It is true that legislation has been ineffective at preserving coral reefs. As a result, there have been fewer and fewer coral reefs, which in turn results in fewer fish.
Answer:
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
Explanation:
Algae produces a estimated 30-50 percent of the net global oxygen .
Protons are represented as the atomic number.
Mutualism is a type of parasitism which is defined as a relationship which evolved between two species, where both species benefit. Mutualism can be between plants or animals, or both. Based on protection from enemies, mutualism are common in tropical ecosystems.
