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.
To perform abdominal thrusts (Heimlich maneuver) on someone else: 1  Stand behind the person. 2  Make a fist with one hand. 3  Grasp the fist with the other hand.  Perform a total of 5 abdominal thrusts, if needed.
