A threat to biodiversity. The growth and reproduction of microorganisms reduce the dissolved oxygen content of the water body. The Interactive Effects Of Stratospheric Ozone Depletion Uv Radiation And Climate Change On Aquatic Ecosystems Photochemical Photobiological Sciences Rsc Publishing Doi 10 1039 C8pp90062k However oxygen availability in these systems is threatened by global warming and excessive input of nutrients such as from agriculture and wastewaters known as eutrophication. . Thus excess organic material in lakes and rivers can cause eutrophic conditions which is an oxygen-deficient situation that can cause a water body to die. The resulting dead fish and other aquatic species degrade the water quality and cause unpleasant odors. Marine life depends on the dissolved oxygen for survival and its absence may negatively impact aquatic life. When the dissolve oxygen reaches hypoxic levels the animal and plant specie...
Live sheep were injected with a poison that would kill coyotes. Understand how emotions such as fears and anxieties can be learned. Classical Conditioning Psychology questions and answers. . In a study African lions were conditioned to dislike the taste of beef. This is done to keep lions from preying on cattle which should in turn prevent farmers from killing the lions. Response caused by the conditioned stimulus. The sheep ranchers learned to shoot more accurately through reinforcement. Classical conditioning is a type of learning in which an unconditional stimulus is paired with a neutral stimulus leading to a conditioned response. Classical conditioning can be used to support wildlife conservation efforts. A reflexive reaction triggered by an unconditioned stimulus is a n unconditioned response. Respondent conditioning is best described as occurring in three phases. Sheep were classically conditioned t...
Igneous rocks are molten rocks expelled as lava that has cooled and become solid. They can form both underground and at the surface. What Is The Difference Between Igneous Sedimentary And Metamorphic Rocks Pediaa Com Igneous rocks are rocks that formed directly from magma and can form either in the earth or on. . Sedimentary rocks originate from weathering of igneous rocks. Non-foliated rocks however lack this visual characteristic. The birth of the term is related to ignis which is in the Latin language fire. All three rock types - igneous sedimentary and metamorphic - make up a portion of the rock cycle. Igneous rocks are formed from molten material that solidifies. Regarding the difference between igneous and metamorphic metasomatism the following link might be helpful. In contrast nonfoliated metamorphic rocks do not contain minerals that align during metamorphism and do not appear layered. Metamorphic...
