forests are important to today’s oceans‚ and they depend on the organisms that live within them‚ especially the sea otter. A keystone species is a species whose presence contributes to the diversity of life in its ecosystem. If a keystone species to an ecosystem were to go extinct‚ their ecosystem would suffer severally. In the case of the kelp forest the major keystone species is the sea otter. The reason that the sea otter

difficult. This is because most rigid flashing materials are hard to bend around an arch with tight curvature. If the arch span is less than about 3 ft (0.9 m)‚ one section of tray flashing can be placed in the first horizontal mortar joint above the keystone‚ as illustrated in Fig. 5b. For arch spans greater than 3 ft (0.9 m)‚ flashing can be bent along the curve of the arch with overlapping sections‚ as illustrated in Fig. 4. Alternately‚ a combination of stepped and tray flashing can be used‚ as

Keystone species are species of animals that other species and the entire ecosystem depend on. Sea otters and elephants both play major roles in their ecosystems‚ as they are both keystone species. Without these two species‚ their ecosystems would have drastic changes in the environment in which many organisms and species would not be able to survive. If the sea otters and elephants were to leave the ecosystem it would cause a domino effect. The domino effect would make other species disappear

Experiment 3: Cryoscopic Determination of Molecular Weight Aim: The primary objective of the experiment is to calculate the total molecular mass of the compound benzoic acid in a predetermined amount of cyclohexane. Introduction: One of the key concepts in this experiment is the term freezing point depression. The definition of this phrase is that when a solute is dissolved into a solvent‚ their collective boiling point will be less than that of the original boiling point of the solvent. This incidentally
