Answer:
Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.
Explanation:
The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.
The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.
Two possible consequences of not regulating marine mining are:
- <u><em>Destruction of the habitat of life forms present on the sea floor</em></u><em>, which endangers many species and even forces migration to more stable areas, with consequences on the food chains.
</em>
- <em><u>Extinction of marine species that inhabit the seabed</u></em><em>. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.</em>
Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.
Answer:
The correct answer is ATP and NADPH
Explanation:
During the light reaction, the light energy is absorbed by the chlorophyll pigment present in the thylakoid membrane which moves through different electron acceptors and allows the formation of NADPH and ATP.
This ATP and NADPH get utilized into the Calvin cycle during carbon fixation, reduction and regeneration steps. This utilization converts ATP and NADPH into ADP and NADP+. The energy released by them is used to fix carbon to produce organic compounds. Therefore the correct answer is ATP and NADPH.
Answer: answer
explain : [One glucose and oxygen ]
Answer:
To turn sugars into energy
Explanation:
- Mitochondria are main sites of aerobic respiration. They are miniature biochemical factories where food stuffs are completely oxidised to carbon dioxide and water.
- The energy (ATP) produced in the mitochondria helps to perform various energy requiring processes.
- Because of the formation of ATP in mitochondria it is called power house of the cell.
- Photosynthesis: Light reaction (in thylakoids), Dark reaction (in stroma).
- Storage of starch.
Answer: A. Inner Core
Explanation: The inner core is solid, the outer core is liquid, and the mantle is solid/ plastic. This is due to the relative melting points of the different layers (nickel - iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases. Hope this helps :) If not, I am sorry :( If it does, Your Welcome!
