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.

Rainbows are produced by:
-
Refraction
Partly correct. Light entering the raindrop is reflected off of the back surface. -
Reflection
Partly correct. As the light passes from air to water, and from water to air, the light is bent or refracted. Different colors are refracted different amounts, separating the colors. -
Both reflection and refraction
Correct! When you see a rainbow, the sun will always be behind you. (There are other, similar looking phenomena which you see when facing the sun, but they are not rainbows.) The sunlight enters each raindrop, is refracted (bent). Different colors are refracted different amounts. When the light hits the far side of the raindrop, part of it goes on through, and part of it is reflected back towards the sun (and towards you.) As it passes leaves the drop, the difference in density from water to air refracts (bends) the light even more, separating the colors into bands for the rainbow. -
Neither reflection no refraction
No. One or both take part in producing the rainbow.

This is Johnson Wash, that runs down the middle of the canyon where we live. It is usually dry, but when it rains up north, we get flash floods. Is this an example of erosion, weathering, both, or neither?
-
Erosion
Yes, the is partially correct! You can tell by the muddy appearance of the water that it is carrying sand, clay and dirt along with it. Erosion is when bits of rock are moved by wind, water, ice, or gravity, so this counts as erosion.. -
Weathering
Yes, the is partially correct! The term "weathering" causes confusion because it sounds like it has something to do with weather. In Earth Science, weathering means "breaking apart." Weathering breaks rocks apart into smaller bits. The fast moving water causes smaller rocks to smash into larger rocks, breaking them apart. -
Both erosion and weathering
Yes! The flash flood in this photo is causing weathering, and erosion. As the flood decreases, and the water slows down, it will drop the sand, clay, dirt, and rocks in a process called deposition. -
Neither erosion nor weathering
No. This flash flood is causing both weathering and erosion.

Eyeglasses and camera lenses change the path of light to focus an image. Which of the following is responsible for that change?
-
Refraction
Yes! Refraction bends light as it moves from one substance to another. By bending the light, we can use refraction to focus the image in a camera, or to correct the focus of the lens in our eyes. -
Reflection
No. While some light is reflected from a lens, that does not help us focus the image. -
Absorption
No. The lens is clear, telling us that very little of the light is being absorbed. Absorption does not help the lens focus. -
Diffusion
No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the image cloudy and blurry, not help focus it.
