The Common Raven is often a scavenger, but its beak is not strong enough to tear through the thick hide of a winter-killed deer.
It will sit near the carcass and call loudly, attracting other ravens. As the mob gathers, they start making distress calls. That usually attracts a large predator, such as a wolf or coyote. They wait until the predator tears into the carcass.
At that point, 3 or 4 of them will start harassing the predator, keeping its attention, while the other ravens steal parts of the carcass. They then share what they get with the ravens that kept the predator busy.
This is an example of what kind of relationship?
-
mutualism
Yes! In mutualism, both organisms benefit. The ravens help the predator find the carcass, and the predator tears it open so that the ravens can eat some too. Both get a benefit from the relationship. -
commensalism
No. In commensalism, one organism benefits, and the other is not affected. In this case, the ravens and the predator both benefit. -
parasitism
No. For parasitism, one organism benefits, and the other is harmed. Neither the raven nor the predator is harmed by this relationship. -
predation
No. In predation, one organism eats another. Neither the raven nor the predator gets eaten in this relationship.

What season is the area that the arrow points to having?
-
Winter
No. In winter, the Earth's axis for that hemisphere would be pointed away from the Sun. -
Spring
No. For spring, the Earth's axis for that hemisphere would be in between pointing towards the Sun and away from the Sun. -
Summer
Yes! Even though that area is experiencing night, the Southern hemisphere is pointed towards the Sun. That means that it gets more direct sunlight and longer days. -
Autumn
No. For autumn, the Earth's axis for that hemisphere would be in between pointing towards the Sun and away from the Sun.

Incandescent light bulbs use electrical energy to produce light energy, but it is not a direct transformation. Instead, the electrical energy is changed to a different form of energy, and then to light.
Electricity → ? → Light
What form of energy does the "?" represent?
-
Sound
No. Electrical energy can be transformed into sound energy, but that would not cause the bulb to light. -
Thermal
Yes. As electrical energy flows through the filament, resistance changes the electrical energy into thermal energy. When the filament gets hot enough, some of the thermal energy is converted into light. -
Radiation
No. The electrical energy is not transformed into radiation. -
Friction
No. The electrical energy is not transformed into friction.

This is called Fluorite. It is used in making many important chemicals. What kind of rock is it?.
-
Igneous
No. Igneous rocks formed from magma or lava. Fluorite is sometimes found as a mineral in igneous rock, but it is not an igneous rock. -
Sedimentary
No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. Fluorite is not a sedimentary rock. -
Metamorphic
No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. Fluorite is not metamorphic. -
Fluorite is not a rock.
Yes! Fluorite is a mineral, not a rock. It is not found in large layers in the Earth.

I put a paper plate on top of a glass of water. I turned it over, and the water stayed in the glass.
The weight of the water is pushing down on the paper plate, but the plate stays in the glass because the pull of gravity is being balanced by another force. What is that force?
-
Attraction
No. The slight attraction between the water and the glass is not enough to balance the pull of gravity. -
Air pressure
Yes! Because the plate is keeping outside air from entering the glass, outside air pressure is keeping the plate in place. As long as the outside air pressure is enough to balance the weight of the water and the plate, it will stay in place. If you made a small hole in the glass to let outside air get in, that would unbalance things, and the water would fall out. -
Surface tension
No. The water tension at the surface of the water would not balance the force of gravity. -
The weight of the paper card
No. Gravity is pulling down on the paper plate and the water. The weight of the paper does not help balance the force of gravity.
