Answer the following question given this paragraph: When atomic orbitals hybridize, the valence electrons occupy the newly created orbitals. The Be atom had two valence electrons, so each of the sp orbitals gets one of these electrons. Each of these electrons pairs up with the unpaired electron on a chlorine atom when a hybrid orbital and a chlorine orbital overlap during the formation of the BeCl bonds. Q: When atomic orbitals hybridize, the valence electrons occupy these? Choices: - newly created elements - newly developed orbits - expanded pathways - newly created orbitals A:
newly created orbitals
Answer the following question given this paragraph: Reconnection After speciation, two species may recombine or even continue interacting indefinitely. Individual organisms will mate with any nearby individual who they are capable of breeding with. An area where two closely related species continue to interact and reproduce, forming hybrids, is called a hybrid zone. Over time, the hybrid zone may change depending on the fitness of the hybrids and the reproductive barriers (Figure 18.22). If the hybrids are less fit than the parents, reinforcement of speciation occurs, and the species continue to diverge until they can no longer mate and produce viable offspring. If reproductive barriers weaken, fusion occurs and the two species become one. Barriers remain the same if hybrids are fit and reproductive: stability may occur and hybridization continues. Q: What term means an area where two closely related species continue to interact and reproduce? Choices: - homozone - heterozone - common zone - hybrid zone A:
hybrid zone
Q: Answer the following question given this paragraph: human body system that includes all the muscles of the body. Q: Compound light microscopes use lenses to do what? Choices: - stop light - twist light - burn light - focus light A:
A: focus light
Question: Answer the following question given this paragraph: The human eye can distinguish only red, green, and blue light. These three colors are called the primary colors of light. All other colors of light can be created by combining the primary colors. Look at the Venn diagram below . Red and green light combine to form yellow light. Red and blue light combine to form magenta light, and blue and green light combine to form cyan light. Yellow, magenta, and cyan are called the secondary colors of light. Look at the center of the diagram, where all three primary colors of light combine. The result is white light. You can explore the colors of visible light and how they combine at this URL: http://www. phy. ntnu. edu. tw/oldjava/color/color_e. html. Q: Which three colors are called the primary colors of light? Choices: - red, blue, yellow - black, white, red - blue, green, violet - red, green, blue A:
Answer: red, green, blue

Answer the following question given this paragraph: Mineralogists are scientists who study minerals. They divide minerals into groups based on chemical composition. Even though there are over 4,000 minerals, most minerals fit into one of eight mineral groups. Minerals with similar crystal structures are grouped together. Q: Similarity of crystal structures is used to categorize what non-living materials? Choices: - salts - corals - grains - minerals A:
**Answer**
minerals

Answer the following question given this paragraph: A circuit that consists of two loops is called a parallel circuit. If one loop of a parallel circuit is interrupted, current can still flow through the other loop. Q: A circuit that consists of two loops is called a what? Choices: - diverse circuit - unnatural circuit - complex circuit - parallel circuit A:
(Answer)
parallel circuit
