(Question)
Answer the following question given this paragraph: All of these animal behaviors are important. They help the animals get food for energy, make sure their young survive, or ensure that they, themselves, survive. Behaviors that help animals or their young survive, increase the animals' fitness. Animals with higher fitness have a better chance of passing their genes on to the next generation. If genes control behaviors that increase fitness, the behaviors become more common in the species. This occurs through the process of evolution by natural selection. Q: Fitness and natural selection are parts of what theory that might describe how organisms change over time? Choices: - dessication - gravity - implementation - evolution A:
(Answer)
evolution

(Question)
Answer the following question given this paragraph: Evolution means change over time. Darwin's theory of evolution says that organisms change over time ( Figure below ). Evolution is seen in the fossil record. It is seen in the way organisms develop. Evolution is evident in the geographic locations where organism are found. It is evident in the genes of living organisms. Evolution has a mechanism called natural selection . The organism that is best suited to its environment is most likely to survive. Evolution is described in the chapter Life on Earth . Q: Organism's changing over time is called? Choices: - generation - heterogenicity - variation - evolution A:
(Answer)
evolution

(Question)
Answer the following question given this paragraph: The intentional cultivation of arthropods and other small animals for human food, referred to as minilivestock, is now emerging in animal husbandry as an ecologically sound concept. However, the greatest contribution of arthropods to human food supply is by pollination. Three-fourths of the world's flowering plants and about 35% of the world's food crops depend on animal pollinators to reproduce and increase crop yields. More than 3,500 species of native bees pollinate crops. Some scientists estimate that one out of every three bites of food we eat exists because of animal pollinators, including birds and bats and arthropods like bees, butterflies and moths, and beetles and other insects. Q: What is the greatest contribution of arthropods to human food supply? Choices: - vegetation - reproduction - hibernation - pollination A:
(Answer)
pollination
