Answer the following question given this paragraph: Alpha, beta, and gamma emissions have different abilities to penetrate matter. The relatively large alpha particle is easily stopped by matter (although it may impart a significant amount of energy to the matter it contacts). Beta particles penetrate slightly into matter, perhaps a few centimeters at most. Gamma rays can penetrate deeply into matter and can impart a large amount of energy into the surrounding. Q: Alpha, beta, and gamma emissions are associated with what kind of energy? Choices: - kinetic - electrical - potential - radiation A:
(Answer)
radiation
Ques: Answer the following question given this paragraph: Some materials have negative heats of solution; the dissolution of one of these solutes in water is an exothermic process. Heat is released, causing a net increase in the temperature of the solution. Conversely, other substances have positive heats of solution. For example, the dissolution of potassium nitrate in water is an endothermic process. The resulting absorption of energy causes the solution to become colder. Calculations involving heats of solutions follow the same basic approach that we have used with other enthalpy problems. Q: Some materials have negative heats of solution; the dissolution of one of these solutes in water is called? Choices: - endothermic process - acetylene process - ionized process - exothermic process A:
Ans: exothermic process

Answer the following question given this paragraph: Q: Distinguishing between homology and analogy is critical in reconstructing what? Choices: - residues - phylums - proteases - phylogenies A:
(A).
phylogenies
Ques: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:

Ans:dominant allele
Ques:Answer the following question given this paragraph: The Moon has a crust, mantle, and core. Q: The moon has a crust, mantle, and a? Choices: - ice cap - magnetic field - mountain range - core A:

Ans:
core
