Which mutation would be HARMFUL to the farming industry?
A mutation that causes cows to produce more milk
A mutation that causes sheep to have more wool
A mutation that causes female pigs to have less offspring
A mutation that causes an increased crop yield
A gardener crosses two plants and observes that the offspring appear different from the parents. The diagram shows the plants. Which statement supports this observation?
The plants reproduce asexually and the offspring develop new genes with age.
The plants reproduce sexually and the offspring exchange genes with each other.
The plants reproduce asexually and the offspring receive all their genes from a single parent.
The plants reproduce sexually and the offspring receive a unique combination of genes from both parents.
There are three major types of rocks: igneous, sedimentary, and metamorphic. These rock types may change from one type to another over time due to varying conditions. What important factor transforms metamorphic and igneous rocks to sedimentary rocks?
Agents of weathering
Extreme pressure
Intense heat beneath Earth's crust
Rapid cooling beneath Earth's crust
What phase is shown in the process of cell division in the image?
Anaphase
Metaphase
Prophase
Telophase
The image shows the genotypes of two parents. The (B) represents blue flowers and the (b) represents white flowers - Parent 1 - Bb x bb - Parent 2. A student lists possible offspring of a cross between the two plants. Which offspring are possible given the two parents?
1, 2, and 3
2, 3, and 4
1, 3, and 4
1, 2, and 4
A region gets its electric supply from a nearby coal power plant. Some people in the region install solar panels on their roofs to generate electricity. Factors about both electricity generated from coal and solar are listed in a table. Which is an ADVANTAGE of electricity generated from solar panels compared to coal?
Solar panels provide electricity using large panels.
Solar panels provide electricity reliably throughout the year.
Solar panels provide electricity without any cost to the come.
Solar panels provide electricity without creating ongoing pollution.
Which change is observed DUE to the convection currents in the mantle?
Tectonic plates move.
Water circulates in the ocean.
Crust becomes hotter, raising the surface temperature.
Crust becomes more dense, sinking to form trenches.
Mountains are formed as a result of tectonic activity. What justifies this inference?
When two plates move away from each other, the scraping and piling up of huge amounts of sediments and rocks form mountains
When two plates move toward each other, large amounts of molten magma flow to the surface between them to form mountains.
When two plates move toward each other, compressional forces bend the plates to form mountains
When two plates move away from each other, both plates subduct near a fault line to form mountains
The model represents a form of cell division. Based on the model, what is the result of this type of cell division.
It results in the production of daughter cells identical to the parent cell
It results in the production of daughter cells having a larger size compared to the parent cell
It results in the production of daughter cells with half the number of chromosomes compared to the parent cell.
It results in the production of daughter cells having double the number of chromosomes compared to the parent cell.
When a drum is hit with a stick, it creates a vibration, which makes a sound. The number of vibrations in a second determines what property of the sound?
Frequency
Reflection
Transmission
Wavelength
Some species of bats can gather information about their environment through the process of echolocation. In echolocation, a bat emits a sound, which reaches an object and bounces back to the bat. Which behavior of sound waves explains how bats can learn about their environment?
Absorption
Reflection
Refraction
Scattering
The diagram shows two waves, A and B. Which characterizes a difference between the two waves?
Wave A has more energy
Wave A travels with a faster speed.
Wave B has a higher frequency.
Wave B travels through more types of matter
A city is planning to build a hydroelectric power plant at site A or a wind farm at site B to meet its energy needs, as shown on the map. Which reason supports building the hydroelectric power plant instead of the wind farm?
The hydroelectric power plant uses a renewable resource
The hydroelectric power plant takes up more space than the wind farm
The hydroelectric power plant would not disrupt animal habitats.
The hydroelectric power plant would not require removing nearby natural resources
The model shows the expression of genes. Which conclusion does the model support?
Many genes can produce the same protein.
Many genes combine with DNA to form a protein
A gene contains information to produce a DNA chain.
A gene contains information to produce a specific protein.
A gorilla and a whale are both mammals, while a frog is an amphibian. The gorilla and frog use their limbs for grasping, while the whale uses them for swimming. The image shows the bones in a gorilla’s hand, whale’s flipper, and frog’s front leg with the numbers indicating the same bone type in each.
Gorillas and whales share a common ancestor with frogs because they are mammals and frogs are amphibians.
Frogs and gorillas do not share a common ancestor with whales because they use their limbs for grasping.
Different size bones in the limbs of gorillas, whales, and frogs indicate that they do not share a common ancestor
Similar bone structures in the limbs of gorillas, whales, and frogs indicate that they share a common ancestor.
