Answer the following question given this paragraph: A chain of volcanoes form as an oceanic plate moves over a hotspot. This is how it happens. A volcano forms over the hotspot. Since the plate is moving, the volcano moves off of the hotspot. When the hotspot erupts again, a new volcano forms over it. This volcano is next to the first. Over time, there is a line of volcanoes. The youngest is directly above the hotspot. The oldest is the farthest away ( Figure below ). Q: A chain of what structures form as an oceanic plate moves over a hotspot? Choices: - ridges - earthquakes - outcrops - volcanoes A:
volcanoes
Answer the following question given this paragraph: Courtesy of the U. S. National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) Program. Lymph capillaries collect the flood the leaks from blood capillaries and is slowly returned to the cardiovascular system . Q: Lymph capillaries collect the fluid that leaks from blood capillaries and slowly return it to what system? Choices: - muscular - circulatory - gastrointestinal - cardiovascular A:
cardiovascular
Q: Answer the following question given this paragraph: Figure 6.3 A cell moves through a series of phases in an orderly manner. During interphase, G1 involves cell growth and protein synthesis, the S phase involves DNA replication and the replication of the centrosome, and G2 involves further growth and protein synthesis. The mitotic phase follows interphase. Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into daughter nuclei. Usually the cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed. Q: Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into what? Choices: - father nuclei - long nuclei - woman nuclei - daughter nuclei A:
A: daughter nuclei
Question: Answer the following question given this paragraph: The name silicon dioxide implies one silicon atom and two oxygen atoms, so the formula is SiO2. We have a name that has numerical prefixes on both elements. Tri- means three, and tetrameans four, so the formula of this compound is Si3N4. Q: How many atoms of oxygen does silicon dioxide contain? Choices: - three - six - one - two A:
Answer: two

Answer the following question given this paragraph: A: When air temperature reaches the dew point, water vapor starts condensing. It may form dew (as on the spider web in the opening image), clouds, or fog. Dew forms on solid objects on the ground. Clouds form on tiny particles in the air high above the ground. Fog is a cloud that forms on tiny particles in the air close to the ground. Q: When the air temperature reaches the dew point, water vapor starts to do what? Choices: - evaporate - germinate - dissipate - condense A:
**Answer**
condense
Q: Answer the following question given this paragraph: Birth Prior to birth, the lungs are filled with amniotic fluid, mucus, and surfactant. As the fetus is squeezed through the birth canal, the fetal thoracic cavity is compressed, expelling much of this fluid. Some fluid remains, however, but is rapidly absorbed by the body shortly after birth. The first inhalation occurs within 10 seconds after birth and not only serves as the first inspiration, but also acts to inflate the lungs. Pulmonary surfactant is critical for inflation to occur, as it reduces the surface tension of the alveoli. Preterm birth around 26 weeks frequently results in severe respiratory distress, although with current medical advancements, some babies may survive. Prior to 26 weeks, sufficient pulmonary surfactant is not produced, and the surfaces for gas exchange have not formed adequately; therefore, survival is low. Q: Prior to birth, the lungs are filled with amniotic fluid, mucus, and what else? Choices: - blood - plasma - air - surfactant A:
A: surfactant
