QUES: A parasitic relationship is one in which one member of the association benefits while the other is harmed. This is also known as antagonistic or antipathetic symbiosis. Parasitic symbioses take many forms, from endoparasites that live within the host's body to ectoparasites that live on its surface. In addition, parasites may be necrotrophic, which is to say they kill their host, or biotrophic, meaning they rely on their host's surviving. Biotrophic parasitism is an extremely successful mode of life. Depending on the definition used, as many as half of all animals have at least one parasitic phase in their life cycles, and it is also frequent in plants and fungi. Moreover, almost all free-living animals are host to one or more parasite taxa. An example of a biotrophic relationship would be a tick feeding on the blood of its host.

QUES: After 1937 the Lord Mayor and the state commissioners of Hanover were members of the NSDAP (Nazi party). A large Jewish population then existed in Hanover. In October 1938, 484 Hanoverian Jews of Polish origin were expelled to Poland, including the Grynszpan family. However, Poland refused to accept them, leaving them stranded at the border with thousands of other Polish-Jewish deportees, fed only intermittently by the Polish Red Cross and Jewish welfare organisations. The Gryszpan's son Herschel Grynszpan was in Paris at the time. When he learned of what was happening, he drove to the German embassy in Paris and shot the German diplomat Eduard Ernst vom Rath, who died shortly afterwards.
