Q: The attractive force between water molecules is what kind of reaction? Read this paragraph and choose the correct option from the provided answers: The attractive force between water molecules is a dipole interaction. The hydrogen atoms are bound to the highly electronegative oxygen atom (which also possesses two lone pair sets of electrons, making for a very polar bond. The partially positive hydrogen atom of one molecule is then attracted to the oxygen atom of a nearby water molecule (see Figure below ). Choices: - symmetrical reaction - aquatic reaction - diffusion reaction - dipole reaction A:
(Answer)
dipole reaction

Q: Though viruses are not considered living, they share two important traits with living organisms: they have genetic material and they can undergo what process? Read this paragraph and choose the correct option from the provided answers: Though viruses are not considered living, they share two important traits with living organisms. They have genetic material like all cells do (though they are not made of cells), and they can evolve. The genetic material of a virus can change (mutate), altering the traits of the virus. As the process of evolution has resulted in all life on the planet today, the classification of viruses has been controversial. It calls into question the very definition of life. Choices: - generation - sexual reproduction - learning - evolution A:
(Answer)
evolution
