Q: Answer the following question given this paragraph: In addition, endocrine signaling is typically less specific than neural signaling. The same hormone may play a role in a variety of different physiological processes depending on the target cells involved. For example, the hormone oxytocin promotes uterine contractions in women in labor. It is also important in breastfeeding, and may be involved in the sexual response and in feelings of emotional attachment in both males and females. In general, the nervous system involves quick responses to rapid changes in the external environment, and the endocrine system is usually slower actingtaking care of the internal environment of the body, maintaining homeostasis, and controlling reproduction (Table 17.1). So how does the fight-or-flight response that was mentioned earlier happen so quickly if hormones are usually slower acting? It is because the two systems are connected. It is the fast action of the nervous system in response to the danger in the environment that stimulates the adrenal glands to secrete their hormones. As a result, the nervous system can cause rapid endocrine responses to keep up with sudden changes in both the external and internal environments when necessary. Q: Which system is capable of responding quickly to changing situations? A:

OPTIONS:
- endocrine system
- reproductive system
- circulatory system
- nervous system

A: nervous system

input: OPTIONS:
- explode
- erode
- transform
- solidify Now, answer this question: Answer the following question given this paragraph: Start right above point on the temperature axis and follow the red line vertically. At very low pressure, the particles of the substance are far apart from one another and the substance is in the gas state. As the pressure is increased, the particles of the substance are forced closer and closer together. Eventually the particles are pushed so close together that attractive forces cause the substance to condense into the liquid state. Continually increasing the pressure on the liquid will eventually cause the substance to solidify. For the majority of substances, the solid state is denser than the liquid state and so putting a liquid under great pressure will cause it to turn into a solid. The line segment represents the process of sublimation, where the substance changes directly from a solid to a gas. At a sufficiently low pressure, the liquid phase does not exist. The point labeled is called the triple point . The triple point is the one condition of temperature and pressure where the solid, liquid, and vapor states of a substance can all coexist at equilibrium. Q: Continually increasing the pressure on the liquid will eventually cause the substance to do what? A:
A:
output: solidify

Answer the following question given this paragraph: Fungi can grow fast because they are such good eaters. Fungi have lots of surface area, and this large surface area "eats" or absorbs. Surface area is how much exposed area an organism has, compared to their overall volume. Most of a mushroom's surface area is actually underground. If you see a mushroom in your yard, that is just a small part of a larger fungus growing underground. Q: Most of a mushroom's surface area is actually where? A:

OPTIONS:
- hidden
- underwater
- air
- underground

Answer: underground

Problem: OPTIONS:
- contains alloys
- a single state of matter
- bonds easily
- three different states of matter
Q: Answer the following question given this paragraph: The halogen group is quite diverse. It includes elements that occur in three different states of matter at room temperature. Fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. Halogens also vary in color, as you can see in the Figure below . Fluorine and chlorine are green, bromine is red, and iodine and astatine are nearly black. Like other nonmetals, halogens cannot conduct electricity or heat. Compared with most other elements, halogens have relatively low melting and boiling points. You can watch a lab demonstration of the melting and boiling points of halogens at this URL: http://www. youtube. com/watch?v=yP0U5rGWqdg . Q: What makes the halogen group so diverse? A:
Answer: three different states of matter

Problem:OPTIONS:
- depth
- stretch
- portion
- length

Answer the following question given this paragraph: Length is the measurement of the extent of something along its greatest dimension. The SI basic unit of length, or linear measure, is the meter (m). All measurements of length may be made in meters, though the prefixes listed in various tables will often be more convenient. The width of a room may be expressed as about 5 meters (m), whereas a large distance, such as the distance between New York City and Chicago, is better expressed as 1150 kilometers (km). Very small distances can be expressed in units such as the millimeter or the micrometer. The width of a typical human hair is about 20 micrometers (m). Q: The measurement of the extent of something along its greatest dimension is its what? A:
****
A: length

Problem:OPTIONS:
- wood
- shale
- coal
- soil

Answer the following question given this paragraph: Earthworms are important deposit feeders that help form and enrich soil. Q: Earthworms are important deposit feeders that help form and enrich what material? A:
****
A:
soil
