Answer:
Environmental Sciences is a multidisciplinary academic field that integrates biological, physical and information sciences for the study of the environment and solutions to environmental problems. These sciences include physics, ecology, zoology, biology, chemistry, mineralogy, oceanography, geology, soil sciences, atmosphere sciences and geography. The environmental sciences emerged from the fields of natural history and medicine. Today, they allow an integrated, quantitative and interdisciplinary approach to the study of environmental systems.
Related areas of study include environmental studies and environmental engineering. Environmental studies integrate social sciences to understand human relations, perceptions and policies regarding the environment. Environmental engineering focuses on design and technology designed to improve the quality of the environment. Environmental problems almost always include the interaction of physical, chemical and biological processes. Environmental scientists work on topics such as understanding ground processes, assessing alternative energy systems, controlling and mitigating pollution, managing natural resources and the effects of global warming, applying systemic analyzes to environmental problems.
Environmental sciences became an active field of scientific research in the 1960s and 1970s, due to the need for a multidisciplinary approach to analyzing complex environmental problems, the emergence of various environmental laws requiring specific research protocols, and increasing public awareness. the need for action to solve environmental problems.
Answer:
low level of calcium would result in fewer signals sent between pre and post synaptic cells.
Explanation:
The calcium has a main role in signal transmission mechanism and here is the mechanism :
1-the impulse reaches the synapse (depolarization which is a voltage change).
2-the voltage gated calcium channels open and let calcium flow into the cell.
3-the calcium causes the synaptic vesicles to rupture and release chemical transmitters which cross the synaptic cleft and finally bind to receptors on the post synaptic cell (transmitting the signal)
so it's obvious that if calcium concentration decreases, the signal transmission also decreases.
Your answer would be the second one B
