This activity contains 11 questions.

	What is the correct order for the hierarchy of biological organization?   atom, molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem atom, molecule, cell, tissue, organelle, organ, organ system, organism, population, community, ecosystem atom, molecule, organelle, tissue, cell, organ, organ system, organism, population, community, ecosystem atom, molecule, organelle, cell, tissue, organ, organ system, organism, ecosystem, community, population atom, molecule, organelle, cell, tissue, organ, organ system, organism, population, ecosystem, community

	Which of these is an example of a population?   liver all of the grasses on a prairie a desert all of the red oak trees in a forest water

	Which of the following statements is true about chemical nutrients in an ecosystem?   They flow through the system, losing some nutrients in the process. They cycle within the ecosystem and are constantly reused. They can be converted to energy. They depend on sunlight as their source. They cannot be obtained from decomposition.

	Which domain includes multicellular photosynthetic organisms?   Bacteria Archaea Eukarya Fungi Protista

	Members of the domain Bacteria are more closely related to _____ than to _____.   Fungi … Plantae Fungi … Animalia Archaea … Monera Archaea … Fungi Protista … Archaea

	A property of life known as energy processing refers to the fact that living things _____.   can maintain constant internal conditions extract and store energy and materials from the environment can sense stimuli from the environment display heredity based on nucleic acids can reproduce

	When the human virus, HIV, first appeared, the mortality rate was close to 100%. However, recent information shows some individuals are unaffected and immune to the virus. Why?   The virus mutated through natural selection. New pharmaceutical medicines were produced that were more effective. A vaccination was developed and proved successful. Humans are genetically diverse, and some are immune to the virus. Individuals started to use protective measures more frequently.

	Drug-resistant tuberculosis is a major health issue in many countries. Treatment for these resistant forms of bacteria is longer and requires more expensive antibiotics. Scientists attribute this to natural selection. Under these circumstances, what does natural selection mean?   The antibiotic changed the DNA of the tuberculosis bacterium. Tuberculosis bacteria discovered a way to avoid these particular antibiotics. An environment was created in which the tuberculosis bacterium carrying the antibiotic-resistant genes could reproduce. The tuberculosis genes mutated to avoid being killed by the antibiotic. The mutation rate for the resistance to this particular antibiotic increased during a specific time period.

	What is the difference between inductive and deductive reasoning?   Inductions are testable; deductions are not testable. Inductive reasoning is used to develop testable hypotheses; deductive reasoning is used to derive general principles. "Human cells are similar to dog cells" is a statement that is derived from inductive reasoning. "All cells are fundamentally similar" is a statement derived from deductive reasoning. Inductive reasoning flows from the specific to the general; deductive reasoning flows from the general to the specific. Inductive reasoning, as a component of discovery science, is used to study the supernatural; deductive reasoning, as a component of hypothesis-driven science, is used to study the natural.

	To be of value to science, hypotheses must be _____.   established facts testable proven correct popular reproducible

	Identify the correct combination of positive and negative consequences from the use of more effective farming technologies.   more food, leads to fewer jobs more food, leads to overpopulation less food, leads to pollution less food, leads to fewer jobs
