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.

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.

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 Obsidian. It is formed from molten lava that cools so quickly that it forms a natural glass instead of crystals. What kind of rock is it?.
-
Igneous
Yes! Igneous rocks formed from magma or lava. This is an igneous rock. -
Sedimentary
No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. This is not a sedimentary rock. -
Metamorphic
No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. Instead of being changed, this got hot enough to completely melt, so it is not metamorphic. -
Obsidian is not a rock.
No. Obsidian is a naturally occurring solid that forms large layers in the Earth. Obsidian is a rock.
