Answer:
When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean’s pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact. In the past 200 years alone, ocean water has become 30 percent more acidic, faster than any known change in ocean chemistry in the last 50 million years.
Explanation:
Answer: Myocardial infraction can be defined as the condition which is caused due to absence of oxygen in major parts of the heart.
This also causes ischemia which occurs primarily and myocardial infraction occurs secondarily to this.
When, oxygen and nutrients from the blood reaches to the area which was deprived of oxygen results in inflammation and oxidative damage.
This is caused due to induction of oxidative stress rather than the normal functioning of the body.
They drill holes and bring up samples of rock and study how seismic wave move through the earth.
