Visualize that a patch clamp experiment revealed what could be a new potassium ion channel in mouse neurons. Recordings from the mouse neuron showed a potassium outward current in response to a depolarization by 10 mV from -68 to -58 mV. (The resting membrane potential was -68mV). When the calcium ion concentration was raised from 2 to 8 mM in the extracellular medium, the potassium outward current increased by about 50% from 4 µA to 6 µA. The sodium inward current remained unchanged. The calcium mediated effect on the potassium current is immediate. What type of potassium channel could be involved and how could this channel affect the generation of action potentials? Explain

it would be c. xylem.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
