Which one of the following pairs is correctly matched?
Correct answer: D. Streamlined body - aquatic adaptation
- A. Parasitism - intraspecific relationship
- B. Uricotelism - aquatic habitat
- C. Excessive perspiration - xeric adaptation
- D. Streamlined body - aquatic adaptation
Explanation
A streamlined body is a secondary aquatic adaption. It is found in animals that live permanently in water but most of them are amphibious in nature. The streamlined body consists of compression of head, body and tail into a curved streamlined form. There is no protruberance over the body so that the animal can move easily through water. Parasitism is a relationship between two organisms of different species in which one organism called a parasite obtains its food directly from another living organism called the host. In xeric adaptations, perspiration is reduced to conserve water. Uricotelism is characteristic of terrestrial animals which excrete uric acid.
