False : Plants, algae and many species of bacteria can make their own sustenance through the process of photosynthesis. They harness sunlight to drive the chemical reactions in their bodies that produce sugars
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:
Option D. only about 1.5% of the oxygen carried in dissolved form.
Explanation:
Since the blood is a composition of two phases: Red Blood Cells (RBC) and Plasma, the transport of oxygen is carried out by both the phases further in 2 forms RBC water and dissolved oxygen in plasma.
RBC water and Plasma together carries aprroximately 2% ot the toatl oxygen where plasma alone carries about 1.5% of the dissolved oxygen in accordance to Henry's Law which follows that the amount of dissolved Oxygen in the blood is proportional to its partial pressure above the blood.
