Q: Answer the following question given this paragraph: The drummer in Figure below is hitting the drumheads with drumsticks. This causes the drumheads to vibrate. The vibrations pass to surrounding air particles and then from one air particle to another in a wave of energy called sound energy . We hear sound when the sound waves reach our ears. Sound energy can travel through air, water, and other substances, but not through empty space. That's because the energy needs particles of matter to pass it on. Q: What energy, produced by vibrations, cannot travel through empty space? A:

OPTIONS:
- light
- heat
- plasma
- sound

A: sound

input: OPTIONS:
- life
- stomach
- fetal
- menstrual Now, answer this question: Answer the following question given this paragraph: Ovulation , the release of an egg from an ovary, is part of the menstrual cycle , which typically occurs each month in a sexually mature female unless she is pregnant. Another part of the cycle is the monthly period, or menstruation. Menstruation is the process in which the endometrium of the uterus is shed from the body. The menstrual cycle is controlled by hormones from the hypothalamus, pituitary gland, and ovaries. For an interactive animation of the menstrual cycle, you can go this link: http://health. howstuffworks. com/adam-200132. htm. Q: The release of an egg from an ovary, is part of what cycle? A:
A:
output: menstrual

Answer the following question given this paragraph: Haumea is the third-brightest Kuiper belt object. Haumea has two moons. Haumea's odd oval shape is probably caused by its extremely rapid rotation. It rotates in just less than 4 hours! Like other Kuiper belt objects, Haumea is covered by ice. Its density is similar to Earth's Moon, at 2.6 3.3 g/cm 3 . This means that most of Haumea is rocky. Q: Haumea, which is the third brightest kuiper belt object has an odd oval shape which is probably caused by what? A:

OPTIONS:
- unusually rapid rotation
- particularly rapid rotation
- Slow rotation
- extremely rapid rotation

Answer: extremely rapid rotation

Problem: OPTIONS:
- output
- voltage
- velocity
- current
Q: Answer the following question given this paragraph: Figure 20.2 The rate of flow of charge is current. An ampere is the flow of one coulomb through an area in one second. Q: The rate of flow of charge in an electrical circuit is known as what? A:
Answer: current

Problem:OPTIONS:
- protons
- positrons
- neutrons
- electrons

Answer the following question given this paragraph: How metalloids behave in chemical interactions with other elements depends mainly on the number of electrons in the outer energy level of their atoms. Metalloids have from three to six electrons in their outer energy level. Boron, pictured in the Figure below , is the only metalloid with just three electrons in its outer energy level. It tends to act like metals by giving up its electrons in chemical reactions. Metalloids with more than four electrons in their outer energy level (arsenic, antimony, and tellurium) tend to act like nonmetals by gaining electrons in chemical reactions. Those with exactly four electrons in their outer energy level (silicon and germanium) may act like either metals or nonmetals, depending on the other elements in the reaction. Q: How metalloids behave in chemical interactions with other elements depends mainly on the number of what, in the outer energy level of their atoms? A:
****
A: electrons

Problem:OPTIONS:
- fission
- Osmosis
- cytokinesis
- mitosis

Answer the following question given this paragraph: Mitosis in the Eukaryotic Cell Cycle. Mitosis is the multi-phase process in which the nucleus of a eukaryotic cell divides. Q: What is the multi-phase process in which the nucleus of a eukaryotic cell divides? A:
****
A:
mitosis
