Answer the following question given this paragraph: The sun and other stars produce light because they are so hot. They glow with light due to their extremely high temperatures. This way of producing light is called incandescence . Some objects produce light without becoming very hot. They generate light through chemical reactions or other processes. Producing light without heat is called luminescence . Objects that produce light by luminescence are said to be luminous. Luminescence, in turn, can occur in different ways:. Q: Producing light without heat is called what? Choices: - osmosis - thermoluminescence - bioluminescence - luminescence A:
luminescence
Answer the following question given this paragraph: Aflatoxins are toxic, carcinogenic compounds released by fungi of the genus Aspergillus. Periodically, harvests of nuts and grains are tainted by aflatoxins, leading to massive recall of produce. This sometimes ruins producers and causes food shortages in developing countries. Q: Aflatoxins are toxic, carcinogenic compounds released by fungi of this? Choices: - protist group - genus sporozoa - arthropod class - genus aspergillus A:
genus aspergillus
Q: Answer the following question given this paragraph: Imagine now that you have a second cup with 100ml of water, and you add 45 grams of table sugar to the water. Just like the first cup, the sugar is the solute, and the water is the solvent. But now you have two mixtures of different solute concentrations. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic , and the solution with the lower solute concentration is hypotonic . Solutions of equal solute concentration are isotonic . The first sugar solution is hypotonic to the second solution. The second sugar solution is hypertonic to the first. Q: In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is called what? Choices: - acetic - hypothermic - hydrophilic - hypertonic A:
A: hypertonic
Question: Answer the following question given this paragraph: Ocean currents carry warm or cold water throughout the world's oceans. They help to even out the temperatures in the oceans. This also affects the temperature of the atmosphere and the climate around the world. Currents that are near shore have a direct impact on climate. They may make the climate much colder or warmer. You can see examples of this in Figure below . Q: What carries warm or cold water throughout the world's oceans? Choices: - gravity - pipes - earth rotation - ocean currents A:
Answer: ocean currents
