Answer the following question given this paragraph: Electromagnetic waves vary in their wavelengths, frequencies, and energy levels. The full range of electromagnetic waves makes up the electromagnetic spectrum. Q: What do we call the full range of electromagnetic waves? Choices: - electromagnetic scale - molecular spectrum - mechanical spectrum - electromagnetic spectrum A:
electromagnetic spectrum
Answer the following question given this paragraph: The rate of radioactive decay varies from one radioisotope to another. The rate is measured by the half-life. This is the length of time it takes for half of a given amount of a radioisotope to decay. Q: How is the radioactive decay measured? Choices: - carbon dating - quarter-life - alpha emission - half-life A:
half-life

Answer the following question given this paragraph: For an exothermic chemical reaction, energy is given off as reactants are converted to products. In chemical reactions where the products have a higher energy than the reactants, the reactants must absorb energy from their environment to react. These reactions are endothermic and can be represented by an energy-level diagram like the one shown in http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gob-ch07_s04_f02. Figure 7.4 Endothermic Reactions. Q: For an exothermic chemical reaction, energy is given off as reactants are converted to what? Choices: - exports - forms - imports - products A:
**Answer**
products

Answer the following question given this paragraph: The process of assembling amino acids into a protein takes place in the ribosome. This structure consists of two subunits, each of which is composed of both proteins and ribosomal RNA (rRNA). The two subunits clamp together on the mRNA and catalyze the formation of the amide linkages in the growing protein. When protein synthesis is complete, the two subunits dissociate and release the completed protein chain. Q: Where does the process of assembling amino acids into a protein take place? Choices: - in the nucleus - in chromosomes - in the chitin - in the ribosome A:
(Answer)
in the ribosome
