Estimated time to complete: 2 hours

As noted by Gingras et al (2015), emotional stimulation has been known to lead to pupil dilation and contraction. For dilation of the pupils to occur during the listening of music, the special senses must work in conjunction with the autonomic nervous system (ANS). In addition, for this study to be physiological fact, the special senses and the ANS must also work collectively with the peripheral nervous system (PNS) and central nervous systems (CNS).

Instructions:

Read the attached article, The Eye is Listening: Music-Induced Arousal and Individual Differences Predict Pupillary Responses. During the reading, take notes and consider the following: The role of each neurological system (ANS,….

Data Tables and Post-Lab Questions

Table 6: Sucrose Concentration vs. Tubing Permeability

Post-Lab Questions

1. For each of the tubing pieces, identify whether the solution inside was hypotonic, hypertonic, or isotonic in comparison to the beaker solution it was placed in.

2. Which tubing increased the most in volume? Why?

3. What does this tell you about the relative tonicity between the contents of the tubing and the solution in the beaker?

4. What would happen if the tubing with the yellow band was placed in a beaker of distilled water?

5. Osmosis is how excess salts that accumulate in cells are transferred to the blood stream so they can be removed from the body. Explain how this process works in terms of tonicity.

6. How is….

EXPERIMENT 5: THE IMPORTANCE OF CELL CYCLE CONTROL Data

1.

2.

3.

4.

5.

Post-Lab Questions

1. Record your hypothesis from Step 1 here.

2. What do your results indicate about cell cycle control?

3. Suppose a person developed a mutation in a somatic cell that diminishes the performance of the body’s natural cell cycle control proteins. This mutation resulted in cancer but was effectively treated with a cocktail of cancer-fighting techniques. Is it possible for this person’s future children to inherit this cancer causing mutation? Why or why not?

4. Why do cells that lack cell cycle control exhibit karyotypes that look physically different than cells with normal cell cycle control?

5. What are HeLa cells? Why are HeLa cells appropriate for this experiment?

6. Research….

A Grumpy Old Man

From behind the curtain of an ER cubicle, we overhear the following dialogue:

Ernest: (Groans with pain) When’s that doctor going to come back? He said he’d only be a few minutes. I want to go home. I’m missing Golden Girls and it’s that episode where Rose tries to coach the peewee….

Part I – Emergency Mrs. Helms came in through the front door of her house with an armful of groceries. She put the bag down on the kitchen counter and called to her husband. “Herb, I’m home! Are you ready for lunch?” She didn’t get an answer, so she walked to the living room and found Mr. Helms lying on the fl oor. “Herb! Are you okay?” she asked as she grabbed his shoulder. Mr. Helms responded weakly while clutching his chest. Mrs. Helms frantically called 911. It only took EMS a few minutes to arrive and the paramedics transported Mr. Helms to the hospital. Upon admission to the….

Max’s Maximum: A Case Study on the Urinary System

It took the diagnosis of high blood pressure (hypertension) at the age of 45 to shock Max into taking better care of himself. A former college football player, he had let himself go, eating too much junk food, drinking too much alcohol, sitting on his chubby bottom for the majority of the last two decades, and even indulging in the frequent habit of smoking cigars. Max’s physician had to prescribe two different antihypertensive medications in order to get his blood pressure under control. She also prescribed regular exercise, a low-salt diet, modest alcohol intake, and smoking cessation. Max was scared, really scared. His father had hypertension at a young age as well, and….

EXPERIMENT 2: EFFECT OF CHELATION THERAPY ON ARTERIAL PLAQUE LEVELS Data Tables

Table 3: Eggshell Observations

Post-Lab Questions

1. Describe the differences you observed between Beaker 1, Beaker 2, and Beaker 3.

2. Does Beaker 3 serve as a positive or negative control? How do you know?

3. Research and determine the composition of eggshells. State your findings below, and indicate why this composition makes eggshells a good material for EDTA to chelate.

4. EDTA is a synthetic amino acid, which the body perceives as a foreign substance. EDTA is therefore delivered to the kidneys and removed from the body in urine. Explain how this process also leads to the removal of heavy metals.

5. Based on your results, do you believe chelation therapy would be an effective treatment for atherosclerosis?….
