This date refers to the 23rd of July Revolution where Egypt was granted independence from it's dominion status under the British.

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:
The probability of children who have both a cat and a dog is 63/100 or 63%
Explanation:
45/100 or 45% of the children already have a cat so you would add that to the amount of kids who already have a cat and a dog (18%)...Therefore 63% of students have a cat already may also have a dog.
