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:
computers

Answer the following question given this paragraph: Cerebral palsy is a disease caused by injury to the developing brain. The injury occurs before, during, or shortly after birth. Cerebral palsy is more common in babies that have a low weight at birth. But the cause of the brain injury is not often known. The disease usually affects the parts of the brain that control body movements. Symptoms range from weak muscles in mild cases to trouble walking and talking in more severe cases. There is no known cure for cerebral palsy. Q: Cerebral palsy is a disease caused by injury to what organ as it is developing? Choices: - heart - skin - liver - brain A:
(A).
brain

Ans:solutes
Ques: Answer the following question given this paragraph: Binary fission can be described as a series of steps, although it is actually a continuous process. The steps are described below and also illustrated in Figure below . They include DNA replication, chromosome segregation, and finally the separation into two daughter cells. Q: Dna replication, chromosome segregation, and the separation into two daughter cells are steps in what process? Choices: - reproductive fission - nuclear fission - multiple fission - binary fission A:
Ans:
binary fission
