Explanation:
The negative impact of tourism on marine ecosystems be minimized using following methods :- Government should put restrictions on tourist visits on some specific marine tourists spots and only allow only specific people to visit that area at a particular time.- All the marine ecosystems should be cleaned regularly and throwing of garbage should be banned.- Proper management system should be implemented for the protection of marine ecosystems.- Endangered species and coral reefs should be handled using preventive measures by the government.

1000:1
The ratio of the volume of typical eukaryotic :prokaryotic cells is 1000:1
Explanation;
-Eukaryotic cells are generally much larger than prokaryotic ones and this difference in volume has several implications. One advantage is that bigger cells can afford to have more things stored in the cytoplasm such as organelles. This means it is not as costly to a eukaryotic cell to have structures taking up space. In a prokaryote, space is at a premium and anything not being used is pretty rapidly degraded.
-If the diameter of a typical eukaryotic cell is approximately ten times the diameter of a typical prokaryote, then it means the linear scale factor or the ratio of the lengths (diameter) is 10:1.
-The volume scale factor or the ratio of the volumes is got by getting the cube of the ratio of the length (diameter). Thus;
The volume ratio is (10:1)³ = 1000:1

Introduction
Carbon is a very important element to living things. As the second most common element in the human body, we know that human life without carbon would not be possible. Protein, carbohydrates, and fats are all part of the body and all contain carbon.
Carbon occurs in many forms on Earth and is found throughout the environment (Figure below). The element moves through organisms and then returns to the environment. When all this happens in balance, the ecosystem remains in balance too. In this section, let’s follow the path of a carbon atom over many years and see what happens.
Explaination:When your body breaks down food to produce energy, you break down protein, carbohydrates, and fat, and you breathe out carbon dioxide.
