A gene mutation is a change in the sequence of nucleotides that occurs during cell replication (mitosis and meiosis)within a single coding section of DNA. Mistakes can also occur in the transcription of mRNA or the translation of a polypeptide. However these changes are not considered to be mutations because they are not permanent changes to the cell. True / False.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
