Question: Answer the following question given this paragraph: AcidBase Titrations Because most common acids and bases are not intensely colored, a small amount of an acid base indicator is usually added to detect the equivalence point in an acidbase titration. The point in the titration at which an indicator changes color is called theendpoint. The procedure is illustrated in Example 21. Q: The point in the titration at which an indicator changes color is called what? A:
OPTIONS:
- zeta point
- tipping point
- chromatic point
- end point
Answer: end point

input with options: Answer the following question given this paragraph: The most widely accepted theory explaining how muscle fibers contract is called the sliding filament theory . According to this theory, myosin filaments use energy from ATP to "walk" along the actin filaments with their cross bridges. This pulls the actin filaments closer together. The movement of the actin filaments also pulls the Z lines closer together, thus shortening the sarcomere. Q: What is the most widely accepted theory explaining how muscle fibers contract? A:
OPTIONS:
- sliding pigment theoery
- sliding tritium theory
- sliding carbon theory
- sliding filament theory
output: sliding filament theory

Q: Answer the following question given this paragraph: Aging occurs as cells lose their ability to divide. Q: Aging occurs as cells lose their ability to do what? A:

OPTIONS:
- fold
- split
- duplicate
- divide

A: divide

input: OPTIONS:
- subsets
- Chromosomes
- quasars
- autosomes Now, answer this question: Answer the following question given this paragraph: In a given species, chromosomes can be identified by their number, size, centromere position, and banding pattern. In a human karyotype, autosomes or "body chromosomes" (all of the nonsex chromosomes) are generally organized in approximate order of size from largest (chromosome 1) to smallest (chromosome 22). The X and Y chromosomes are not autosomes. However, chromosome 21 is actually shorter than chromosome 22. This was discovered after the naming of Down syndrome as trisomy 21, reflecting how this disease results from possessing one extra chromosome 21 (three total). Not wanting to change the name of this important disease, chromosome 21 retained its numbering, despite describing the shortest set of chromosomes. The chromosome "arms" projecting from either end of the centromere may be designated as short or long, depending on their relative lengths. The short arm is abbreviated p (for "petite"), whereas the long arm is abbreviated q (because it follows "p" alphabetically). Each arm is further subdivided and denoted by a number. Using this naming system, locations on chromosomes can be described consistently in the scientific literature. Q: What is another term for body chromosomes? A:
A:
output: autosomes

Answer the following question given this paragraph: Cutting down on the use of chemical fertilizers is one way to prevent dead zones in bodies of water. Preserving wetlands is also important. Wetlands are habitats such as swamps, marshes, and bogs where the ground is soggy or covered with water much of the year. Wetlands slow down and filter runoff before it reaches bodies of water. Wetlands also provide breeding grounds for many different species of organisms. Q: Cutting down on the use of chemical fertilizers and preserving wetlands are ways to prevent what "unlivable" regions in bodies of water? A:

OPTIONS:
- inhabitable zones
- hostile zones
- fresh zones
- dead zones

Answer: dead zones

Q: Answer the following question given this paragraph: Electron transport is the final stage of aerobic respiration. In this stage, energy from NADH and FADH 2 , which result from the Krebs cycle, is transferred to ATP. Can you predict how this happens? ( Hint: How does electron transport occur in photosynthesis?). Q: What is the final stage of aerobic respiration, when energy from the krebs cycle is transferred to atp? A:

OPTIONS:
- glycolysis
- acetyl-CoA
- cytoplasm transport
- electron transport

A:
electron transport
