Which of these sources of electricity is a renewable resource?
-
Coal
No. Coal is the fossilized remains of ancient plants, and it takes millions of years to form. -
Hydroelectric
Yes. The lake water that provides hydroelectric power is replenished every time it rains. -
Natural Gas
No. Natural Gas is a fossil fuel, and takes millions of years to form. -
Fuel Oil
No. Fuel oil comes from petroleum, which requires extremely long periods of time to form.

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.

Which of the following statements is scientifically testable?
-
These alligators are scary.
No. Being scary is not a physical property. Instead, it is an opinion. Some people might think they are scary, while other people might think they are not. -
These alligators have sharp teeth.
Yes! Careful observation would show that all three of these alligators have very sharp teeth. Anyone who put their hand into the mouth of these alligators would find out quickly that sharp teeth are a measurable, physical property that is scientifically testable.Remember that scientifically testable properties are going to be the same, no matter who tests them. For example, these alligators each have four legs, scaly skin, and lungs for breathing air. They are carnivorous, which means that they eat other animals. They are reptiles, and they lay eggs.
All of that information is based on physical evidence that can be checked and verified. You could count their legs, examine their skin, etc. These things are scientifically testable.
On the other hand, opinions are a property of the observer, not the object. I may think alligators are interesting. Someone else may thing they are scary, or ugly, or boring. You could test different people, to see if they think alligators are scary, but you can't test the alligator to see if it is scary. Opinions are not scientific evidence about the object.
-
These alligators have ugly eyes.
No. Again, this is an opinion, not a measurable, physical property. I happen to think that alligators have pretty eyes. -
These alligators are lazy.
No. Lazy is not a measurable property. I might call them lazy, but you might think that they are just waiting for something tasty to walk by. Lazy is an opinion, and is not scientifically testable.

Gall Bladder
No. The gall bladder stores the bile produced by the liver. -
Pancreas
Yes! The pancreas produces insulin. -
