Why does this grasshopper have such small wings?
-
Because this species does not fly.
No. This species of grasshopper does fly. -
Because it has a mutation.
No. This is a normal grasshopper, not a mutant. -
Because it is a cricket, not a grasshopper.
No. This is a grasshopper. -
Because it is not an adult.
Yes! Grasshoppers have incomplete metamorphosis. The immature grasshoppers look similar to adults, but have some differences. The immature stages of the grasshopper has small wings, but the adult stage has large, functional wings.

Pine trees do not have flowers. What structure do they have that servers the same purpose?
-
Needles
No. Pine needles are a kind of leaf. They are not used for reproduction. -
Cones
Yes! Pine cones produce pollen and seeds, just as flowers do in flowering plants. -
Fruit
No. Fruit are used for dispersing seeds, not for pollination. -
Buds
No. Pine tree buds produce needles. They are not involved in reproduction.

These layers have not been overturned or folded. Based on that, which layer is the oldest?
-
A
No. A is on top, which means the other layers had to be there before it could be deposited. A is younger than B and C. -
B
No. By the law of Superposition, layer C had to be in place before B could form on top of it. Layer B is older than A, but younger than C. -
C
Yes! As the bottom layer, the Law of Superposition tells us that it is older than layers A and B. This layer had to be in place before A and B could form on top of it.. -
D
No. Layer D is actually a pile of rock fragments, mostly from layer A. These fragments are the result of weathering and erosion of layers A, B, and C. D is the youngest deposit at this location.

None of these layers have been turned upside down. Based on the Law of Superposition, which layer is the oldest?
-
A
No. Layer A is on top of layer B, so it is younger than layer B. That means that it is not the oldest. -
B
No. If you look at layer B, it is on top of layer C, which means that it is younger than layer C. B is not the oldest. -
C
No. Look closely at the top part of layer C. The top part of layer C is on top of part of layer D. That tells us that layer C is younger than layer D. -
D
Yes! This one is a bit tricky, because of the way the rocks were formed. Layer D formed first, as a flat, horizontal layer. Erosion weathered the left part of D away, forming a sloping hillside. Image the photo with layers A, B, and C erased, and it looks like a sloping hillside.Next, a nearby volcano erupted, spewing out lots of volcanic ash. The ash covered the hillside, forming layer C.
Next, lava from the volcano flowed down over the ash, forming layer B.
Later, the volcano erupted again, depositing another layer of volcanic ash to form layer A. After that, layer A was covered by another layer of lava, and then another layer of volcanic ash.
So A is the youngest, followed by B, then C, and D is the oldest.

These are the four stages of a mealworm's life cycle. What kind of life cycle is it?
-
Incomplete metamorphosis
No. For an incomplete metamorphosis, there are only three stages: egg, larva, and adult. The young also look very similar to the adults. The mealworm larva looks very different from the beetle. -
Complete metamorphosis.
Yes! For a complete metamorphosis, the animal goes through four stages: egg, larva, pupa, and adult. -
Full metamorphosis.
No. There is no life cycle called full metamorphosis. -
Partial metamorphosis.
No. There is no life cycle called partial metamorphosis.
