Answer the following question given this paragraph: Objects in motion that return to the same position after a fixed period of time are said to be in harmonic motion. Objects in harmonic motion have the ability to transfer some of their energy over large distances. They do so by creating waves in a medium. Imagine pushing up and down on the surface of a bathtub filled with water. Water acts as the medium that carries energy from your hand to the edges of the bathtub. Waves transfer energy over a distance without direct contact with the initial source. Since waves are disturbances in an existing medium, they are considered phenomena and not actual objects. Q: Objects in motion that return to the same position after a fixed period of time are said to be in what? Choices: - resonant motion - kinetic motion - homeostasis - harmonic motion A:
harmonic motion
Answer the following question given this paragraph: 7. People with red hair usually have very light skin. What might be a genetic explanation for this observation?. Q: People with red hair usually have what type of skin? Choices: - dark - oily - dry - light A:
light
Q: Answer the following question given this paragraph: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide, and large amounts of corrosive sulfuric acid! Scientists think the color of sunlight on Venus is reddish-brown. Q: What are clouds on earth made of? Choices: - rain - ozone - carbon dioxide gas - water vapor A:
A: water vapor
Question: Answer the following question given this paragraph: The Epithelial Cell Epithelial cells are typically characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces. Particular structures found in some epithelial cells are an adaptation to specific functions. Certain organelles are segregated to the basal sides, whereas other organelles and extensions, such as cilia, when present, are on the apical surface. Cilia are microscopic extensions of the apical cell membrane that are supported by microtubules. They beat in unison and move fluids as well as trapped particles. Ciliated epithelium lines the ventricles of the brain where it helps circulate the cerebrospinal fluid. The ciliated epithelium of your airway forms a mucociliary escalator that sweeps particles of dust and pathogens trapped in the secreted mucous toward the throat. It is called an escalator because it continuously pushes mucous with trapped particles upward. In contrast, nasal cilia sweep the mucous blanket down towards your throat. In both cases, the transported materials are usually swallowed, and end up in the acidic environment of your stomach. Q: What cells are typically characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces? Choices: - mast cells - nerve cells - connective tissue - epithelial cells A:
Answer: epithelial cells

Answer the following question given this paragraph: Water on Mars can't be a liquid. This is because the pressure of the atmosphere is too low. The planet does have a lot of water; it is in the form of ice. The south pole of Mars has a very visible ice cap. Scientists also have evidence that there is also a lot of ice just under the Martian surface. The ice melts when volcanoes erupt. At this times liquid water flows across the surface. Q: What form does water take on the planet mars? Choices: - plasma - gas - liquid - ice A:
**Answer**
ice
Q: Answer the following question given this paragraph: Earth's gravity also affects the acceleration of objects that start out moving horizontally, or parallel to the ground. Look at Figure below . A cannon shoots a cannon ball straight ahead, giving the ball horizontal motion. At the same time, gravity pulls the ball down toward the ground. Both forces acting together cause the ball to move in a curved path. This is called projectile motion . Q: Which factor causes a cannon ball to move horizontally and then fall on the ground? Choices: - cone motion - fluid motion - downward motion - projectile motion A:
A: projectile motion
