Answer the following question given this paragraph: After each mass extinction, new species evolve to fill the habitats where old species lived. This is well documented in the fossil record. Q: The fossil record shows that this type of event is followed by the evolution of new species to fill the habitats where old species lived? A:

OPTIONS:
- minor extinction
- moderate extinction
- formation extinction
- mass extinction

Answer: mass extinction

Problem: OPTIONS:
- controlling factor
- stumbling block
- variable
- limiting factor
Q: Answer the following question given this paragraph: In the predator-prey example, one factor limits the growth of the other factor. As the prey population deceases, the predator population is begins to decrease as well. The prey population is a limiting factor. A limiting factor limits the growth or development of an organism, population, or process. Q: What is the term for something that limits the growth or development of an organism, population, or process? A:
Answer: limiting factor

Problem:OPTIONS:
- chromosomes
- chloroplasts
- nuclei
- ribosomes

Answer the following question given this paragraph: Ribosomes Ribosomes are the cellular structures responsible for protein synthesis. When viewed through an electron microscope, free ribosomes appear as either clusters or single tiny dots floating freely in the cytoplasm. Ribosomes may be attached to either the cytoplasmic side of the plasma membrane or the cytoplasmic side of the endoplasmic reticulum (Figure 3.7). Electron microscopy has shown that ribosomes consist of large and small subunits. Ribosomes are enzyme complexes that are responsible for protein synthesis. Because protein synthesis is essential for all cells, ribosomes are found in practically every cell, although they are smaller in prokaryotic cells. They are particularly abundant in immature red blood cells for the synthesis of hemoglobin, which functions in the transport of oxygen throughout the body. Q: What term is used to describe the cellular structures responsible for protein synthesis? A:
****
A: ribosomes

Problem:OPTIONS:
- the macula
- the iris
- the cornea
- the pupil

Answer the following question given this paragraph: The pupil is an opening in the front of the eye. It looks black because it doesn't reflect any light. It allows light to enter the eye. The pupil automatically gets bigger or smaller to let more or less light in as needed. Q: What is the opening in the front of the eye? A:
