The cheek smear slide is made by taking a q-tip or toothpick, rubbing it on the inside of your mouth (to remove cells) and then wiping or smearing it onto a blank slide. A stain is used on the cells so that you can see them, otherwise, they would be see-through. Look at the cheek smear slide using the 10x objective (total magnification of 100x). Approximately how many cells do you see inside the red circle? Select one: a. 5...

The questions about mechanism of evolution
1. If you send a sample of your cheek cells to the company 23andMeTM, they will tell you your genetic ancestry. This is possible because certain alleles are associated with certain historic human populations (eg, GATTC in a particular location might be associated with Han Chinese ancestry). Most of the allele differences have no effect on phenotype. The table below lists four mechanisms of evolution. For each mechanism, circle and explain whether you think...

Take three cuvettes from the Containers shelf and place them onto the workbench. Take an Erlenmeyer flask from the Containers shelf and place it onto the workbench. There is a solution on the Materials shelf labeled 2% starch. This has a starch concentration of 1 mg/ml. In the Erlenmeyer flask, you should create 100 mL of a new starch solution that is 1/400th of the stock solution using water as the filler. How much starch and water should you add?...

/courses/1631958/q 2791378/take D Question 5 12 pts Pulse Rates of Men. A simple random sample of 40 men results in a standard deviation of 10.3 beats per minute (based on the data set provided). The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with...
