Answer the following question given this paragraph: In warmer regions, plants and bacteria grow faster. Plants and animals weather material and produce soils. In tropical regions, where temperature and precipitation are consistently high, thick soils form. Arid regions have thin soils. Q: What happens to growth of plants and bacteria in warmer regions? A:
****
A: they grow faster

Answer the following question given this paragraph: Radiocarbon is useful for relatively young, carbon-based materials. Other longer-lived isotopes are good for older rocks and minerals. Q: Radiocarbon is useful for dating relatively young materials with what element as their base? A:
OPTIONS:
- hydrogen
- oxygen
- nitrogen
- carbon
carbon

Answer the following question given this paragraph: Homeostasis The goal of homeostasis is the maintenance of equilibrium around a specific value of some aspect of the body or its cells called a set point. While there are normal fluctuations from the set point, the body's systems will usually attempt to go back to this point. A change in the internal or external environment is called a stimulus and is detected by a receptor; the response of the system is to adjust the activities of the system so the value moves back toward the set point. For instance, if the body becomes too warm, adjustments are made to cool the animal. If glucose levels in the blood rise after a meal, adjustments are made to lower them and to get the nutrient into tissues that need it or to store it for later use. When a change occurs in an animal's environment, an adjustment must be made so that the internal environment of the body and cells remains stable. The receptor that senses the change in the environment is part of a feedback mechanism. The stimulustemperature, glucose, or calcium levelsis detected by the receptor. The receptor sends information to a control center, often the brain, which relays appropriate signals to an effector organ that is able to cause an appropriate change, either up or down, depending on the information the sensor was sending. Q: The human body wants to maintain equilibrium or balance, also known as what? A:
OPTIONS:
- perfection
- heterostasis
- stability
- homeostasis

Answer: homeostasis

Question: Answer the following question given this paragraph: Q: Particles of matter have the most definite shape in what material state? A:
OPTIONS:
- plasma
- liquid
- gas
- solid
Answer: solid

input: OPTIONS:
- Allopatric speciation
- interconnection
- spontaneous mutation
- coevolution Now, answer this question: Answer the following question given this paragraph: Two species may often interact with each other and have a close relationship. Examples include flowers and the animals that pollinate them. When one of the two species evolves new traits, the other species may evolve matching traits. This is called coevolution . You can see an example of this in Figure below . The very long beak of this hummingbird co-evolved with the tubular flowers it pollinates. Only this species of hummingbird can reach nectar deep in the flowers. Q: What is it called when two species evolve matching traits? A:
A:
output:
coevolution
