Answer:
a identification key
Explanation: because it identifys you
The United Nations Conventions on the Law of the Sea (UNCLOS) stipulates that seabed area, which is not within the landmark of any particular country should be regarded as a common natural heritage. Consequently, any mineral found in such an area can be used by anyone.
However, because of the abundant presence of sea area, and the way national boundaries often conflict, coupled with the problem of illegal mining practices, such laws are difficult to enforce, and so these regulations are not standardized yet.
Some possible impacts of ilegal seabed mining are:
1. Destabilisation of oceanic systems.
2. It constitutes danger to the organisms living in the hydrothermal vents.
Answer: When using fossils approximate age by comparing it to similar rocks and fossils of known ages, is called relative dating.
Using that method we can determine the age of rock layers. That’s our way of dating them.
Hope this helps! ^^
Answer:
The living organisms must not reach equilibrium in the concentration of oxygen and carbon dioxide so that the Exchange of gases continues . Otherwise respiration and photosynthesis will stop.
Explanation:
- Gases move along the concentration gradient i.e. from their higher concentration to lower concetration.
- If living organisms reach a equilibrium of carbon dioxide and oxygen concentration, then The gases will not move in and out of the cells.
- This is because at state of equilibrium the concentration of gases on both side become equal and the movement completely ceases.
- If gaseous exchange in the body stops the process of respiration and photosynthesis in Plants and respiration in animal will completely stop.
