Photosynthesis depends upon the absorption of light by pigments in the leaves of plants. The most important of these is chlorophyll-a, but there are several accessory pigments that also contribute.he measured rate of photosynthesis as a function of absorbed wavelength correlates well with the absorption frequencies of chlorophyll a, but makes it evident that there are some other contributors to the absorption.
I recently was catching up with your back podcast episodes and listened to The Man Behind the Maneuver, about Dr. Heimlich and his eponymous life-saving technique. I found it informative, insightful, humorous, and touching. The producer had a deft touch telling Dr. Heimlich's story, as well as his own.
1 If you are alone and choking, you can perform the Heimlich maneuver on yourself. 2  Use a kitchen counter, a desktop or a chair to apply pressure to the area above your navel and below your sternum repeatedly to force the food out, or take your fist in the same way and thrust it up underneath your sternum. That could further lodge the food, causing a total obstruction of the airway, Andersen explained. 2  Perform the Heimlich maneuver. 3  Wrap your arms around the choking victim's waist from behind. 4  With your strongest arm, make a fist with your thumb up and and put it above the choking victim's navel, below their sternum.
