Question: Q: A refrigerator must do work to reverse the normal direction of what? Read this paragraph and choose the correct option from the provided answers: A refrigerator must do work to reverse the normal direction of thermal energy flow. Work involves the use of force to move something, and doing work takes energy. In a refrigerator, the energy is usually provided by electricity. You can read in detail in the Figure below how a refrigerator does its work. For an animation of how a refrigerator works, go to this URL: http://www. chemistry. wustl. edu/~edudev/LabTutorials/CourseTutorials/LabTutorials/Thermochem/fridge_movie. html. Choices: - visible energy flow - coolant energy flow - spectral energy flow - thermal energy flow A:
Answer: thermal energy flow

Q: Our digestive system breaks down starch to what? Read this paragraph and choose the correct option from the provided answers: Starches are complex carbohydrates. They are polymers of glucose. They consist of hundreds of glucose monomers bonded together. Plants make starch to store extra sugars. Consumers get starch from plants. Common sources of starch in the human diet are pictured in Figure below . Our digestive system breaks down starch to simple sugars, which our cells use for energy. Choices: - Salts - Waste - pattern sugars - simple sugars A:
**Answer**
simple sugars

(Q).
Q: Which phylum are all vertebrate organisms a member of? Read this paragraph and choose the correct option from the provided answers: All vertebrate organisms are in the phylum Chordata. Invertebrates, which make up about 95% (or more) of the animal kingdom, are divided into over 30 different phyla, some of which are listed below ( Table below ). Numerous invertebrate phyla have just a few species; some have only one described species, yet these are classified into separate phyla because of their unique characteristics. For example, sponges, with pores throughout their body, are from the phylum Porifera. Crabs and lobsters, with jointed appendages, are from the phylum Arthropoda. Choices: - pylum protozoa - phylum hominid - phylum arthropod - phylum chordata A:
(A).
phylum chordata
