Answer the following question given this paragraph: Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. For a video demonstration of the amplitude and loudness of sounds, go to this URL: http://www. youtube. com/watch?v=irqfGYD2UKw. Q: What is a measure of the size of sound waves? A:
OPTIONS:
- voltage
- wavelength
- frequency
- amplitude
amplitude

Answer the following question given this paragraph: During crossing-over, segments of DNA are exchanged between non-sister chromatids of homologous chromosomes. Notice how this can result in an allele (A) on one chromosome being moved to the other chromosome. The four chromatids compose the tetrad, with a chiasma at the point of exchange. Q: When does exchange of dna segments happen between non-sister chromatids of homologous chromosomes? A:
OPTIONS:
- during meiosis
- during mitosis
- during diversion
- during crossing-over

Answer: during crossing-over

Question: Answer the following question given this paragraph: Work is defined as the product of a force times the distance over which the force acts. The force and the distance must act along the same line; if the angle between them is not (or ) then you must use the component of force; hence the in the equation. Q: What is defined as the product of a force times the distance over which the force acts? A:
OPTIONS:
- matter
- motion
- energy
- work
Answer: work

input with options: Answer the following question given this paragraph: For a given substance, the entropy of the liquid state is greater than the entropy of the solid state. Likewise, the entropy of the gas is greater than the entropy of the liquid. Therefore, entropy increases in processes in which solid or liquid reactants form gaseous products. Entropy also increases when solid reactants form liquid products. Q: What increases in processes in which solid or liquid reactants form gaseous products and when solid reactants form liquid products? A:
OPTIONS:
- evaporation
- glucose
- respiration
- entropy
output: entropy

Q: Answer the following question given this paragraph: Gaseous nitrogen is converted into forms that can be used by plants during the process of nitrogen fixation. Q: Gaseous nitrogen is converted into forms that can be used by plants during a process called what? A:

OPTIONS:
- oxygen fixation
- dioxide fixation
- plant fixation
- nitrogen fixation

A: nitrogen fixation

Answer the following question given this paragraph: Figure 16.8 Pituitary Tumor The pituitary gland is located in the sella turcica of the sphenoid bone within the cranial floor, placing it immediately inferior to the optic chiasm. If the pituitary gland develops a tumor, it can press against the fibers crossing in the chiasm. Those fibers are conveying peripheral visual information to the opposite side of the brain, so the patient will experience "tunnel vision"meaning that only the central visual field will be perceived. Q: Which gland is located in the sella turcica of the sphenoid bone within the cranial floor? A:
OPTIONS:
- mammalian gland
- thyroid gland
- glucose gland
- pituitary gland
pituitary gland
