Homework Answers
Ionic bond is formed when electron is completely donated to the non-metal by metal. Metal being more electropositive, it is easy for metal to form cation by donating electron whereas non-metal being more electronegative, it is easy for non-metal to accept electron from metal to form anion and as a whole and ionic bond.
So the transfer of an electron from metal to non-metal best describes the ionic bond.

Which of the following best describes what occurs during the electron transport chain? The diffusion of H+s provides the energy needed to make electrons move through the electron transport chain. Once the electrons reach oxygen, ATP is produced. O An H+ gradient is used to place oxygen at the end of the electron transport chain. The oxygen then pulls electrons towards it, which results in the synthesis of ATP. The energy of moving electrons is used to generate a proton...

QUESTION 40 Which best describes bacterial quorum sensing? A system that allows bacteria to transfer virulence factors from one bacterium to another by horizontal gene transfer. A system that allows bacteria to sense their own population density by communicating with each other by way of secreted chemical factors and behaving as a population rather than as individual bacteria. A system that enables bacteria to directly injecting bacterial effector molecules into the cytoplasm of the host cell in order to alter...

Which of the following best describes London dispersion forces. Question 1 options: the intermolecular forces that exist when ions from an ionic compound are attracted to the dipole of polar molecules in a mixture. involves molecular orientations in which the positive end of one dipole is near the negative end of another forces that exist only between molecules that contain hydrogen atoms bonded to highly electronegative atoms such as O, N, F. Interactions between temporary dipoles cause atoms to be...
