1) When you take someone’s pulse, you palpate an artery lying close to the surface of the skin, such as your wrist, and you can feel the artery expand as the intravascular pressure increases. Please take your own pulse and post the result in beats per minute (BPM). Refer to the topic reading “Your Heart Rate” to assist you in the procedure.
If your stroke volume is 500 ml, what is your cardiac output, based upon your pulse rate? If someone startled you during this activity, explain the effect it would have on your heart rate, stroke volume, and cardiac output.
2)What is the significance of plasmids found in bacteria? Explain with appropriate examples.
3)A recent superbug has been found in a patient in Pennsylvania, a strain of E.coli for which no antibiotic is effective. What has led to this strain for which, as a result, treatment is a challenge?
