Answer:

The given statement is true.

Explanation:

A virus refers to a microscopic particle, which can infect the biological organism's cells. Viruses possess the tendency to replicate themselves only by infecting a host cell, that is, within the cells, thus, it cannot multiply on their own.  

At the most fundamental level, the viruses comprise genetic substance constituted within a protective protein coat known as a capsid. The prevalence of both the genetic substances and the presence of protein differentiates them from another virus like components like viroids and prions.

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.
