b. The genetic variaiton among coral reefs in the Caribbean and Pacific Oceans

c. The variaiton in the algal communities among coral reefs

Answer 1

1a) If we examine the tree of life we can understand that the archea and eukaryotes share a more recent common ancestor than with the bacteria. Here given, Thermus aquaticus and cyanobacteria belong to bacteria, extremophilic archea belong to archea and dinpflagellates belongs to eukaryotes. as humas are eukaryotes more related to dinoflagellates(d)

1b)Biodiversity refers to the variety of plants and animals ina habitat. (a) refers to the number of species of fishes(different species of fishes) (b) and (c) refers to the genetic variation so all these are examples off biodiversity
