Naomi has a pet dog. Which of the following characteristics did the dog most likely inherit from its parents?
-
Its weight
-
Its favorite food
-
The color of its fur
-
The place where it lives
Correct Answer
A. The color of its furExplanation
The dog most likely inherited the color of its fur from its parents. This is because fur color is a genetic trait that is passed down from one generation to the next. The genes responsible for fur color are present in the dog's parents and are passed on to their offspring. Therefore, it is highly likely that the dog's fur color is determined by the genes inherited from its parents.Rate this question:

A tuna is an ocean fish that is well adapted to catiching small, fast-moving prey. Which of the following adaptations most helps a tuna swim fast to catch its prey?
-
Large fins
-
Sharp teeth
-
Small gills
-
Tough scales
Correct Answer
A. Large finsExplanation
Large fins are an adaptation that helps a tuna swim fast to catch its prey. Fins provide stability and maneuverability in water, allowing the tuna to change direction quickly and swim at high speeds. The large size of the fins increases surface area, which generates more thrust and propels the tuna forward. This adaptation enables the tuna to effectively chase and capture its fast-moving prey in the ocean.Rate this question:

Approximately how long does Earth take to complete its orbit around the sun?
-
One day
-
One month
-
One year
-
One century
Correct Answer
A. One yearExplanation
Earth takes approximately one year to complete its orbit around the sun. This is known as a revolution or a full orbit. It is the time it takes for Earth to travel around the sun and return to its starting position. This duration is significant as it determines the length of our calendar year and the change of seasons.Rate this question:

Which of the following statements best explains why magnets usually stick to a refrigerator door?
-
The refrigerator door is smooth.
-
The refrigerator door contains iron.
-
The refrigerator door is a good conductor.
-
The refrigerator door has electric wires in it.
Correct Answer
A. The refrigerator door contains iron.Explanation
Magnets usually stick to a refrigerator door because the door contains iron. Iron is a magnetic material, meaning it can be attracted to magnets. Therefore, when a magnet is brought close to the refrigerator door, the iron in the door is attracted to the magnet, causing the magnet to stick to the door. This is why magnets are commonly used to hold things on refrigerator doors.Rate this question:

A squid is an animal that lives in the ocean. It pumps a stream of water out of its body, causing it to move rapidly. Which of the following mechanical systems moves in a way most similar to the squid?
-
A bus
-
A helicopter
-
A rocket
-
A train
Correct Answer
A. A rocketExplanation
A rocket moves in a way most similar to a squid. Both a rocket and a squid propel themselves by expelling a fluid (water in the case of a squid, and exhaust gases in the case of a rocket) out of their bodies. This expulsion of fluid creates a reaction force that propels them forward. Similarly, both a rocket and a squid move rapidly due to the force generated by the expulsion of fluid.Rate this question:

Sandra puts some pill bugs into an open box. She covers half the box with a piece of cardboard. She then places the box outside on a summer day, and all the pill bugs move under the cardboard. The pill bugs are most likely responding to which of the following?
-
Air pressure
-
Bright light
-
Wind
-
Fog
Correct Answer
A. Bright lightExplanation
The pill bugs are most likely responding to bright light. Pill bugs are known to be negatively phototactic, meaning they prefer dark or shaded areas. By covering half of the box with a piece of cardboard, Sandra creates a dark area under the cardboard, which attracts the pill bugs to move towards it. This behavior is a natural response to avoid bright light and seek a more suitable environment for the pill bugs.Rate this question:

A student hears the sound of a bell. Which of the following carries the sound of the bell to the student?
-
Electrical currents
-
Magnetic signals
-
Radio waves
-
Vibrating air
Correct Answer
A. Vibrating airExplanation
When a bell is rung, it creates vibrations in the air. These vibrations travel through the air as sound waves and reach the student's ears, allowing them to hear the sound of the bell. Therefore, vibrating air carries the sound of the bell to the student.Rate this question:

A student sorted mineral samples into two groups: dull and shiny. Which of the following properties did the student use to sort the mineral samples into groups?
-
Cleavage
-
Color
-
Luster
-
Streak
Correct Answer
A. LusterExplanation
The student used luster to sort the mineral samples into groups. Luster refers to the appearance or quality of light reflected from the surface of a mineral. Minerals can have different luster properties such as metallic, glassy, dull, or shiny. By observing the luster of the mineral samples, the student was able to categorize them into two groups: dull and shiny.Rate this question:

Which of the following changes is caused by removing heat?
-
A solid changes to a gas.
-
A liquid changes to a gas.
-
A solid changes to a liquid.
-
A liquid changes to a solid
Correct Answer
A. A liquid changes to a solidExplanation
When heat is removed from a substance, it causes the molecules to lose energy and slow down. This decrease in energy and motion causes the substance to undergo a phase change from a liquid to a solid. The particles in a liquid have more freedom to move and are less tightly packed compared to a solid. So, when heat is removed, the particles lose energy and become more tightly packed, forming a solid.Rate this question:
