You are conducting research on a muscle-wasting disease in cats, and you need to know how a potential drug molecule (let’s call it X) enters the muscle. Is it simple diffusion through the lipid bilayer, protein-mediated diffusion, or some sort of active transport? Suppose that you can culture cat muscle cells in a petri dish, add X to the bathing saline, and measure the concentration of X inside the muscle after various periods of time. Question: If X is taken up by simple diffusion through the lipid bilayer, how will the rate of drug X entry into the cells depend on its concentration gradient ? Choose the 1 correct answer

Ohm’s law governs electrical potentials observed in nerve cells. Using Ohm’s law and ignoring units, if the current is 2 amps and the resistance is 5, what is the voltage across the resister?

Bone cells form concentric circles around longitudinal tubes called:

The hardness of a nail comes from:

The muscle tissue that can be consciously controlled is:

Sebaceous glands secrete:

Reminder: Cato, a Burmese cat, has lost interest in play and other activities. His cardiac output is in the normal range, but his heart rate is much higher than normal. His alveolar PO2 is higher than normal, while his alveolar PCO2 is lower than normal, and he is breathing hard all of the time. His arterial PO2  is lower than normal, as is his arterial percent hemoglobin saturation (below 70%). Question:  Which diagnoses align with Cato’s symptoms? There are 3 possible answer.

The subcutaneous layer consists of:

If blood pressure drops by 20% and cardiac output doesn’t change, how much does total peripheral resistance need to change (and in what direction) to restore blood pressure? There is 1 correct answer. 

Summarize these three “bad” abortion arguments I discuss in my Lecture this week, including my reasoning for why I view them as “bad”:“My Body My Choice”“Abortion is wrong since you might be aborting the next Beethoven”“Abortion is wrong because people should deal with the consequences/take responsibility for having sex”*** Remember that copying/pasting from any course materials (other than your own words in the Prep Guide), the internet, or using generative AI like ChatGPT to help “write” or “proofread” or “improve” your answer violates my Academic Integrity policy. Note that generative AI is now incorporated into many popular writing and translating platforms (e.g. Grammarly, Quillbot, Google Translate, DeepL, etc.), so if you’re using those platforms, you’re using generative AI in violation of my policy. USE YOUR OWN WORDS or, if you are unable to do that, properly quote/informally cite them as I discuss in the Academic Integrity section of the Syllabus ***
