Information: - Oxypilinae is a subfamily of the mantis family Hymenopodidae . - Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see (crypsis), or by disguising them as something else (mimesis). Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of actively changing their skin pattern and colours, whether for camouflage or for signalling. - Flower mantises are those species of praying mantis that mimic flowers. Their coloration is an example of aggressive mimicry, a form of camouflage in which a predator's colours and patterns lure prey. Most species of flower mantis are in the family Hymenopodidae. Their behaviour varies, but typically involves climbing a plant until they reach a suitable flower, and then staying still until a prey insect comes within range. Many of these mantises have deimatic displays to startle or put off potential predators. - Hymenopodidae is a family of the order Mantodea (mantises), which contains four subfamilies. Some of the species in this family mimic flowers and are found camouflaged among them; these are called Flower Mantises. The coloration is aggressive mimicry, luring prey to approach close enough to be seized and eaten. - Aggressive mimicry is a form of mimicry in which predators, parasites or parasitoids share similar signals with a harmless model, allowing them to avoid being correctly identified by their prey or host. In its broadest sense, it could include various types of exploitation, as when an orchid exploits a male insect by mimicking a sexually receptive female (see pseudocopulation), but will here be restricted to forms of exploitation involving feeding. An alternative term Peckhamian mimicry (after George and Elizabeth Peckham) has also been suggested, but it is seldom used. The metaphor of a wolf in sheep's clothing can be used as an analogy, but with the caveat that mimics are not intentionally deceiving their prey. For example, indigenous Australians who dress up as and imitate kangaroos when hunting would not be considered aggressive mimics, nor would a human angler. Treated separately is molecular mimicry, which also shares some similarity; for instance a virus may mimic the molecular properties of its host, allowing it access to its cells. After reading the paragraphs above, we are interested in knowing the entity with which 'oxypilinae' exhibits the relationship of 'parent taxon'. Find the answer from the choices below.

Information: - Urea, also known as carbamide, is an organic compound with the chemical formula CO(NH). This amide has two NH groups joined by a carbonyl (C=O) functional group. - The hypothalamus (from Greek , "under" and , thalamus) is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis). - The prostaglandins (PG) are a group of physiologically active lipid compounds having diverse hormone-like effects in animals. Prostaglandins have been found in almost every tissue in humans and other animals. They are derived enzymatically from fatty acids. Every prostaglandin contains 20 carbon atoms, including a 5-carbon ring. They are a subclass of eicosanoids and of the prostanoid class of fatty acid derivatives. - Fever, also known as pyrexia and febrile response, is defined as having a temperature above the normal range due to an increase in the body's temperature set-point. There is not a single agreed-upon upper limit for normal temperature with sources using values between . The increase in set-point triggers increased muscle contraction and causes a feeling of cold. This results in greater heat production and efforts to conserve heat. When the set-point temperature returns to normal, a person feels hot, becomes flushed, and may begin to sweat. Rarely a fever may trigger a febrile seizure. This is more common in young children. Fevers do not typically go higher than . A fever can be caused by many medical conditions ranging from the not serious to potentially serious. This includes viral, bacterial and parasitic infections such as the common cold, urinary tract infections, meningitis, malaria and appendicitis among others. Non-infectious causes include vasculitis, deep vein thrombosis, side effects of medication, and cancer among others. It differs from hyperthermia, in that hyperthermia is an increase in body temperature over the temperature set-point, due to either too much heat production or not enough heat loss. Treatment to reduce fever is generally not required. Treatment of associated pain and inflammation, however, may be useful and help a person rest. Medications such as ibuprofen or paracetamol may help with this as well as lower temperature. Measures such as putting a cool damp cloth on the forehead and having a slightly warm bath are not useful and may simply make a person more uncomfortable. Children younger than three months require medical attention, as might people with serious medical problems such as a compromised immune system or people with other symptoms. Hyperthermia does require treatment. Fever is one of the most common medical signs. It is part of about 30% of healthcare visits by children and occurs in up to 75% of adults who are seriously sick. While fever is a useful defense mechanism,... - Antipyretics (from "anti-" 'against' and "" 'feverish') are substances that reduce fever. Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature. The body then works to lower the temperature, which results in a reduction in fever. - Phenicarbazide is a semicarbazide and an antipyretic substance . It is carcinogenic in mice . - Semicarbazide is the chemical compound with the formula OC(NH)(NH). It is a water-soluble white solid. It is a derivative of urea. After reading the paragraphs above, we are interested in knowing the entity with which 'phenicarbazide' exhibits the relationship of 'instance of'. Find the answer from the choices below.
