What is the sensitivity of the microammeter?
Berapakah kepekaan mikroammeter itu?

100 micro-ampere

Explanation:

The sensitivity of an ammeter is the current required for the ammeter to reach its maximum reading or to cause maximum deflection of the ammeter.

As the relative amount of current required to cause maximum deflection of an ammeter is lesser, the sensitivity of the ammeter is said to be higher or the ammeter is said to be more sensitive

Therefore, given that the maximum reading on the given microammeter is 100 μA, the current required to cause the maximum deflection an thus the sensitivity of the ammeter is 100 micro-ampere.

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”.
