Answer the following question given this paragraph: How often do you think you see an arthropod? Well, have you ever looked up close at an ant? A spider? A fly? A moth? With over a million described species (and many more yet to be described) in the phylum containing arthropods, chances are, you encounter one of these organisms every day, without even leaving your house. Arthropods are a very diverse group of animals. In fact, they are the biggest group of animals on the planet, with upwards of 5 million distinct species. Q: What is the biggest group of animals on the planet? Choices: - herbivores - mammles - carnivores - arthropods A:
arthropods
Q: Answer the following question given this paragraph: Biomes as different as deserts and wetlands share something very important. All biomes have populations of interacting species. Species interact in the same basic ways in all biomes. For example, all biomes have some species that prey on others for food. Q: Although they are as different as deserts and wetlands, all of these ecosystem units have populations of interacting species? Choices: - corals - continents - zoos - biomes A:
A: biomes
Question: Answer the following question given this paragraph: Q: What are all tissues external to the vascular cambium called? Choices: - nucleus - membranes - larvae - bark A:
Answer: bark

Answer the following question given this paragraph: Living chordates are mainly vertebrates. In vertebrates, the notochord develops into a backbone, or vertebral column, after the embryonic stage. A small percentage of chordates are invertebrates. Their notochord never develops into a backbone. Invertebrate chordates include tunicates and lancelets. Both groups of animals are small and relatively primitive. They are probably similar to the earliest chordates that evolved more than 500 million years ago. Q: During the embryonic stage of vertebrates, the notochord develops into what? Choices: - rib cage - umbilical cord - brain stem - backbone A:
**Answer**
backbone
Answer the following question given this paragraph: There are other forms of radioactive dating. Rocks, for example, can sometimes be dated based on the decay of 238 U . The decay series for 238 U ends with 206 Pb , so that the ratio of these nuclides in a rock is an indication of how long it has been since the rock solidified. The original composition of the rock, such as the absence of lead, must be known with some confidence. However, as with carbon-14 dating, the technique can be verified by a consistent body of knowledge. Since 238 U has a half-life of solidified about. Q: What is the term for dating a rock based on composition decay? Choices: - carbon dating - fuel dating - safe dating - radioactive dating A:
radioactive dating
