1 Common triggers of an anaphylactic reaction include drugs, such as penicillin, insect stings, foods (peanuts, shellfish), X-ray dye, and latex. 2  The symptoms of anaphylaxis may vary and can include hives, tongue swelling, vomiting, and even shock.  If someone is at risk, avoidance is the best form of treatment.
Ocean regions with high concentrations of phytoplankton will have shades of blue-green depending upon the type and density of the phytoplankton population there. The basic principle behind the remote sensing of ocean color from space is that the more phytoplankton is in the water, the greener it is.
It changes color with the light and the color of the sky, from green to blue to gray. At â¦ twilight, you can't tell the ocean from the sky. Ripples and waves continuously flow toward you, eventually break into foam, creep up to your feet, and slide back. The ocean makes a sound like water surging and retreating.
