Answer the following question given this paragraph: Eris is the largest known dwarf planet in the solar system. It is 27 percent larger than Pluto ( Figure above ). Like Pluto and Makemake, Eris is in the Kuiper belt. But Eris is about three times farther from the Sun than Pluto. Because of its distance, Eris was not discovered until 2005. Early on, it was thought that Eris might be the tenth planet. Its discovery helped astronomers realize that they needed a new definition of "planet. " Eris has a small moon that orbits Eris once about every 16 days. Q: What large dwarf planet in our solar system was only discovered in 2005? Choices: - artemis - Cerus - zeus - eris A:
eris

Question: Answer the following question given this paragraph: The expression of an organism's genotype is called its phenotype . The phenotype refers to the organism's traits, such as purple or white flowers. Different genotypes may produce the same phenotype. This will be the case if one allele is dominant to the other. Both BB and Bb genotypes in Table 6.1 have purple flowers. That's because the B allele is dominant to the b allele, which is recessive. The terms dominant and recessive are the terms Mendel used to describe his "factors. " Today we use them to describe alleles. In a Bb heterozygote, only the dominant B allele is expressed. The recessive b allele is expressed only in the bb genotype. Q: In a heterozygote with one dominant and one recessive allele, which is expressed? Choices: - dominant atoms - submissive allele - dominant elements - dominant allele A:
Answer: dominant allele

Answer the following question given this paragraph: Not only salt, but many other solutes can dissolve in water. In fact, so many solutes can dissolve in water that water has been called the universal solvent. Even rocks can dissolve in water, which explains the cave that opened this article. A solute that can dissolve in a given solvent, such as water, is said to be soluble in that solvent. Conversely, a solute that cannot dissolve in a given solvent is said to be insoluble in that solvent. Q: What liquid is referred to as the "universal solvent"? Choices: - bromine - gasoline - blood - water A:
