a polar molecule The shape of a water molecule and its polarity make hydrogen bonding possible, A hydrogen bond is a weak attraction between a slightly positive hydrogen atom and a slightly negative atom. (They are partial charging) * Can occur between atoms of different molecule or within the same molecule * A single hydrogen bond is easily broken while multiple hydrogen bonds are collectively quite strong. * Help to maintain the proper structure and function of complex molecules

CASE STUDY: HOW HUMANS HAVE AFFECTED THE ANTARCTIC FOOD WEB Although the icy waters around Antarctica may seem an inhospitable environment, a complex food web is found there. The base of the food web consists of microscopic, photosynthetic algae present in vast numbers in the well-lit, nutrient-rich water. A huge population of herbivores—tiny shrimp like krill—eat these marine algae. Krill, in turn, support a variety of larger animals. A major consumer of krill is the baleen whale, which filters

based on evolutionary perspective. He thought that ethology (study animals in their natural habitat) has lot to do and in common with maternal care. He found that some species of birds when first hatched follow the first moving object they see and keep follow it after that. This is called Imprinting. The idea of the theory imposes that the infant would show imprinting to their own mother who would then explain the strong attachment/bond between the infant and caregiver/mother.
