What happens to light waves in objects that are transparent? What are three sources of coarse particulate matter? What are some characteristics of scientific knowledge? What do we call the quantity of matter that an object contains? Who proved the presence of neutral subatomic...
What happens during absorption? Digested food molecules are absorbed in the small intestine . This means that they pass through the wall of the small intestine and into our bloodstream. Once there, the digested food molecules are carried around the body to where they are needed. What does abso...

So, in the case of our invisible black hole, we might have been able to notice it by seeing how the light coming to us from a certain section of the sky was bent relative to our expectations, knocked slightly off course by passing close to an object bending the surface of the ...
What Causes an Ectopic Pregnancy? Ectopic pregnancy happens when the fertilized egg cannot make its way down the fallopian tube to the uterus. This could be a result of scar tissue on the fallopian tube from a past surgery, which blocks the egg’s path to the uterus. Other potential factors...

How is light reflected? What determines the color of an object? A green pigment tends to most reflect which color (wavelength)? a. yellow b. red c. green d. violet What color has the highest frequency? What happens to light when it is reflected? If blue light shines on red paper, w...
If you look closely at what happens as the light wave enters the prism in the second diagram, you will notice that it bends down. This bending occurs because the light travels faster through the air than it does through the prism. When the lower portion of the wave enters the prism, it...
Light-dependent reactions When a photon of light hits the reaction center, a pigment molecule such as chlorophyll releases an electron. The released electron escapes through a series of protein complexes linked together, known as an electron transport chain. As it moves through the chain, it gener...
Condensation happens when water vapor cools down and changes back into liquid water, forming clouds. Precipitation occurs when these water droplets in clouds become heavy enough to fall back to Earth as rain, snow, sleet or hail. Water vapor also acts as a greenhouse gas, trapping heat in the...
