Question: Answer the following question given this paragraph: Scientists create models with computers. Computers can handle enormous amounts of data. This can more accurately represent the real situation. For example, Earth's climate depends on an enormous number of factors. Climate models can predict how climate will change as certain gases are added to the atmosphere. To test how good a model is, scientists might start a test run at a time in the past. If the model can predict the present it is probably a good model. It is more likely to be accurate when predicting the future. Q: What technology do scientists use to create models? Choices: - calculators - patterns - microscopes - computers A:
Answer: computers

Question: Answer the following question given this paragraph: Physiological Processes of Echinoderms Echinoderms have a unique system for gas exchange, nutrient circulation, and locomotion called the water vascular system. The system consists of a central ring canal and radial canals extending along each arm. Water circulates through these structures allowing for gas, nutrient, and waste exchange. A structure on top of the body, called the madreporite, regulates the amount of water in the water vascular system. "Tube feet," which protrude through openings in the endoskeleton, may be expanded or contracted using the hydrostatic pressure in the system. The system allows for slow movement, but a great deal of power, as witnessed when the tube feet latch on to opposite halves of a bivalve mollusk, like a clam, and slowly, but surely pull the shells apart, exposing the flesh within. Q: Echinoderms have a unique system for gas exchange, nutrient circulation, and locomotion called the water vascular system. the system consists of a central ring canal and radial canals extending along each arm. water circulates through these structures allowing for gas, nutrient, and this? Choices: - water evaporation - nerve exchange - cell exchange - waste exchange A:
Answer:
waste exchange
