- Diagram in two boxes: when too warm, sweat evaporates and dermal arterioles widen; when too cold, the arterioles narrow, most of all in the fingers and nose tipImage: RN Collins studio, code-drawn. Checked against OpenStax 5.3: sweat evaporation cools; dermal arterioles dilate to dissipate heat, constrict to minimize heat loss, particularly in the ends of the digits and tip of the nose (source lines drawn on the graphic)
- Slide 4
- Three result rows: back pocket for 48 hours, little or no growth; armpit sensor test for 48 hours, stayed in 25 to 35 degrees Celsius; armpit with koji for 60 hours, grew a little slower than an incubatorImage: RN Collins studio, code-drawn. Checked against Experiments page: #1 minimal to no growth; #2 armpit, sensor only, within 25-35 C for 48 h; #4 armpit, 60 h, koji grew, slightly longer than an incubator (source lines drawn on the graphic)
