Answer the following question given this paragraph: Q: Most taste buds on the tongue are associated with nipple-shaped projections called what? Choices: - antennae - mucosa - cilia - papillae A:
papillae
Answer the following question given this paragraph: 4. Molecular crystals -- Molecular crystals typically consist of molecules at the lattice points of the crystal, held together by relatively weak intermolecular forces (see Figure below ). The intermolecular forces may be dispersion forces in the case of nonpolar crystals, or dipole-dipole forces in the case of polar crystals. Some molecular crystals, such as ice, have molecules held together by hydrogen bonds. When one of the noble gases is cooled and solidified, the lattice points are individual atoms rather than molecules. In all cases, the intermolecular forces holding the particles together are far weaker than either ionic or covalent bonds. As a result, the melting and boiling points of molecular crystals are much lower. Lacking ions or free electrons, molecular crystals are poor electrical conductors. Q: What crystals consist of molecules at the lattice points of the crystal, held together by relatively weak intermolecular forces? Choices: - quartz crystals - salt crystals - healing crystals - molecular crystals A:
molecular crystals
Q: Answer the following question given this paragraph: Q: What are passed from one generation to the next so species can survive? Choices: - selections - mutations - fluctuations - adaptatioins A:
A: adaptatioins
Question: Answer the following question given this paragraph: There are approximately 160,000 living species and probably 70,000 extinct species of mollusks. They are typically divided into ten classes, of which two are extinct. The major classes of living mollusks include gastropods, bivalves, and cephalopods ( Figure below ). Q: The major classes of living members of this phylum include gastropods, bivalves, and cephalopods? Choices: - insects - crustaceans - invertebrates - mollusks A:
Answer: mollusks

Answer the following question given this paragraph: Torque is the turning effectiveness of a force. In this case, because F is perpendicular to r , torque is simply we multiply both sides of the equation above by r , we get torque on the left-hand side. That is, rF = mr 2. Q: What is the turning effectiveness of a force? Choices: - velocity - intake - gravitational pull - torque A:
**Answer**
torque

Answer the following question given this paragraph: Metallic solids are composed entirely of metallic atoms. In other solid structures, the electrons involved in bonding tend to be localized, or fixed in place in the covalent bonds. However, the electrons in metallic bonds are delocalized over the entire crystal. The fact that the electrons are free to move between different atoms causes metallic solids to be very good conductors of electricity. Q: Metallic solids are composed entirely of which atoms? Choices: - metals - organic - toxic - metallic A:
(A).
metallic
