Which of these is a direct impact of excess nitrates coming from agricultural runoff into a freshwater ecosystem? a) reduction of dissolved oxygen, resulting in the decrease of fish species. b) reduction of biological oxygen demand, resulting in the decrease of algal populations. c) increase in dissolved oxygen, resulting in increases of fish populations that feed on the nitrates. d) increase in biological oxygen demand, resulting in the increase of biodiversity for producers and consumers.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.

the answer is 100% density i've answered this question before and done the quiz myself.
