As the hernia grows, it eventually causes an abnormal bulge under the skin near the groin. This bulge may become increasingly more uncomfortable or tender to the touch. As the hernia increases in size, a portion of herniated intestine may become trapped and unable to slide back into the abdomen.
Answer 1: Photosynthesis is the ability of plants to absorb the energy of light, and convert it into energy for the plant. To do this, plants have pigment molecules which absorb the energy of light very well. The pigment responsible for most light-harvesting by plants is chlorophyll, a green pigment. The green color indicates that it is absorbing all the non-green light-- the blues (~425-450 nm), the reds and yellows (600-700 nm).
This chlorophyll resides mostly in the chloroplasts and gives leaves their green color. The range of light absorption in leaves is extended by some accessory pigments such as the carotenoids, but does not cover the entire visible range-that would make the leaves black!rown algae have the pigment fucoxanthin in addition to chlorophyll to widen their absorption range. These red and brown algae grow to depths around 270 meters where the light is less than 1% of surface light. But the most advanced plants are the land plants, which have the least advanced system for gathering light!
