Answer the following question given this paragraph: We see an opaque object, such as the apple in Figure below , because it reflects some wavelengths of visible light. The wavelengths that are reflected determine the color that the object appears. For example, the apple in the figure appears red because it reflects red light and absorbs light of other wavelengths. We see a transparent or translucent object, such as the bottle in Figure below , because it transmits light. The wavelength of the transmitted light determines the color that the object appears. For example, the bottle in the figure appears blue because it transmits blue light. Q: The color of an object is determined by the what of it's reflected light? Choices: - luminosity - variation - absorption - wavelength A:
wavelength

Answer the following question given this paragraph: A scuba diver, like the one in Figure below , releases air bubbles when he breathes under water. As he gets closer to the surface of the water, the air bubbles get bigger. Boyle's law explains why. The pressure of the water decreases as the diver gets closer to the surface. Because the bubbles are under less pressure, they increase in volume even though the amount of gas in the bubbles remains the same. Q: A diver's air bubbles increase in size as he approaches the surface because what decreases? Choices: - water direction - water weight - water energy - water pressure A:
(Answer)
water pressure
Ques: Answer the following question given this paragraph: the cell is the fundamental unit of structure and function in all living organisms,. Q: What is the fundamental unit of structure and function in all living organisms? Choices: - the spinal cord - the backbone - the vessels - the cell A:
Ans: the cell

Answer the following question given this paragraph: Plants maintain the atmosphere. They produce oxygen and absorb carbon dioxide during photosynthesis. Oxygen is essential for cellular respiration for all aerobic organisms. It also maintains the ozone layer that helps protect Earth's life from damaging UV radiation. Removal of carbon dioxide from the atmosphere reduces the greenhouse effect and global warming. Q: The ozone layer protects the earth from what? Choices: - pollution - light waves - radio waves - uv radiation A:
(A).
uv radiation
Ques:Answer the following question given this paragraph: Q: What gland secretes its products directly into the urethra through several small ducts Choices: - pituitary - adrenal - thyroid - prostate A:

Ans:prostate
Answer the following question given this paragraph: Acidophiles are organisms that "love" acids. They live in very acidic environments, such as acid mine drainage. They are also found near vents of volcanoes. The most acidophilic archaeans can thrive at negative pH values. No other organisms can survive in such acidic conditions. Q: Organisms that "love" acids are known as what? Choices: - acidophobes - acidic - acid heads - acidophiles A:
acidophiles
