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.

What do you have to do to replicate an experiment?
-
You do the same experiment several times.
No. Doing the same experiment several times is repetition, not replication. -
You do the same experiment that someone else did.
Yes. By replicating an experiment exactly, you should get the same results as the original experiment. -
You do an improved version of someone's experiment.
For replication, you do the experiment exactly as the original scientist did, without making any changes. -
You look for errors in someone's experiment.
The purpose of replication is to verify, not to look for errors.

This is called Marble. It was once limestone, but heat and pressure changed it, recrystallizing the calcite and distorting the layers. What kind of rock is it?.
-
Igneous
No. Igneous rocks formed from magma or lava. This is not an igneous rock. -
Sedimentary
No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. When it was limestone it was a sedimentary rock, but not now. -
Metamorphic
Yes!. This marble been changed by heat and pressure from a different kind of rock. It is metamorphic. -
Marble is not a rock.
No. Marble is a naturally occurring solid that forms large layers in the Earth. Marble is a rock.

The nucleus of the cell contains most of the cell's DNA. Which other structure in the cell contains DNA?
-
Mitochondria
Yes! Your mitochondria have their own DNA. Unlike the DNA in the cell's nucleus, which is a mix of genes from your father and mother, all of your mitochondrial DNA comes from your mother. -
Endoplasmic Reticulum
No. The endoplasmic reticulum is involved in the folding and movement of proteins in the cell. -
Chloroplast
No. Chloroplasts contain chlorophyll, which is used in photosynthesis. -
Ribosome
No. Ribosomes are parts of the cell that assemble proteins.

Which of these is NOT an arthropod?




-
A: Horsefly
No. Arthropods have an exoskeleton, a segmented body, and jointed legs. Like other insects, horseflies are arthropods. -
B: Fiddler Crab
No. The Fiddler Crab has an exoskeleton, a segmented body, and jointed legs. That tells us that they are arthropods. -
C: Snail
Yes! The body of a snail is not segmented, an does not have any legs, much less jointed legs. It is NOT an arthropod. Instead, it belongs to a group of mollusks called gastropods. -
D: Praying Mantis
No. The Praying Mantis has an exoskeleton, a segmented body, and jointed legs. Like other insects, a Praying Mantis is an arthropod.
