Answer the following question given this paragraph: Visible light is light that has wavelengths that can be detected by the human eye. The wavelength of visible light determines the color that the light appears. As you can see in the Figure below , light with the longest wavelength appears red, and light with the shortest wavelength appears violet. In between are all the other colors of light that we can see. Only seven main colors of light are actually represented in the diagram. Q: Visible light has what that can be detected by the human eye? A:
OPTIONS:
- patterns
- dimensions
- colors
- wavelengths
wavelengths

Answer the following question given this paragraph: 12.2 Bernoulli's Equation 4. You can squirt water a considerably greater distance by placing your thumb over the end of a garden hose and then releasing, than by leaving it completely uncovered. Explain how this works. Water is shot nearly vertically upward in a decorative fountain and the stream is observed to broaden as it rises. Conversely, a stream of water falling straight down from a faucet narrows. Explain why, and discuss whether surface tension enhances or reduces the effect in each case. Look back to Figure 12.4. Answer the following two questions. Why is. Q: Surface tension is a property that can be found in what state of matter? A:
OPTIONS:
- ice
- vapor
- water
- liquid

Answer: liquid

Answer: sapwood

input with options: Answer the following question given this paragraph: Finally, air passes from the bronchi into smaller passages called bronchioles. The bronchioles end in tiny air sacs called alveoli. Q: What is the name for the tiny air sacs at the end of bronchioles? A:
OPTIONS:
- gills
- vacuoles
- ganglion
- alveoli
output: alveoli

Q: Answer the following question given this paragraph: HFCs are used as a replacement for CFCs. The molecular structure of HFC134a is shown in this ball-and-stick model. Q: Hfcs are used as a replacement for what? A:

OPTIONS:
- nitrofluorocarbons
- pollutants
- gases
- cfcs

A: cfcs

Answer the following question given this paragraph: 9.3 Response to the Signal The initiation of a signaling pathway is a response to external stimuli. This response can take many different forms, including protein synthesis, a change in the cell's metabolism, cell growth, or even cell death. Many pathways influence the cell by initiating gene expression, and the methods utilized are quite numerous. Some pathways activate enzymes that interact with DNA transcription factors. Others modify proteins and induce them to change their location in the cell. Depending on the status of the organism, cells can respond by storing energy as glycogen or fat, or making it available in the form of glucose. A signal transduction pathway allows muscle cells to respond to immediate requirements for energy in the form of glucose. Cell growth is almost always stimulated by external signals called growth factors. Uncontrolled cell growth leads to cancer, and mutations in the genes encoding protein components of signaling pathways are often found in tumor cells. Programmed cell death, or apoptosis, is important for removing damaged or unnecessary cells. The use of cellular signaling to organize the dismantling of a cell ensures that harmful molecules from the cytoplasm are not released into the spaces between cells, as they are in uncontrolled death, necrosis. Apoptosis also ensures the efficient recycling of the components of the dead cell. Termination of the cellular signaling cascade is very important so that the response to a signal is appropriate in both timing and intensity. Degradation of signaling molecules and dephosphorylation of phosphorylated intermediates of the pathway by phosphatases are two ways to terminate signals within the cell. Q: Programmed cell death, which goes by what term, is important for removing damaged or unnecessary cells? A:
OPTIONS:
- mytosis
- synthesis
- mutations
- apoptosis
apoptosis
