Answer the following question given this paragraph: Insects have a pair of antennae for "smelling" and "tasting" chemicals. Some insects can also use their antennae to detect sound. Other sensory organs on the head include several simple eyes and a pair of compound eyes. The compound eyes let insects see images. Butterflies and bees can even see in color. For feeding, the head contains one pair of mandibles and two pairs of maxillae . Insects consume a wide range of foods, and their mouthparts have become specialized. Several variations are shown in Figure below . Q: For feeding, the head contains one pair of mandibles and two pairs of what? Choices: - tracheae - antennae - chelicerae - maxillae A:
(A).
maxillae
Ques:Answer the following question given this paragraph: Most of the elements we know about do not exist freely in nature. Sodium cannot be found by itself (unless we prepare it in the laboratory) because it interacts easily with other materials. On the other hand, the element helium does not interact with other elements to any extent. We can isolate helium from natural gas during the process of drilling for oil. Q: Sodium is an example of what sort of thing that cannot exist by itself in nature? Choices: - concept - compound - aspect - element A:

Ans:element
