Carbon cycles through the ecosystem between the atmosphere, organisms (such as producers, herbivores, and carnivores) and decomposers. This natural cycle maintains a somewhat constant level of carbon in the atmosphere. The burning of fossil fuels rel Continue Reading...
Sexuality Sex can be described as a biological distinction between males and females, particularly regarding reproductive functions. On the other hand gender tends to concentrate on socially constructed differences between men and women that reveal Continue Reading...
Genetic diversity: Discuss the issues related to genetic diversity: mutations, sexual reproduction, migration, and population size. Under most circumstances, when "an individual possesses a trait or traits that allow it to compete better for food, s Continue Reading...
After all, it remains within the female's best interest to mate with a newly dominant male, even if he has killer her infant. Ultimately, this is because the female, having lost her offspring, needs to remain reproductively competitive and to mate w Continue Reading...
The climax community in this case occurs when the rate of inhibition on the comb reaches a point that the balance between the Beroe and the comb is equal, which in turn equalizes the zooplankton levels, which equalizes the phytoplankton, which equal Continue Reading...
Kin Selection The organization and functioning of human and animal societies has long been the subject of intense investigations by natural scientists, sociologists and geneticists. Darwin, who laid the foundation for modern theory of evolution, sug Continue Reading...

Grammaticalization requires specific contexts to take place, and it can be, and has been, described as a product of context-induced reinterpretation. Accordingly, context is a crucial factor in shaping the structure of grammatical forms - to the ext Continue Reading...
Conservation Biology Explain what conservation biology is and highlight its goals. Conservation biology is a branch of biological sciences which is primarily concerned with the preservation of life on earth including organisms which are classified Continue Reading...
In this regard, Norton points out that, "Once xeriscaping becomes an element of the community's identity, and citizens encourage a change in the tastes of their neighbors, a trend toward less water use and more native habitat might build on itself, Continue Reading...
Nevertheless, it is a conceptual change from government-sponsored conservation efforts of the past, which might have focused specifically in the same region on the manatee population, and thus played a pure game of numbers. To regard the Florida man Continue Reading...
The fact is that numerous rooted macrophyte structures are not full of naturally strong and healthy particles and sediments and nutrients. It is because of the restriction or absence of these particles, sediments and nutrients that the study of the Continue Reading...

The authors explain that "Large-scale habitat loss and fragmentation…" that results from urban sprawl is a major cause of the lack of biodiversity within the insect species (Acharya, 1999, 27). Even the building of a new road, or street lights Continue Reading...
Otherwise more data and creative solutions would be required in order to get some sense of how to maintain eel populations. The notion of doing a population survey in the Sargasso Sea is tempting, although it is difficult to see how this would be a Continue Reading...
