Answer the following question given this paragraph: Oceanography is the study of the oceans. The word oceanology might be more accurate, since "ology" is "the study of. " "Graph" is "to write" and refers to mapmaking. But mapping the oceans is how oceanography started. Q: What is oceanography the study of? Choices: - bodies of water - seas - waters - oceans A:
oceans
Answer the following question given this paragraph: The law of conservation of energy states that matter cannot be created or destroyed. Whether a chemical reaction absorbs or releases energy, there is no overall change in the amount of energy during the reaction. Q: What law states that matter cannot be created or destroyed? Choices: - Murphy's Law - law of inertia - construct of energy - conservation of energy A:
conservation of energy
Q: Answer the following question given this paragraph: Both conduction and convection transfer energy through matter. Radiation is the only way of transferring energy that doesn't require matter. Radiation is the transfer of energy by waves that can travel through empty space. When the waves reach objects, they transfer energy to the objects, causing them to warm up. This is how the sun's energy reaches Earth and heats its surface (see Figure below ). Radiation is also how thermal energy from a campfire warms people nearby. You might be surprised to learn that all objects radiate thermal energy, including people. In fact, when a room is full of people, it may feel noticeably warmer because of all the thermal energy the people radiate! To learn more about thermal radiation, watch "Radiation" at the URL below. Q: What is the only way of transferring energy that doesn't require matter? Choices: - mutation - evaporation - convection - radiation A:
A: radiation
Question: Answer the following question given this paragraph: The female reproductive system consists of structures that produce eggs and secrete female sex hormones. They also provide a site for fertilization and enable the development and birth of a fetus. They include the vagina, uterus, ovaries, and fallopian tubes. Q: What consists of structures that produce eggs and secrete female sex hormones? Choices: - male reproductive system - female neural system - asexual reproductive system - female reproductive system A:
Answer: female reproductive system

Answer the following question given this paragraph: VII *The convention of using roman numerals to indicate the oxidation states of a metal is used here. Binary transition-metal compounds, such as the oxides and sulfides, are usually written with idealized stoichiometries, such as FeO or FeS, but these compounds are usually cation deficient and almost never contain a 1:1 cation:anion ratio. Thus a substance such as ferrous oxide is actually a nonstoichiometric compound with a range of compositions. The acidbase character of transition-metal oxides depends strongly on the oxidation state of the metal and its ionic radius. Oxides of metals in lower oxidation states (less than or equal to +3) have significant ionic character and tend to be basic. Conversely, oxides of metals in higher oxidation states are more covalent and tend to be acidic, often dissolving in strong base to form oxoanions. Q: Binary transition-metal compounds, such as the oxides and sulfides, are usually written with idealized what? Choices: - speciation - fluctuations - noble gases - stoichiometries A:
**Answer**
stoichiometries
Q: Answer the following question given this paragraph: Two natural products of mollusks used for decorations and jewelry are pearls and nacre. A pearl is the hard, round object produced within the mantle of a living shelled mollusk. Pearls are produced by many bivalves when a tiny particle of sand or grit is trapped between the mantle and the shell. It's as if the mollusk has a splinter. The mollusk forms a protective covering around the irritant. Most pearls used as jewelry are made by pearl oysters and freshwater mussels; most of the ones sold are cultured and not wild. Natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Q: What is the term for the hard, round object produced within the mantle of a living shelled mollusk? Choices: - ball - root - glass - pearl A:
A: pearl
