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:
C
Explanation:
C represents the Oral Groove which is where the food intake is
Acetyl CoA is a feed forward activator of the enzyme <u> pyruvate carboxylase</u> ensuring sufficient oxaloacetate for the citric acid cycle to continue.
<h3>Why does acetyl-CoA stimulate pyruvate carboxylase?</h3>
Acetyl-CoA selectively activates pyruvate carboxylase. When acetyl-CoA concentrations are high, organisms use pyruvate carboxylase to divert pyruvate from the TCA cycle because acetyl-CoA is a crucial metabolite in the TCA cycle that generates a lot of energy. The production of more oxaloacetate is triggered by an excess of mitochondrial acetyl-CoA.
Acetyl coenzyme A, often known as acetyl-CoA, is a crucial component in metabolism and is involved in numerous metabolic processes. Its major job is to transport the acetyl group's carbon atoms to the Krebs cycle, where they can be oxidized to produce energy. When there is an abundance of acetyl CoA available, the mitochondrial enzyme pyruvate carboxylase (PC) catalyzes the conversion of pyruvate to oxaloacetate.
