What does the term "biodiversity" refer to in the field of biology? a. Total number of species on earth. b. Genetic variation that exists within populations all of the earth's species. c. Total number of Earth's ecosystems. d. All of the above are correct What are examples of non li...
Competition in biology refers to the interaction between two species in which they fight for food or other resources as a prize for winning. Because of the shortage of resources, species struggle for them, leading to competition between them. Interspecific competition ...

The refuge-forming species is Diopatra cuprea, an onuphid polychaete which inhabits shallow water, medium-grained sand flats from Cape Cod to Florida. The abundance and species richness of other members of the infauna are shown to be positively associated with the presence of the tubes of ...
Polyploidy refers to the genome-﹚ide multiplication of chromosomes and is thought to have played a major role in the diversification of angiosperms. Understanding the distribution of ploidy levels in natural systems is an important area of evolutionary biology that has been greatly facilitated by the...
According to the fossil record and molecular biology data, giant pandas emerged as a species over 8 million years ago (Fig. 1). In the mid-Pleistocene, they were widely distributed from Zhoukoudian in Beijing in the north, to the south-east coast of China and surrounding countries such as ...
