Answer:
Forms of carbon differ in the oceans.
Explanation:
Two different primary types of carbon exist in the oceans.
- Carbonates - organisms in the ocean absorb carbon dioxide and produce carbonates CO₃²⁻. Calcium and magnesium ions combine with carbonates to form <u>calcium carbonate</u> that make up the bulk of corals and seashells plus <u>magnesium carbonate</u>.
When atmospheric CO₂ dissolves directly into the seawater, carbonic acid is produced, that reduces the pH of seawater.
One of the earth's precious diverse ecosystems comprises of coral reefs. Coral reefs' body is made up of calcium carbonate. However, calcium carbonate acts as a buffer. That's why, as pH decreases, the dissolution of calcium carbonate (corals structure and seashells) increases. It results in a massive extinction of coral ecosystem.
Hence, we should not disturb the balance of nature.
Answer:
Options (2), (3), (4), and (7)
Explanation:
The factors that affects the number of deaths and the amount of damage caused by an earthquake depends upon the following things-
(1) Magnitude- The magnitude of an earthquake controls the amount of damage and loss of people. A high magnitude earthquake can cause greater damage in comparison to a low magnitude earthquake.
(2) Distance- The distance also plays an important role. When the distance from an earthquake is short, then the places nearby, at a certain radius gets affected very badly. Whereas, the places that are at a far distance, are not affected much by the earthquake.
(3) Depth- The depth of an earthquake depicts the epicenter distance. Shallow depth earthquakes are responsible for massive destruction. But, the deep focus earthquakes does not affect much unless it has a much stronger magnitude.
(4) Material that is used for construction of buildings- The type of materials that is used for construction purpose also is important. Weaker materials are easily broken down resulting in the collapsing of building. So, hard and resistant rock must be selected in order to maintain the stability of the buildings.
Thus, the correct answers are options (2), (3), (4), and (7).
It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water

Answer:
No
Explanation:
Consider why:
1. Remember, human rights are rights or entitlements every human should/ought to have, so whether they are won by large groups or by individuals they are still rights.
2. Also remember, a large group of people are in themselves individuals who came together forming a group, so in a sense victories won by the group was won by each individual affected by the victory.
