Zippy was shrunk by Brutus Buckeye to the size of a cell. He then found itself hopping around the human body. Zippy observed two cells briefly connect with each other then the one cell increased its ATP production. Zippy realized that this cellular encounter was an example of (?) intercellular communication occurring by (?)
A. Direct, paracrines
B. Indirect, paracrines
C. Direct, juxtacrines
D. Indirect, juxtacrines
C. Direct, juxtacrines
At a recent vet checkup, Alena’s dog’s vitals included a 101F temperature reading. As the vet reported that all vitals were appropriate for her dog, Alena correctly realized that:
A. Her dog is utilizing our Critical Equation #1 in the forward direction to have these vitals
B. Her dog is in equilibrium
C. If this appt had occurred at 3AM instead of at 3PM, the temperature would have been the same
D. Her dog’s body temperature is maintained by a homeodynamic control system
A. Her dog is utilizing our Critical Equation #1 in the forward direction to have these vitals
Based on Bloom’s Revised Taxonomy, in the assessments this term, you will be required to (?) the material by doing actions such as (?)

B. All three are able to overcome the limitations of diffusion
C. Both statements are correct
D. Neither statement is correct
A. Only paracrines and neurotransmitters travel via the fluid between the cells
Dr. Gray’s Patient Y is experiencing delays in the function of their afferent pathways. Dr. Gray thus expects Patient Y to have:
