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

Tara sees a commercial for a brand of pills that promise to boost energy and people perform better in work and school. as people in the commercial talk about how much better they feel when taking the pill, tara notices a message on the bottom of the screen that reads, "this pill is not approved by doctors and has not been tested in controlled experiments." what is the best conclusion that tara should make about the commercial? it is making scientific claims based on subjective observations. it is making scientific claims based on opinions instead of pseudoscientific facts. it is making pseudoscientific claims based on objective observations. it is making pseudoscientific claims based on opinions instead of scientific facts.

In many humans, exposing the skin to sunlight over prolonged periods of time results in the production of more pigment by the skin cells (tanning). this change in skin color provides evidence that -
