Question: Q: What is the greatest contribution of arthropods to human food supply? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - vegetation - reproduction - hibernation - pollination A:
Answer: pollination

Question: Q: Which form of digestion is a purely physical process that does not change the chemical nature of the food? Read this paragraph and choose the correct option from the provided answers: Digestion includes both mechanical and chemical processes. Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with. Choices: - slow - simple - electromagnetic - mechanical A:
Answer: mechanical

Question: Q: Flatworms reproduce sexually. in most species, the same individuals produce both what? Read this paragraph and choose the correct option from the provided answers: Flatworms reproduce sexually. In most species, the same individuals produce both eggs and sperm. After fertilization occurs, the fertilized eggs pass out of the adult's body and hatch into larvae. There may be several different larval stages. The final larval stage develops into the adult form, and the life cycle repeats. Choices: - gametes - heart and sperm - diploid and haploid - eggs and sperm A:
Answer:
eggs and sperm
