Answer the following question given this paragraph: Rivers and streams flow across continents. They cut away at rock, forming river valleys ( Figure below ). These are destructive forces. The bits and pieces of rock carried by rivers are deposited where rivers meet the oceans. These can form deltas, like the Mississippi River delta. They can also form barrier islands, like Padre Island in Texas. Rivers bring sand to the shore, which forms our beaches. These are constructive forces. Q: What type of forces are involved when deposited rock forms deltas or barrier islands? Choices: - gravity forces - accumulation forces - matter forces - constructive forces A:
constructive forces
Answer the following question given this paragraph: Many crops are grown where there isn't enough rainfall for plants to thrive. For example, crops are grown in deserts of the American Southwest. How is this possible? The answer is irrigation. Irrigation is any way of providing extra water to plants. Most of the water used in agriculture is used for irrigation. Livestock also use water, but they use much less. Q: What is the name of the process for delivering water to crops? Choices: - drainage - reclamation - bilge - irrigation A:
irrigation
Q: Answer the following question given this paragraph: The highway above switches back and forth as it climbs up the steep hillside. The much gentler slope of the road makes it easier for vehicles to reach the top of the mountain. The highway is an example of an inclined plane. Q: A highway that switches back and forth as it climbs up a steep hillside, yeilding a much gentler slope, is an example of what simple machine? Choices: - lever - pulley - wheel - inclined plane A:
A: inclined plane
Question: Answer the following question given this paragraph: The nucleus is an example of an organelle . An organelle is any structure inside a cell that is enclosed by a membrane. Eukaryotic cells may contain many different organelles. Each does a special job. For example, the mitochondrion is an organelle that provides energy to the cell. You can see a mitochondrion and several other organelles in the animal cell in Figure above . Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Q: Any structure inside a cell that is enclosed by a membrane is called? Choices: - an article - a particle - an enclave - an organelle A:
Answer: an organelle

Answer the following question given this paragraph: An example of a human polygenic trait is adult height. Several genes, each with more than one allele, contribute to this trait, so there are many possible adult heights. For example, one adult's height might be 1.655 m (5.430 feet), and another adult's height might be 1.656 m (5.433 feet) tall. Adult height ranges from less than 5 feet to more than 6 feet, but the majority of people fall near the middle of the range, as shown in Figure below . Q: Because several genes, each with more than one allele, contribute to determining height in humans, height is considered what kind of trait? Choices: - adaptive - maladaptive - epigenetic - polygenic A:
(Answer)
polygenic
