Answer the following question given this paragraph: Outside of chromosome 21 and the sex chromosomes, most embryos with extra chromosomes do not usually survive. Because chromosomes carry many, many genes, a disruption of a chromosome can cause severe problems with the development of a fetus. Individuals with one (or more) fewer chromosome usually don't survive either. Can you explain why?. Q: Embryos usually don't survive if they have extra or too few of these genetic units? A:
OPTIONS:
- phenotypes
- genes
- ribosomes
- chromosomes

Answer: chromosomes

Question: Answer the following question given this paragraph: 30.4 | Leaves By the end of this section, you will be able to: Identify the parts of a typical leaf Describe the internal structure and function of a leaf Compare and contrast simple leaves and compound leaves List and describe examples of modified leaves Leaves are the main sites for photosynthesis: the process by which plants synthesize food. Most leaves are usually green, due to the presence of chlorophyll in the leaf cells. However, some leaves may have different colors, caused by other plant pigments that mask the green chlorophyll. The thickness, shape, and size of leaves are adapted to the environment. Each variation helps a plant species maximize its chances of survival in a particular habitat. Usually, the leaves of plants growing in tropical rainforests have larger surface areas than those of plants growing in deserts or very cold conditions, which are likely to have a smaller surface area to minimize water loss. Q: The presence of what in leaf cells makes most leaves appear green? A:
OPTIONS:
- hydrogen
- sodium
- carbonate
- chlorophyll
Answer: chlorophyll

input with options: Answer the following question given this paragraph: Natural gas is delivered to homes, where it is used for cooking and heating. Natural gas is also a major energy source for powering turbines to make electricity. Natural gas releases most of its energy as heat when it burns. The power plant is able to use this heat, either in the form of hot gases or steam, to spin turbines. The spinning turbines turn generators, and the generators create electricity. Q: What type of gas is delivered to homes to use for cooking and heating? A:
OPTIONS:
- fluid gas
- compounded gas
- nuetralized gas
- natural gas
output: natural gas

Question: Answer the following question given this paragraph: A geologic map shows the different rocks that are exposed at the surface of a region. Rock units are shown in a color identified in a key. On the geologic map of the Grand Canyon, for example, different rock types are shown in different colors. Some people call the Grand Canyon "layer cake geology" because most of the rock units are in layers. Rock units show up on both sides of a stream valley. Q: What are the three main types of rocks? A:
OPTIONS:
- limestone , igneous and metamorphic
- plutonic, igneous and metmorphic
- crystalline , igneous and metamorphic
- sedimentary, igneous and metamorphic
Answer:
sedimentary, igneous and metamorphic
