Loss of biodiversity matters not only with regard to mammals or other vertebrates, but also microbes. What statement below would encourage a wide range of people to view microbes as worthy of discovery and protection from extinction?
A. Microbes may be the most sensitive to the next large extinction event.
B. Microbes may produce unique proteins useful in genetic research.
C. Microbes play a role in digestion.
D. Microbes are much greater in species number than any other taxa on Earth.

B. Microbes may produce unique proteins useful in genetic research

Explanation:

Biodiversity refers to the diversity of living beings present on Earth. The biodiversity is a very important component of the ecosystem as these living organisms are interlinked with each other. Therefore, the loss of biodiversity will affect the ecosystem.

When we look at the biodiversity a layman considers the living organisms which can be seen with eyes but the diversity also exists at the level of the micro-organisms.

The man-made activities are not only harming the macroscopic but also microscopic organisms. The microbes play an important role in our life like these days they are used by the scientific community to study the genetic and related fields like molecular biology. The microbes produce proteins that are consumed by humans.

Thus, Option-B is correct.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

the answers are a and c
