Q: Answer the following question given this paragraph: This equation shows that momentum is directly related to both mass and velocity. An object has greater momentum if it has greater mass, greater velocity, or both. For example, a bowling ball has greater momentum than a softball when both are moving at the same velocity because the bowling ball has greater mass. However, a softball moving at a very high velocity say, 100 miles an hour would have greater momentum than a slow-rolling bowling ball. If an object isn't moving at all, it has no momentum. That's because its velocity is zero, and zero times anything is zero. Q: Momentum is directly related to both mass and? A:

OPTIONS:
- mass
- intensity
- speed
- velocity

A: velocity

Q: Answer the following question given this paragraph: Hydrostatic Skeleton A hydrostatic skeleton is a skeleton formed by a fluid-filled compartment within the body, called the coelom. The organs of the coelom are supported by the aqueous fluid, which also resists external compression. This compartment is under hydrostatic pressure because of the fluid and supports the other organs of the organism. This type of skeletal system is found in soft-bodied animals such as sea anemones, earthworms, Cnidaria, and other invertebrates (Figure 38.2). Q: A hydrostatic skeleton is a skeleton formed by a fluid-filled compartment within the body, called what? A:

OPTIONS:
- clamon
- thallus
- endosperm
- coelom

A: coelom

Q: Answer the following question given this paragraph: During anaphase , sister chromatids separate and the centromeres divide. The sister chromatids are pulled apart by the shortening of the spindle fibers. This is like reeling in a fish by shortening the fishing line. One sister chromatid moves to one pole of the cell, and the other sister chromatid moves to the opposite pole. At the end of anaphase, each pole of the cell has a complete set of chromosomes. Q: During which phase do sister chromatids separate and the centromeres divide? A:

OPTIONS:
- cell phase
- gap cycle
- passivation
- anaphase

A: anaphase

Q: Answer the following question given this paragraph: Populations gain individuals through births and immigration. They lose individuals through deaths and emigration. These factors together determine how fast a population grows. Q: What do populations gain through births and immigration? A:

OPTIONS:
- humans
- Over Population
- Over Crowding
- individuals

A:
individuals
