Answer the following question given this paragraph: Two planets are on a collision course, heading directly towards each other at 0.250c . A spaceship sent from one planet approaches the second at 0.750c as seen by the second planet. What is the velocity of the ship relative to the first planet? 28. When a missile is shot from one spaceship towards another, it leaves the first at 0.950c and approaches the other at ships?. Q: Spinal cord injuries are notoriously difficult to treat because spinal nerves do not do what? A:
OPTIONS:
- cover
- cartilage
- moisture
- regenerate

Answer: regenerate

Question: Answer the following question given this paragraph: Your feet feel cold as you walk barefoot across the living room carpet in your cold house and then step onto the kitchen tile floor. This result is intriguing, since the carpet and tile floor are both at the same temperature. The different sensation you feel is explained by the different rates of heat transfer: the heat loss during the same time interval is greater for skin in contact with the tiles than with the carpet, so the temperature drop is greater on the tiles. Some materials conduct thermal energy faster than others. In general, good conductors of electricity (metals like copper, aluminum, gold, and silver) are also good heat conductors, whereas insulators of electricity (wood, plastic, and rubber) are poor. Q: There is a positive correlation between the ability to conduct thermal energy and what other energy, as exemplified by metals? A:
OPTIONS:
- nuclear
- gravitational
- elastic
- electricity
Answer: electricity

input with options: Answer the following question given this paragraph: Nucleic acids are biochemical molecules that contain oxygen, nitrogen, and phosphorus in addition to carbon and hydrogen. There are two main types of nucleic acids. They are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Q: Along with dna, what is the other main type of nucleic acid? A:
OPTIONS:
- nucleotides
- protein
- cytoplasm
- rna
output: rna

Q: Answer the following question given this paragraph: Eye color in humans is determined by multiple genes. Use the Eye Color Calculator (http://openstaxcollege. org/l/ eye_color_calc) to predict the eye color of children from parental eye color. In some cases, several genes can contribute to aspects of a common phenotype without their gene products ever directly interacting. In the case of organ development, for instance, genes may be expressed sequentially, with each gene adding to the complexity and specificity of the organ. Genes may function in complementary or synergistic fashions, such that two or more genes need to be expressed simultaneously to affect a phenotype. Genes may also oppose each other, with one gene modifying the expression of another. In epistasis, the interaction between genes is antagonistic, such that one gene masks or interferes with the expression of another. "Epistasis" is a word composed of Greek roots that mean "standing upon. " The alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking. Often the biochemical basis of epistasis is a gene pathway in which the expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway. An example of epistasis is pigmentation in mice. The wild-type coat color, agouti (AA), is dominant to solid-colored fur (aa). However, a separate gene (C) is necessary for pigment production. A mouse with a recessive c allele at this locus is unable to produce pigment and is albino regardless of the allele present at locus A (Figure 12.20). Therefore, the genotypes AAcc, Aacc, and aacc all produce the same albino phenotype. A cross between heterozygotes for both genes (AaCc x AaCc) would generate offspring with a phenotypic ratio of 9 agouti:3 solid color:4 albino (Figure 12.20). In this case, the C gene is epistatic to the A gene. Q: How is eye color in humans determined? A:

OPTIONS:
- random chance
- by the father
- temperature of the womb
- multiple genes

A: multiple genes

input: OPTIONS:
- brains
- tails
- eggs
- shell Now, answer this question: Answer the following question given this paragraph: The cell walls in many species of fungi contain chitin. Chitin is tough carbohydrate found in the shells of animals such as beetles and lobsters. The cell wall of a plant is made of cellulose, not chitin. Q: Chitin is a substance that is found in what part of animals like beetles and lobsters? A:
A:
output: shell
