I actually had a similar question on my test and this is the answer:
The reason the magnet loses its magnetic properties is is because when you drop the magnet or bump it against something, the domain can get bumped or dropped out of alignment.
Hoped this helped :)
Have a great day <span />
The answer is; true
These microbes are usually adapted to their environment and this is why they are found in virtually all ecosystems. You will find bacteria even at the bottom of deep ocean beds deep and in geothermal vents, hypersaline water and very cold regions (such as polar regions). Fungi which vary widely in size from microscopically small to the largest organisms such as mushrooms are also found in virtually all environments on earth. They are nonetheless different species of these groups adapted to their environments.

Answer
Ocean acidification results from the solubility of CO2 in oceans increasing the H+ concentrations, and depletion of bicarbonates concentrations.
Therefore, human activities which increases the concentration of CO2 in the atmosphere, will raise the atmospheric CO2 concentration. CO2 is constantly being absorbed by green plants maintaining its concentration through carbon cycle,Therefore massive deforestation which removes green plants, cutting down photosynthesis is one of human activities which raises CO2 levels of the atmosphere.The CO2 dissolves in the oceans to raise its acidic levels.Lower pH.
Another source is fossil fuels emissions which add more CO2 to the atmosphere.
Explanation:
Homeostasis is one way our bodies maintain its parameters within the normal range of values. We can say that it is key to life. When homeostasis fail, it can lead to diseases like hypertension and diabetes. In homeostasis, there will be stabilization of blood pressure as well as maintenance of its steady resting state. Take this scenario as an example, if a person exercises, there will be an increase of the heart rate, which will also result to higher blood pressure. The process of homeostasis will then accommodate the body through different mechanisms to make the decrease of the heart rate possible and at the same time reduce the high blood pressure. It is through homeostatis by which the normal body functions are maintaned in order to sustain life.
