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:

  1. <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>
  2. <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.

The origin of congenital adrenal hyperplasia occurs when circulating cortisol levels
LuckyWell [14K]
The origin of congenital adrenal hyperplasia occurs when circulating cortisol levels are low.
Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease which results from mutations of genes for enzymes involved in the biochemical steps of production of mineralocorticoids, glucocorticoids or sex steroids from cholesterol by the adrenal glands (steroidogenesis). <span>Low cortisol production results in rising levels of ACTH (adrenocorticotropic hormone) because cortisol usually inhibits ACTH production. This increased ACTH production induces overgrowth (hyperplasia) and overactivity of the steroid-producing cells of the adrenal cortex.</span>
