Answer the following question given this paragraph: Mollusks are invertebrates such as snails, scallops, and squids. They have a hard outer shell. There is a layer of tissue called the mantle between the shell and the body. Most mollusks have tentacles for feeding and sensing, and many have a muscular foot. Mollusks also have a coelom, a complete digestive system, and specialized organs for excretion. The majority of mollusks live in the ocean. Different classes of mollusks have different ways of obtaining food. Q: Snails, scallops, and squids are what type of invertebrate? Choices: - crustacean - algae - arthropod - mollusk A:
mollusk
Answer the following question given this paragraph: A very important point here is that the vertical motion of these two balls is identical. That is, they each fall exactly the same distance vertically in each succeeding second. The constant horizontal velocity of the blue ball has no effect on its accelerated vertical motion. Therefore, the vertical motion of the blue ball can be analyzed exactly the same as the vertical motion of the red ball. Q: What force pulls bodies with mass together? Choices: - thermal - solar - isolation - gravity A:
gravity
Q: Answer the following question given this paragraph: A: You can see that snow and sand have a different color. You can also feel that snow is softer than sand. Both color and hardness are physical properties of matter. Q: What are color and hardness physical properties of? Choices: - cells - ions - elements - matter A:
A: matter
Question: Answer the following question given this paragraph: Nitrogen Fixation: Root and Bacteria Interactions Nitrogen is an important macronutrient because it is part of nucleic acids and proteins. Atmospheric nitrogen, which is the diatomic molecule N2, or dinitrogen, is the largest pool of nitrogen in terrestrial ecosystems. However, plants cannot take advantage of this nitrogen because they do not have the necessary enzymes to convert it into biologically useful forms. However, nitrogen can be "fixed," which means that it can be converted to ammonia (NH3) through biological, physical, or chemical processes. As you have learned, biological nitrogen fixation (BNF) is the conversion of atmospheric nitrogen (N2) into ammonia (NH3), exclusively carried out by prokaryotes such as soil bacteria or cyanobacteria. Biological processes contribute 65 percent of the nitrogen used in agriculture. The following equation represents the process:. Q: Nitrogen is an important macronutrient because it is part of nucleic acids and proteins. atmospheric nitrogen, which is the diatomic molecule n2, or dinitrogen, is the largest pool of nitrogen in these? Choices: - gas planets - desert biomes - aquatic ecosytems - terrestrial ecosystems A:
Answer: terrestrial ecosystems
