Ques: Answer the following question given this paragraph: Some insects use siphoning, as if sucking through a straw, like moths and butterflies. This long mouth-tube that they use to suck up the nectar of the flower is called a proboscis . Some moths, however, have no mouthparts at all. Some insects obtain food by sponging , like the housefly. Sponging means that the mouthpart can absorb liquid food and send it to the esophagus. The housefly is able to eat solid food by releasing saliva and dabbing it over the food. As the saliva dissolves the food, the sponging mouthpart absorbs the liquid food. Q: The long mouth-tube that some insects use to suck up the nectar of the flower is called what? Choices: - stamen - prosthesis - pistil - proboscis A:
Ans: proboscis

Ques: Answer the following question given this paragraph: Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The chapter on atoms, molecules, and ions introduced the basic idea of nuclear structure, that the nucleus of an atom is composed of protons and, with the exception of 11 H, neutrons. Recall that the number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element. When referring to a single type of nucleus, we often use the term nuclide and identify it by the notation A where X is the symbol Z X, 14 Often a nuclide is referenced 6 C. example, 146 C is called "carbon-14. Q: Atoms with the same atomic number but different mass numbers are called what? Choices: - tropes - organisms - reactions - isotopes A:
Ans: isotopes
