Answer the following question given this paragraph: synostoses and fusing the bony components together into the single hip bone of the adult. Similarly, synostoses unite the sacral vertebrae that fuse together to form the adult sacrum. Q: Synostoses unite the sacral vertebrae that fuse together to form the what? Choices: - young sacrum - lower sacrum - permanent sacrum - adult sacrum A:
adult sacrum
Answer the following question given this paragraph: Mirrors are made from highly reflective metal that is applied to a curved or flat piece of glass. Converging mirrors can be used to focus light headlights, telescopes, satellite TV receivers, and solar cookers all rely on this principle. Q: What are made from highly reflective metal that is applied to a curved or flat piece of glass? Choices: - lenses - kaleidoscopes - prisms - mirrors A:
mirrors
Q: Answer the following question given this paragraph: The Zygote Recall that at the point of fertilization, the oocyte has not yet completed meiosis; all secondary oocytes remain arrested in metaphase of meiosis II until fertilization. Only upon fertilization does the oocyte complete meiosis. The unneeded complement of genetic material that results is stored in a second polar body that is eventually ejected. At this moment, the oocyte has become an ovum, the female haploid gamete. The two haploid nuclei derived from the sperm and oocyte and contained within the egg are referred to as pronuclei. They decondense, expand, and replicate their DNA in preparation for mitosis. The pronuclei then migrate toward each other, their nuclear envelopes disintegrate, and the male- and femalederived genetic material intermingles. This step completes the process of fertilization and results in a single-celled diploid zygote with all the genetic instructions it needs to develop into a human. Most of the time, a woman releases a single egg during an ovulation cycle. However, in approximately 1 percent of ovulation cycles, two eggs are released and both are fertilized. Two zygotes form, implant, and develop, resulting in the. Q: During the typical human female ovulation cycles, how many eggs are released? Choices: - four - two - three - one A:
A: one
Question: Answer the following question given this paragraph: The name electric current is the name given to the phenomenon that occurs when an electric field moves down a wire at close to the speed of light. Voltage is the electrical energy density that causes the electric current. Resistance is the amount a device in the wire resists the flow of current by converting electrical energy into other forms of energy. A device, the resistor, could be a light bulb, transferring electrical energy into heat and light or an electric motor that converts electric energy into mechanical energy. The difference in Voltage across a resistor or other electrical device is called the voltage drop. Q: What is the difference in voltage across a resistor or other electrical devices called? Choices: - volt effect - falling voltage - power drop - voltage drop A:
Answer: voltage drop

Answer the following question given this paragraph: Replacement reactions occur when elements switch places in compounds. In a single replacement reaction, one element takes the place of another in a single compound. In a double replacement reaction, two compounds exchange elements. Q: What occur when elements switch places in compounds? Choices: - chemical interaction - chain reaction - chemical reaction - replacement reactions A:
**Answer**
replacement reactions
