Here is a question about this article: The evolutionary relationships and heredity of a group of organisms is called its phylogeny. Phylogenetic studies attempt to discover phylogenies. The basic approach is to use similarities based on shared inheritance to determine relationships. As an example, species of Pereskia are trees or bushes with prominent leaves. They do not obviously resemble a typical leafless cactus such as an Echinocactus. However, both Pereskia and Echinocactus have spines produced from areoles (highly specialised pad-like structures) suggesting that the two genera are indeed related.
What is the answer to this question: What are areoles?
****
So... pad-like structures


Here is a question about this article: The malaria problem seems to be compounded by the AIDS epidemic. Research has shown that in Namibia the risk of contracting malaria is 14.5% greater if a person is also infected with HIV. The risk of death from malaria is also raised by approximately 50% with a concurrent HIV infection. Given infection rates this large, as well as a looming malaria problem, it may be very difficult for the government to deal with both the medical and economic impacts of this epidemic. The country had only 598 physicians in 2002.
What is the answer to this question: The risk of death by malaria raises by how much with a concurrent HIV infection?
****
So... 50%


Here is a question about this article: Birds have featured in culture and art since prehistoric times, when they were represented in early cave paintings. Some birds have been perceived as monsters, including the mythological Roc and the Māori's legendary Pouākai, a giant bird capable of snatching humans. Birds were later used as symbols of power, as in the magnificent Peacock Throne of the Mughal and Persian emperors. With the advent of scientific interest in birds, many paintings of birds were commissioned for books. Among the most famous of these bird artists was John James Audubon, whose paintings of North American birds were a great commercial success in Europe and who later lent his name to the National Audubon Society. Birds are also important figures in poetry; for example, Homer incorporated nightingales into his Odyssey, and Catullus used a sparrow as an erotic symbol in his Catullus 2. The relationship between an albatross and a sailor is the central theme of Samuel Taylor Coleridge's The Rime of the Ancient Mariner, which led to the use of the term as a metaphor for a 'burden'. Other English metaphors derive from birds; vulture funds and vulture investors, for instance, take their name from the scavenging vulture.
What is the answer to this question: John James Audubon later lent his name to which group?
****
So...
National Audubon Society
