EOG Review - 8.E.1.3, 8.P.1.3, 8.L.2.1

How did Marquez and Jasmine use genetic engineering in their biotechnology project?

• They used genetic engineering to produce organic food for their school cafeteria.

• They used genetic engineering to create a new species of drought-resistant plants.

• They used genetic engineering to manipulate the genetic material of crops to create genetically modified organisms (GMOs) with desired traits such as increased yield and pest resistance.

• They used genetic engineering to control the weather for their school's outdoor events.

Answer explanation

Genetic engineering is used to manipulate the genetic material of organisms to create genetically modified organisms (GMOs) with desired traits.

During a hot summer day, Jasmine decides to cut a popsicle into smaller pieces to share with Kevins, De'Andria, Kayla, and Lacelle. Which type of change is this an example of?

• Burning wood

• Cutting a popsicle into smaller pieces

• Mixing salt in water

• Melting ice cream

Answer explanation

The correct example of a physical change is cutting a piece of paper into smaller pieces, as it does not change the chemical composition of the paper.

Explain a chemical change that occurs in everyday life.

• Glass breaking

• Paper tearing

• Iron rusting

• Water boiling

Answer explanation

Iron rusting is a chemical change where iron reacts with oxygen in the presence of water or moisture, forming iron oxide (rust) on the surface.

During a field trip to a local river, Marquez and Kayla observed various fish species thriving in the water. They discussed how the river, as part of the hydrosphere, impacts the surrounding ecosystems. What did they likely conclude?

• The hydrosphere impacts ecosystems by providing habitats, regulating temperatures, influencing weather patterns, and facilitating nutrient cycling.

• The hydrosphere impacts ecosystems by causing droughts and floods.

• The hydrosphere impacts ecosystems by reducing soil erosion.

• The hydrosphere impacts ecosystems by increasing biodiversity.

Answer explanation

The hydrosphere impacts ecosystems by providing habitats, regulating temperatures, influencing weather patterns, and facilitating nutrient cycling.

During a science project, Jasmine and Brandon observed a local pond over a month and noted changes in water quality due to nearby construction. How does this scenario reflect the impact of water pollution on the hydrosphere?

• Water pollution benefits aquatic life

• Water pollution from construction runoff contaminates the pond, leading to a decrease in water quality, harm to aquatic life, disruption of ecosystems, and potential threats to human health.

• Water pollution has no impact on the hydrosphere

• Water pollution leads to increased water quality

Answer explanation

Water pollution contaminates water bodies, leading to a decrease in water quality, harm to aquatic life, disruption of ecosystems, and potential threats to human health.

During a science project, De'Andria and Kayla are exploring renewable energy sources that are derived from the hydrosphere. Which option are they likely to study?

• Wave energy

• Ocean thermal energy conversion

• Tidal power

• Hydropower

Answer explanation

Hydropower is a renewable energy source derived from the hydrosphere, generated by harnessing the energy of moving water in rivers, streams, and oceans.

Jasmine and Andre were discussing the differences between melting ice into water and burning paper. Jasmine argued that melting ice is a physical change because it alters the form of ice without changing its chemical composition, while burning paper is a chemical change because it results in the formation of new substances. Who is correct?

• Andre is correct; melting ice results in the formation of new substances, while burning paper alters the form or appearance of a substance without changing its chemical composition.

• Jasmine is correct; melting ice involves a change in color, while burning paper does not affect color.

• Andre is correct; melting ice is reversible, while burning paper is irreversible.

• Jasmine is correct; melting ice alters the form or appearance of a substance without changing its chemical composition, while burning paper results in the formation of new substances with different chemical compositions.

Answer explanation

Physical changes alter the form or appearance of a substance without changing its chemical composition, while chemical changes result in the formation of new substances with different chemical compositions.

During a camping trip, Jasmine and Kayla are discussing if the river water nearby is safe for drinking. What are they assessing about the water?

• Suitability for drinking without causing harm to health

• Ability to generate electricity

• Color of the water

• Resistance to extreme temperatures

Answer explanation

Potability of water refers to the suitability for drinking without causing harm to health, making it safe for consumption.

Jasmine is working on a science project about agriculture. She is focusing on how to improve crop yield in a sustainable way. What is a common application of genetic engineering in agriculture that she might explore?

• Using pesticides to enhance crop growth

• Implementing organic farming practices

• Genetically modified animals for agriculture

• Genetically modified crops with desirable traits

Answer explanation

Genetically modified crops with desirable traits are a common application of genetic engineering in agriculture, allowing for improved yield, resistance to pests, and other beneficial characteristics.

Marquez observes a cup of ice left on the table at room temperature and notices a change. Describe the physical change that occurs to the ice in the cup.

• Ice changes from a solid to a liquid state.

• Ice changes from a liquid to a gas state.

• Ice changes its chemical composition when it melts.

• Ice changes color when it melts.

Answer explanation

Ice changes from a solid to a liquid state, indicating a physical change.
