Answer the following question given this paragraph: Rocks can break apart into smaller pieces in many ways. Ice wedging is common where water goes above and below its freezing point ( Figure below ). This can happen in winter in the mid-latitudes or in colder climates in summer. Ice wedging is common in mountainous regions like the Sierra Nevada pictured above. Q: When water goes above and below its freezing point, what rock-breaking phenomenon is common? Choices: - ice locking - ice inverting - ice crushing - ice wedging A:
ice wedging
Q: Answer the following question given this paragraph: Q: Dispersal occurs only on what time scale? Choices: - regular - conventional - developmental - evolutionary A:
A: evolutionary

The most common orders include landfowl, waterfowl, shorebirds, diurnal and nocturnal raptors, parrots, and perching birds. Q: How many orders can flying birds be divided into? Choices: - 31 - 44 - 19 - 29 A:
Answer: 29

Answer the following question given this paragraph: Unlike that of the Hexapoda, the head and thorax of most crustaceans is fused to form a cephalothorax (Figure 28.40), which is covered by a plate called the carapace, thus producing a body structure of two tagma. Crustaceans have a chitinous exoskeleton that is shed by molting whenever the animal increases in size. The exoskeletons of many species are also infused with calcium carbonate, which makes them even stronger than in other arthropods. Crustaceans have an open circulatory system where blood is pumped into the hemocoel by the dorsally located heart. Hemocyanin and hemoglobin are the respiratory pigments present in these animals. Q: In most crustaceans, what two structures fuse to form a cephalothorax? Choices: - foot and toes - body and shoulders - wing and legs - head and thorax A:
**Answer**
head and thorax

Answer the following question given this paragraph: In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, a simple way of representing those valence electrons would be useful. A Lewis electron dot diagram (or electron dot diagram or a Lewis diagram or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom. These dots are arranged to the right and left and above and below the symbol, with no more than two dots on a side. (It does not matter what order the positions are used. ) For example, the Lewis electron dot diagram for hydrogen is simply. Q: What is a representation of the valence electrons of an atom that uses dots around the symbol of the element? Choices: - watson structure - right structure - time structure - lewis structure A:
(Answer)
lewis structure
