Ques: Answer the following question given this paragraph: To return to the first image, these cars travel a distance of 500 miles over the course of the race. However, they are traveling in a circle, and the start and finish line are the same. Therefore, when the car finishes the race, it is in essentially the same position it was when it started. The car's total displacement is only a few feet. Q: In a car race on a circular track, where the start and finish line are the same, what quantity is neglible? Choices: - total acceleration - partial displacement - total distance - total displacement A:

Ques:Answer the following question given this paragraph: You consist of a great many cells, but like all other organisms, you started life as a single cell. How did you develop from a single cell into an organism with trillions of cells? The answer is cell division. After cells grow to their maximum size, they divide into two new cells. These new cells are small at first, but they grow quickly and eventually divide and produce more new cells. This process keeps repeating in a continuous cycle. Q: What process allows an individual to develop from a single cell into an organism with trillions of cells? Choices: - cell transition - Cell multiplication - cell function - cell division A:

Ans:cell division
