My heart rate should remain the same as it always has been. My heart rate should be increase, but then over time go back down to what it was before the jumping jacks. My heart rate should have increased, and continued to keep going up until I either get food or pass out. Only then will it go down. My heart rate should have slowed down after doing the jumping jacks. According to the lab, what should have been the result of turning the lights off and on for a minute? My eyes should do nothing. My pupils should not react to the light or darkness at all. My eyes should only react to the light. They would get really small. My eyes in darkness would remain the same no matter what happens. My eyes should relax when it dark and my pupils become wider. When the light turns on they should shrink and get smaller. They would adjust. Laser eyes. I should be able to shoot lasers from my eyes. pew pew pew. Solve for the following problem. If you did the lab and were participating in the lab you will get the answer correct.A student ran in place for one minute. Afterwards they measured their heart rate. After 15 seconds they came up with 43 beats from their pulse, what is their ACTUAL heart rate?60 seconds = 1 minute. Think about how much 15 seconds is to a minute.Answer the following questions. 33 BPM 14 BPM 645 BPM 172 BPM
