Answer the following question given this paragraph: In sexually reproducing species, chromosomes are present in cells in pairs. Chromosomes in the same pair are called homologous chromosomes. They have the same genes at the same loci. These may be the same or different alleles. During meiosis, when gametes are produced, homologous chromosomes separate. They go to different gametes. Thus, the alleles for each gene also go to different gametes. Q: What are chromosomes in the same pair called? A:

OPTIONS:
- homogeneous chromosomes
- regulated chromosomes
- reversible chromosomes
- homologous chromosomes

Answer: homologous chromosomes

Problem: OPTIONS:
- length
- weight
- height
- material
Q: Answer the following question given this paragraph: Volume is another way of measuring material. Gases cannot be easily weighed, but their volume can be determined quickly and accurately. Liquid chemicals as well as foods and beverages are also sold by volume. Gasoline for our cars and trucks is sold by the gallon. At the grocery store, we can buy a gallon of milk or a two-liter bottle of soda pop. Q: Volume is another way of measuring what? A:
Answer: material

Answer the following question given this paragraph: When skater 2 runs into skater 1, he's going faster than skater 1 so he has more momentum. Momentum is a property of a moving object that makes it hard to stop. It's a product of the object's mass and velocity. At the moment of the collision, skater 2 transfers some of his momentum to skater 1, who shoots forward when skater 2 runs into him. Whenever an action and reaction such as this occur, momentum is transferred from one object to the other. However, the combined momentum of the objects remains the same. In other words, momentum is conserved. This is the law of conservation of momentum . Q: What property of an object is obtained by multiplying its mass and its velocity? A:
OPTIONS:
- fluid
- component
- movement
- momentum
momentum

Answer the following question given this paragraph: Some of the most interesting kinds of evidence for evolution are body parts that have lost their use through evolution ( Figure below ). For example, most birds need their wings to fly. But the wings of an ostrich have lost their original use. Structures that have lost their use through evolution are called vestigial structures . They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose. Q: Structures that have lost their use through evolution are called _______ A:
OPTIONS:
- primordial structures
- residual structures
- symbiotic structures
- vestigial structures

Answer:
vestigial structures
