Problem: OPTIONS:
- halogens
- metalloids
- noble gases
- alkali metals
Q: Answer the following question given this paragraph: Sodium belongs to the group of elements called the alkali metals. An alkaline solution is another name for a solution that is basic. All alkali metals react readily with water to produce the metal hydroxide and hydrogen gas. The resulting solutions are basic. Q: What group of elements does sodium belong to? A:
Answer: alkali metals

Problem:OPTIONS:
- suggesting reproduction
- subject reproduction
- asexual reproduction
- sexual reproduction

Answer the following question given this paragraph: Sexual reproduction In eukaryotes, the major mechanism for shuffling genes is sexual reproduction. Because sex (usually) requires that organisms cooperate sex represents an example of social evolution. So what are the benefits of sexual reproduction? 342 Sexual reproduction involves the alternation of diploid (two copies of each chromosome) and haploid (one copy of each chromosome) cell types. In a diploid cell, the two copies of a particular gene can be different, the the organisms is said to be heterozygous for that gene. Different alleles can (but do not necessarily do) encode functionally distinct gene products and can be associated with different phenotypes (discussed in greater detail in the future two-semester version). We can then characterize different alleles with respect to one one another. Assume that allele-1 is associated with phenotype-1 342. Q: In eukaryotes, the major mechanism for shuffling genes is what? A:
****
A: sexual reproduction

Answer the following question given this paragraph: Viewed from Earth, Mars is red. This is due to large amounts of iron in the soil. The ancient Greeks and Romans named the planet Mars after the god of war because the planet's red color reminded them of blood. Mars has only a very thin atmosphere made up mostly of carbon dioxide. Q: Mars appears red because of large amounts of which element in the soil? A:
OPTIONS:
- carbon
- coal
- mercury
- iron
iron

Answer the following question given this paragraph: In food chemistry, the substances known as antioxidants are reducing agents. Ascorbic acid (vitamin C; C6H8O6) is thought to retard potentially damaging oxidation of living cells. In the process, it is oxidized to dehydroascorbic acid (C6H6O6). In the stomach, ascorbic acid reduces the nitrite ion (NO2) to nitric oxide (NO): C6H8O6 + 2H+ + 2NO2 C6H6O6 + 2H2O + 2NO If this reaction did not occur, nitrite ions from foods would oxidize the iron in hemoglobin, destroying its ability to carry oxygen. Tocopherol (vitamin E) is also an antioxidant. In the body, vitamin E is thought to act by scavenging harmful by-products of metabolism, such as the highly reactive molecular fragments called free radicals. In foods, vitamin E acts to prevent fats from being oxidized and thus becoming rancid. Vitamin C is also a good antioxidant. Finally, and of greatest importance, green plants carry out the redox reaction that makes possible almost all life on Earth. They do this through a process calledphotosynthesis, in which carbon dioxide and water are converted to glucose (C6H12O6). The synthesis of glucose requires a variety of proteins called enzymes and a green pigment called chlorophyll that converts sunlight into chemical energy (Figure 5.7 "Life on Earth"). The overall change that occurs is as follows:. Q: Photosynthesis converts carbon dioxide and water into what? A:
OPTIONS:
- insulin
- carbon
- glutamate
- glucose

Answer: glucose

input with options: Answer the following question given this paragraph: The trillions of red blood cells in blood plasma carry oxygen. Red blood cells contain hemoglobin , a protein with iron that binds with oxygen. Red blood cells are made in the marrow of long bones, rib bones, the skull, and the vertebrae. These cells survive for about 120 days, and then they are destroyed. Mature red blood cells lack a nucleus and other organelles, allowing for more hemoglobin, and therefore more oxygen to be carried by each cell. Q: What is the protein that carries iron that binds with oxygen in red blood cells? A:
OPTIONS:
- keratin
- potassium
- insulin
- hemoglobin
output:
hemoglobin
