Answer the following question given this paragraph: Nuclear symbols are used to write nuclear equations for radioactive decay. Let's consider an example. Uranium-238 undergoes alpha decay to become thorium-234. (The numbers following the chemical names refer to the number of protons plus neutrons. ) In this reaction, uranium-238 loses two protons and two neutrons to become the element thorium-234. The reaction can be represented by this nuclear equation:. Q: What are used to write nuclear equations for radioactive decay? Choices: - special symbols - chemical symbols - energy symbols - nuclear symbols A:
(A).
nuclear symbols

Answer the following question given this paragraph: Animals are multicellular eukaryotes in the Animal Kingdom. All animals are heterotrophs. They eat other living things because they can't make their own food. All animals also have specialized cells that can do different jobs. Most animals have higher levels of organization as well. They may have specialized tissues, organs, and even organ systems. Having higher levels of organization allows animals to perform many complex functions.
