Answer the following question given this paragraph: Muscles can only contract. They cannot actively extend, though they can move or relax back into the non-contracted neutral position. Therefore, to move bones in opposite directions, pairs of muscles must work in opposition. Each muscle in the pair works against the other to move bones at the joints of the body. The muscle that contracts to cause a joint to bend is called the flexor . The muscle that contracts to cause the joint to straighten is called the extensor . When one muscle is contracted, the other muscle from the pair is always elongated. Q: What is the name of the muscle that contracts to cause the joint to straighten? A:
OPTIONS:
- flexor
- abductor
- opposing
- extensor

Answer: extensor

Question: Answer the following question given this paragraph: Cancer treatments vary depending on the disease's type and stage. Traditional approaches, including surgery, radiation, chemotherapy, and hormonal therapy, aim to remove or kill rapidly dividing cancer cells, but these strategies have their limitations. Depending on a tumor's location, for example, cancer surgeons may be unable to remove it. Radiation and chemotherapy are difficult, and it is often impossible to target only the cancer cells. The treatments inevitably destroy healthy tissue as well. To address this, researchers are working on pharmaceuticals that can target specific proteins implicated in cancer-associated molecular pathways. Q: Depending on a tumor's location, for example, cancer surgeons may be unable to remove it. radiation and chemotherapy are difficult, and it is often impossible to target only the cancer cells. the treatments inevitably destroy this? A:
OPTIONS:
- carcinogens
- fertility
- host cells
- healthy cells
Answer: healthy cells

input with options: Answer the following question given this paragraph: Aerobic respiration begins with the entry of the product of glycolysis, pyruvate, into the mitochondria. For each initial glucose molecules, two pyruvate molecules will enter the mitochondria. Pyruvate, however, is not the molecule that enters the Krebs cycle. Prior to entry into this cycle, pyruvate must be converted into a 2-carbon acetyl-CoenzymeA (acetyl-CoA) unit. The conversion of pyruvate into acetyl-CoA is referred to as the pyruvate dehydrogenase reaction. It is catalyzed by the pyruvate dehydrogenase complex. This process produces one NADH electron carrier while releasing a CO 2 molecule. This step is also known as the link reaction or transition step, as it links glycolysis and the Krebs cycle. Of course, as two pyruvates result from glycolysis, two acetyl-CoAs are produced as are 2 NADH molecules. Q: For each initial glucose molecules, two pyruvate molecules will enter where? A:
OPTIONS:
- the plasma
- the nucleus
- Golgi apparatus
- the mitochondria
output: the mitochondria

Q: Answer the following question given this paragraph: Respiration is the process in which gases are exchanged between the body and the outside air. The lungs and other organs of the respiratory system bring oxygen into the body and release carbon dioxide into the atmosphere. Q: What is the process in which gases are exchanged between the body and the outside air? A:

OPTIONS:
- ingestion
- metabolism
- precipitation
- respiration

A: respiration

input: OPTIONS:
- tannin
- melatonin
- cytoplasm
- melanin Now, answer this question: Answer the following question given this paragraph: Human skin color is primarily due to the presence of the pigment melanin in the skin. Melanin is not a protein, but it is the product of a biosynthetic pathway. Skin color is a polygenic trait and obviously demonstrates quantitative characteristics. A number of genes factor into determining a person's natural skin color, so modifying only one of those genes changes the color only slightly. It is currently thought that at least three separately inherited genes contribute to skin pigmentation. Let's call these three genes A, B, and C. A, B, and C are incompletely dominant to a, b, and c, with A, B, and C each contributing a "unit of darkness" to the phenotype. Therefore an AABBCC individual is very dark, darker than an AaBbCc individual, and much darker than a aabbcc individual. A person may have as many as 6 "dark units" to as few as no "dark units," and any combination in between. This will result in a phenotypic spectrum of color gradation. When graphed, a phenotypic spectrum usually results in a bell-shaped curve, with extreme phenotypes on both ends and more common phenotypes in the center of the curve. Q: Human skin color is primarily due to the presence of what pigment in the skin? A:
A:
output: melanin

Question: Answer the following question given this paragraph: All living things are made of matter . In fact, matter is the "stuff" of which all organisms are made. Anything that occupies space and has mass is known as matter. Matter, in turn, consists of chemical substances. It is the carbons, hydrogens, oxygens and other elements that combine to form molecules, compounds, organelles, cells and eventually tissues, organs and organisms. In addition to being made of matter, all living organisms also need energy to survive. Q: Anything that occupies space and has mass is known as what? A:
OPTIONS:
- opaque
- solid
- dense
- matter
Answer:
matter
