Answer the following question given this paragraph: Acceleration that does not change in time is called uniform or constant acceleration. The velocity at the beginning of the time interval is called initial velocity, , and the velocity at the end of the time interval is called final velocity, . In a velocity versus time graph for uniform acceleration, the slope of the line is the acceleration. The equation that describes the curve is . Q: The velocity at the beginning of the time interval is called what? Choices: - growing velocity - internal velocity - previous velocity - initial velocity A:
initial velocity
Answer the following question given this paragraph: A: Sodium chloride is an odorless white solid that is harmless unless consumed in large quantities. In fact, it is a necessary component of the human diet. Q: What is an odorless white solid that is harmless unless consumed in large quantities? Choices: - Hydrogen - carbon chloride - oxygen chloride - sodium chloride A:
sodium chloride
Q: Answer the following question given this paragraph: Enthalpy changes are measured by using calorimetry. Q: Enthalpy changes are measured by using what? Choices: - fluorescence - inversion - infraction - calorimetry A:
A: calorimetry
Question: Answer the following question given this paragraph: Figure 28.18 Momentum is an important concept for these football players from the University of California at Berkeley and the University of California at Davis. Players with more mass often have a larger impact because their momentum is larger. For objects moving at relativistic speeds, the effect is even greater. (credit: John Martinez Pavliga). Q: Why do players with more mass often have a larger impact in football? Choices: - potential energy is lower - kinetic energy is lower - Velocity is larger - momentum is larger A:
Answer: momentum is larger

Answer the following question given this paragraph: There is a second distinction between the types of cleavage in protostomes and deuterostomes. In addition to spiral cleavage, protostomes also undergo determinate cleavage. This means that even at this early stage, the developmental fate of each embryonic cell is already determined. A cell does not have the ability to develop into any cell type. In contrast, deuterostomes undergo indeterminate cleavage, in which cells are not yet pre-determined at this early stage to develop into specific cell types. These cells are referred to as undifferentiated cells. This characteristic of deuterostomes is reflected in the existence of familiar embryonic stem cells, which have the ability to develop into any cell type until their fate is programmed at a later developmental stage. Q: In addition to spiral cleavage, protostomes also undergo which other form of cleavage? Choices: - straight - diagonal - dispersive - determinate A:
**Answer**
determinate

Answer the following question given this paragraph: You've probably been using a ruler to measure length since you were in elementary school. But you may have made most of the measurements in English units of length, such as inches and feet. In science, length is most often measured in SI units, such as millimeters and centimeters. Many rulers have both types of units, one on each edge. The ruler pictured below has only SI units. It is shown here bigger than it really is so it's easier to see the small lines, which measure millimeters. The large lines and numbers stand for centimeters. Count the number of small lines from the left end of the ruler (0.0). You should count 10 lines because there are 10 millimeters in a centimeter. Q: What is the standard measurement for mass? Choices: - volume - calories - BMI - grams A:
**Answer**
grams
