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
Yes! Even though that area is in daylight, the Earth's axis in that hemisphere is pointing away from the Sun. It gets less direct light, and has shorter days. -
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
No. Although it is daytime in that area, the Earth's axis in that hemisphere is pointing away from the Sun. It gets less direct light, and has shorter 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.

Which of the following observations is NOT scientifically testable?
-
Butterflies have pretty wings.
Yes! Pretty is an opinion, and can vary from person to person, so it is NOT scientifically testable. -
Butterflies have six legs.
No. This could be tested by counting the legs of a variety of butterflies. -
Butterflies can sting like bees.
No. A claim does not have to be true to be testable. Examination of a variety of butterflies would show that they do not have stingers. -
Most butterflies drink nectar from flowers.
No. This could be tested by observing the feeding habits of butterflies.
Explain more about it.
If I said that butterflies did not have six legs, you could show me physical evidence by counting their legs. After counting the legs, the physical evidence would show that butterflies have six legs.
If I said that I don't think butterfly wings are pretty, you could show me wings that you think are pretty, but I might not agree with your opinion. "Pretty" is not something that we can measure. What is pretty to one person might not be pretty to another, so it is not a testable property.

When Nancy and I moved from Florida to our new home in Utah, we found that many of the flowers we grew in Florida would not grow well here. Why?
-
The soil is different.
This is part of the answer. The soil here is mostly sand, and is very alkaline. The soil in Florida had much more organic matter and was more acidic. Plants that need rich soil do not grow well here. -
The climate is different.
This is part of the answer. The climate in Utah is very different from Florida. The winters are MUCH colder (down to -20°F) and the summers are MUCH hotter (up to 125°F). The climate here is also much drier. When we lived in Jacksonville, FL, we got about 52 inches of rainfall each year. Here in Utah, we only get about 14 inches of rainfall each year. Some of the plants from Florida can grow here, but the ones that cannot stand the cold, heat, and dry conditions do not. -
The animals are different.
This is part of the answer. The wildlife here is much different from the animals in Florida. There are insects here that eat plants that were not bothered by Florida insects. There are rock squirrels, western pocket gophers, jack rabbits, mule deer, and many other animals here that love to eat many kinds of flowers. Plants that do not have a bitter taste, spines, or other ways to discourage animals do not do well here. -
All of the above.
Yes! All of the answers are correct. When you take an organism from one environment and put it into another, you may see different results. If the organism is not adapted for the new environment, it may die or not grow well. If it is very well adapted to the new environment, it may take over, crowding out some of the native organisms.
