CHICAGO (Reuters) - Lab experiments on a new strain of the H7N9 bird flu circulating in China suggest the virus can transmit easily among animals and can cause lethal disease, raising alarm that the virus has the potential to trigger a global human pandemic, researchers reported on Thursday.
The answers are:
1) A
2)B
3)C
Answer: The correct answer for the fill in the blank is A) Found near coasts.
Chaparral biomes are found in small regions of almost every continent. This generally includes areas near the coast like the coastal areas of the Mediterranean. They have quite hot and dry cimatic conditions.
The different types of terrains in these biomes are slopes of mountains, rocky hills etc. The weather conditions change constantly in these biomes. Therefore, plants and animals found in these biomes adapt quickly to the changing environmental conditions.
In biology, the strain is a low-level taxonomic rank used in different contexts:
In microbiology, a strain is a part of a bacterial species different from other bacteria of the same species by a minor but identifiable difference. Strains are often created in the laboratory by mutagenesis existing strains or wild-type examples of bacterial species.
In zoology, a strain corresponds to an individual or group of individuals who are at the origin of a line of descendants, sometimes called the holotype, paratypes, etc. A strain is a population of organisms that descends from a single organism or pure isolate culture. Strains of the same species may differ slightly from each other in many respects.
A strain thus consists of a group of organisms of the same species possessing certain differential traits based on their relationship; either they come from the same region, as the same watershed of a river, or they are the fruit of a particular breeding program (exists as a whole interbreeding without introductions from external sources).
