Test of logic: “Critical speed is the boundary that separates running speeds that can be sustained in physiological homeostasis, from the speeds that cannot. Which statement below aligns with (i.e., it is in accordance with, or it follows) the concept of critical speed? (Choose 1 correct answer). 

The cat Phillipa has become anxious. She has lost weight, and she is restless and sleepless. You are a veterinarian specializing in endocrinology. Your first determine that Phillipa has high thyroid hormone levels in her blood. Your next step is to determine whether the problem lies at the level of her hypothalamus, anterior pituitary, or thyroid gland.  Question: You discover an endocrine tumor in Phillipa’s anterior pituitary. If this tumor is causing her symptoms, which hormone levels do you expect to find in her blood, compared to in a healthy cat? (Thyrotropin-releasing hormone = TRH, thyroid-stimulating hormone = TSH). There is 1 correct answer.

Identify a TRUE characteristic that can allow smooth muscle to use less energy when contracting compared to skeletal muscle. There is 1 correct answer.

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:

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.
