Answer:
Environmental Science is an interdisciplinary course covering a wide variety of topics including biology, physics, geology, ecology, chemistry, geography, astronomy, meteorology, oceanography, and engineering. The course also considers ways in which human populations affect our planet and its processes. Of special emphasis is the concept of sustainability as a means of using resources in a way that ensures they will always be around us. The unifying concepts that tie the different areas of environmental science together are as follows:
Science provides a way to learn more about the world and influences how we understand it.
Energy conversions underlie all ecological processes.
The Earth is one interconnected system.
Humans change natural systems.
Environmental issues have a cultural and social context.
Human existence depends in part on increasing practices that will achieve sustainability
Explanation:
Answer:
the heart is separated into two sides so that it can carry out its function well. The right heart contains deoxygenated blood and the left heart with oxygenated blood. the two sides are separated from each other so that the blood from the two sides don't get mixed. this leads to effective oxygenation of the deoxygenated blood in the right heart through pulmonary circulation and effective oxygenation of the tissues in the different parts of the body by the oxygenated blood of the left heart through systemic circulation.
Explanation:
Answer:
Put the cut portion in vertical upward position and cover it with clean tissue or cloth.
Explanation:
At first to minimize the bleeding from wrist we need to raise the wrist up and then apply pressure by clean tissue or cloth. Wrap the tissue/clothe around the wrist. If blood is soaking through the material wrapped, don't remove the wrap but pot more tissues/cloths around the wrap and continue to apply the pressure. The hand should be kept raised at a level more than the level of heart of that injured person. Due to continuous pressure of the wrapping material the bleeding will stop in around 5-8 minutes.
