Which statement describes the transmission of mechanical waves?(1 point) They cannot travel through matter nor in a vacuum.

They can travel through matter, but not in a vacuum.

They cannot travel through matter, but they can in a vacuum.

They can travel through matter and in a vacuum.

They can travel through matter, but not in a vacuum.

Explanation:

The best statement that describes the transmission of mechanical waves is that they can travel through matter but not in a vacuum.

Mechanical waves require a material medium for their propagation. In the absence of such medium they are not transmitted. Examples are seismic waves, sound waves, water waves e.t.c

A type of wave than can be transmitted through a vacuum and through matter are the electromagnetic waves.

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
