then added and filtered

Excellent work! A cell goes from diploid (2N) to haploid (1N) during meiosis I when pairs of homologous chromosomes split apart into different daughter cells. This haploid condition continues during meiosis II when sister chromatids split apart during the formation of four daughter cells. Score for incorrect answer: 0 General feedback 1 (May include media. Include graphic and file name): Remember that a diploid cell has pairs of chromosomes—each pair represents one chromosome that came from the

In conclusion‚ the purpose of the lab Bird Adaptations was to act as a bird using different tools as a beak‚ and try to collect as many items as you can at each station in 15 seconds. Overall‚ the data collected throughout this lab supported each of my hypothesis. The data shows that certain “beaks” worked better than the other at collecting food. For example‚ the data shows that for the Seeds Station the tweezers worked best with an average of 9.3 pieces of food‚ the straw worked best for the Nectar

Biology 10 Vinegar Eel Lab Adam Dorner 1) The most toxic metals were silver‚ lead and iron‚ all killing the eels in under four minutes‚ with silver taking only 1 minute and 40 seconds to kill the eels‚ and only 13 seconds to make the eels stop forward motion. Strontium wasn’t effective as after 5 minutes of exposure to it‚ the eels hadn’t died or stopped forward motion. 2) a) The accepted toxicity varies from metal to metal. The accepted toxic level of lead is 0.0012 parts per million‚ however

Unit 10 Assignment 2: The Endocrine System: Diseases and Age-Related Changes Human Chorionic Gonadotropin (hCG) Human chorionic gonadotropin is a hormone that can be detected in the urine or blood of both males and females. It is more often seen in pregnant women but can also be found in cancerous tumors of the uterus and testicles. HCG aides in establishing pregnancy and has also been used here lately in some forms of weight loss programs although not always approved. Cushing’s Disease Cushing
