This is an isoelectronic series, which means that the number of electrons on each ion is the same. In an isoelectronic series, the nuclear charge increases with increasing atomic number and draws the electrons inward with greater force. The ion with the fewest protons produces the weakest attractive force on the ions, so it has the largest size. Oxygen has the smallest atomic number, so it has the fewest protons, and therefore will have the greatest ion size. Which of the following best expla...

The primary independent variable in this study was Manoshi membership, while the three reported dependent variables were the MNH practices. In this question, it is said that the presence of a CHW in the social network of those who were already Manoshi members was linked with improved MNH behavior. This implies that the presence of the CHW worker could be what facilitates the effects of Manoshi membership, making CHW presence a mediating variable. correct answer is B Aversive conditioning -...
