Why would 2 electrons repel?
It has to do with entropy. The law of entropy states that the universe tends toward having the lowest possible energy at every point. Two oppositely charged particles' magnetic fields cancel out, so, to follow this tendency, they attract each other to have more of their fields overlapping, and so, reducing the energy at each point. Two electrons are samely charged, and so, when their fields overlap the energy of each field will add together. To keep with entropy, the particles repel so that less of their fields overlap, making the energy at each point as low as possible.
How are depressions symbolized on a topographic map?
A depression is shown by contour lines with small marks pointing toward the lowest point of the depression.

How does the structure of the uterine tube move the egg toward the uterus?
The uterine tube is lined with cilia. These small hair-like projections sweep the egg toward the uterus.

What do the hairs in the nose and the mucus in the throat accomplish when someone inhales?
The air you breathe is full of tiny particles that have to be filtered out before the air can go into your lungs. The hair in your nose helps stop bits of dust and other debris from passing further into your nose. Further inside, the layer of sticky mucus catches the tiny particles that got through the hairs. The cells in your nose have microscopic hairlike projections on them called cilia. They actually beat back and forth about 16 times a second, and move the layer of mucus toward the back of your nose where it's normally swallowed. If something happens, like a particularly irritating particle gets caught in the mucus, you'll feel a tickle in your nose, triggering your sneeze reflex. It causes you to take in a big breath of air, and forcefully expel it through your mouth and nose, taking some mucus (and hopefully the irritant) with it. The mucus in your throat does the same filtering job, and irritations there cause coughing. The mucus also helps moisten the air, to make it better to breathe into your lungs.
How do neutral objects behave toward charged objects?
They do not react to charged particles.

Can you eat while standing on your head?
Yes. The throat muscles pull food toward the stomach regardless of which way you are positioned.
How do the tiny particles in the dust glitter with the aura of the moon?
Light is scattered when it hits the small dust particles. They appear to sparkle because sometimes the light is reflected toward your eyes.
