Description of cystic fibrosis?
What has changed in cystic fibrosis to allow it to cause a genetic disorder? Explain how this differs from the gene's normal function.Is it possible for parents to not have the disorder, but pass it on to their children?
What kind of dominance pattern does cystic fibrosis show?
What problem(s) is/are caused to a person who inherits the cystic fibrosis gene? Is this typically inherited from the mother or the father?
Describe an experiment that you could use to determine if a new drug is effective at treating cystic fibrosis. Be sure to mention the independent, dependent and control variables.
How you could use the scientific method to draw conclusions about cystic fibrosis or to treat this disorder?

Visualizing the Data: The Composition of Human Urine
2 of 7
|
Review Human urine is made up of multiple components. Explore the composition of human urine in the interactive figure. Then answer the questions. |
Part A What percentage of urine is made up of chloride ions? Click on the top portion of the droplet. You may need to scroll down to see the percentage of chloride ions. Enter your answer as a whole number. % SubmitRequest Answer Part B Kidney failure may be detected by abnormally high levels of creatine in the urine. What is the normal percentage of creatine found in urine? Kidney failure may be detected by abnormally high levels of creatine in the urine. What is the normal percentage of creatine found in urine?
SubmitRequest Answer Part C What percentage of urine is made up of substances other than water and urea? Enter your answer to one decimal place. % SubmitRequest Answer Part D The hormone vasopressin is released from the pituitary gland when the blood is hypertonic (when the concentration of dissolved solutes in the blood is higher than that in cells). Vasopressin acts on nephrons in the kidneys to help restore proper fluid balance by drawing water back into the blood. What will the water content of human urine be when vasopressin is acting on the kidneys? What will the water content of human urine be when vasopressin is acting on the kidneys?
SubmitRequest Answer Part E Suppose you are planning to go to the movies with your friends. For you, the best thing about the movies is getting a large tub of salty popcorn. However, every time you do this, you tend to drink lots of water, too. What components in your urine would be most affected by your consumption habits at the movie theater? Select all that apply. Select all that apply.

A loss of function mutation in Cdc25 causes cells to divide later. In yeast, this causes the cells to become very large over time. Specifically, explain the effect of loss of function of the Cdc-25 protein on CDK activity. Also, explain why LOF of Cdc25 would inhibit the onset of DNA replication. Rubric (4): correct interpretation of the effect on CDK-cyclin with LOF Cdc-25 (2). Correct explanation of why DNA replication would not be initiated (2).
