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:
By the size and shape of the organisms.
Explanation:
C. albicans isn't a bacteria, it's actually a fungi. Therefore, there will exist significant differences between the bacteria normally found in the vagina, and the fungi that can be causing an infection. Fungus are, usually, bigger than bacteria. Also bacteria have special shapes, like bacillus and spirils, which fungus don't.
Answer:
The correct answer is B transcription factors.
Explanation:
Transcription factor are specific regulatory protein also known as sequence specific DNA binding proteins which regulates the process of transcription in eukaryotic cell.
Transcription factors may either turn on or off the expression of a particular gene to ensure that they are expressed in right cell along with perfect amount and manner.
Transcription factor such as helix turn helix ,leucine zipper, zinc finger play an important role in regulating the activity of many proteins such as DNA ploymerase, helicase
