Answer the following question given this paragraph: Yeasts do not produce spores. Instead, they reproduce asexually by budding. Budding is the pinching off of an offspring from the parent cell. The offspring cell is genetically identical to the parent. Budding in yeast is pictured in Figure below . Q: How do yeasts reproduce asexually? Choices: - by outcropping - by merging - by synchronizing - by budding A:
by budding
Answer the following question given this paragraph: The atmosphere is a big part of the water cycle. What do you think would happen to Earth's water without it?. Q: What is the upper-most atmosphere known as? Choices: - xerosphere - exosphere - ionosphere - thermosphere A:
thermosphere
Q: Answer the following question given this paragraph: 18.1 How Animals Reproduce Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring. Asexual reproduction in animals occurs through fission, budding, fragmentation, and parthenogenesis. Sexual reproduction may involve fertilization inside the body or in the external environment. A species may have separate sexes or combined sexes; when the sexes are combined they may be expressed at different times in the life cycle. The sex of an individual may be determined by various chromosomal systems or environmental factors such as temperature. Sexual reproduction starts with the combination of a sperm and an egg in a process called fertilization. This can occur either outside the bodies or inside the female. The method of fertilization varies among animals. Some species release the egg and sperm into the environment, some species retain the egg and receive the sperm into the female body and then expel the developing embryo covered with shell, while still other species retain the developing offspring throughout the gestation period. Q: What type of reproduction begins when an egg and sperm combine? Choices: - natural reproduction - regular reproduction - asexual reproduction - sexual reproduction A:
A: sexual reproduction
Question: Answer the following question given this paragraph: The bacteria that make food from chemicals are also primary producers. These organisms do not do photosynthesis since there is no light at the vents. They do something called chemosynthesis. They break down chemicals to make food. Q: What is the process bacteria use to break down chemicals into food? Choices: - biosynthesis - gametogenesis - cellular respiration - chemosynthesis A:
Answer: chemosynthesis

**Answer**
glycolysis

Answer the following question given this paragraph: (b) Write a balanced chemical equation showing the products of the dissolution of Fe(NO3)3. Compare the processes that occur when methanol (CH3OH), hydrogen chloride (HCl), and sodium hydroxide (NaOH) dissolve in water. Write equations and prepare sketches showing the form in which each of these compounds is present in its respective solution. What is the expected electrical conductivity of the following solutions? (a) NaOH(aq) (b) HCl(aq) (c) C6H12O6(aq) (glucose) (d) NH3(l) 14. Why are most solid ionic compounds electrically nonconductive, whereas aqueous solutions of ionic compounds are good conductors? Would you expect a liquid (molten) ionic compound to be electrically conductive or nonconductive? Explain. Indicate the most important type of intermolecular attraction responsible for solvation in each of the following solutions: (a) the solutions in Figure 11.8 (b) methanol, CH3OH, dissolved in ethanol, C2H5OH (c) methane, CH4, dissolved in benzene, C6H6 (d) the polar halocarbon CF2Cl2 dissolved in the polar halocarbon CF2ClCFCl2 (e) O2(l) in N2(l) 11.3 Solubility 16. Suppose you are presented with a clear solution of sodium thiosulfate, Na2S2O3. How could you determine whether the solution is unsaturated, saturated, or supersaturated? 17. Supersaturated solutions of most solids in water are prepared by cooling saturated solutions. Supersaturated solutions of most gases in water are prepared by heating saturated solutions. Explain the reasons for the difference in the two procedures. Suggest an explanation for the observations that ethanol, C2H5OH, is completely miscible with water and that ethanethiol, C2H5SH, is soluble only to the extent of 1.5 g per 100 mL of water. Calculate the percent by mass of KBr in a saturated solution of KBr in water at 10 C. See Figure 11.17 for useful data, and report the computed percentage to one significant digit. Which of the following gases is expected to be most soluble in water? Explain your reasoning. (a) CH4 (b) CCl4. Q: Supersaturated solutions of most solids in water are prepared by cooling what? Choices: - mineral solutions - dense solutions - plasma solutions - saturated solutions A:
**Answer**
saturated solutions
