As shown in Figure 1, an amino acid must have which of the following properties in order to be incorporated into a polypeptide?

Which type of radioactive decay produces particles with a positive charge and very small mass? Which type of radioactive decay produces radiation with zero mass? Which type of radioactive decay produces radiation that requires lead shielding?

Which would result in radioactive decay? Check all that apply.a neutron-to-proton ratio of 1:1 in a small nucleusa neutron-to-proton ratio of 1:2 in a large nucleusa nucleus that contains 90 protons and 100 neutronsa nucleus that contains 8 protons and 8 neutronsany isotope of the element uranium, which has atomic number 92any isotope of the element potassium, which has atomic number 19

Which statement describes the differences between nuclear reactions and chemical reactions?Nuclear reactions involve changes to electrons, while chemical reactions involve changes to protons and neutrons.Only chemical reactions can be exothermic.Chemical reactions can result in new compounds, while nuclear reactions can result in new elements.

Which statement best describes the two reactions? A Cl2 + H2 -> 2HCl B ^2/1 H + ^3/1 H -> ^4/2 He + ^1/0 nReaction A involves a greater change, and reaction B involves a change in element identity.Reaction B involves a greater change and a change in element identity.Reaction A involves a greater change and a change in element identity.Reaction B involves a greater change, and reaction A involves a change in element identity.

isotopes behave similarly in__________involve only a rearrangement of electrons, and do not involve changes in protons or neutrons.In_______a large amount of energy is released or absorbed.New elements can be formed as a result of______Exothermic and endothermic reactions can occur during

Which type of radioactive decay produces radiation that can be stopped by a sheet of paper? Which type of radioactive decay produces particles with the most mass?

Which of these statements are the same for both nuclear reactions and chemical reactions? Check all that apply.Both can be represented by balanced equations.Both involve changes to electron arrangements in atoms.Both involve a change in energy.Both result in a change in the identities of elements.

Why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? Check all that apply.Chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.Chemical reactions involve changes to protons and neutrons in an atom; isotopes do not differ in protons or neutrons, and so they react the same way during chemical changes.Nuclear reactions involve changes to protons and neutrons in an atom; isotopes differ in neutrons, and so they react differently to these changes.Nuclear reactions involve changes to electrons in an atom; isotopes differ in electrons, and so they react differently to these changes.
