Question: Q: What happens to energy in a closed system? Read this paragraph and choose the correct option from the provided answers: Energy is conserved in a closed system. That is, if you add up all the energy of an object(s) at one time it will equal all the energy of said object(s) at a later time. A closed system is a system where no energy is transferred in or out. The total energy of the universe is a constant (i. e. it does not change). The problems below do not consider the situation of energy transfer (called work). So friction and other sources where energy leaves the system are not present. Thus, one simply adds up all the potential energy and kinetic energy before and sets it equal to the addition of the total potential energy and kinetic energy after . Choices: - is replicated - is destroyed - is wasted - is conserved A:
Answer: is conserved

Question: Q: What type of mapping is critical for identifying the location of genes that cause genetic diseases? Read this paragraph and choose the correct option from the provided answers: Determining recombination frequencies between genes located on the same chromosome allows a linkage map to be developed. Linkage mapping is critical for identifying the location of genes that cause genetic diseases. Choices: - interaction mapping - diagnostic mapping - chemical mapping - linkage mapping A:
Answer: linkage mapping

Question: Q: What is the term for the use of radioactive decay to estimate the ages of fossils and rock? Read this paragraph and choose the correct option from the provided answers: Radioactive dating is the use of radioactive decay to estimate the ages of fossils and rocks. An example is carbon-14 dating. Choices: - isotope test - microwave theory - radioactive illustrating - radioactive dating A:
Answer:
radioactive dating
