Answer:
Tiltmeters and strainmeters measure subtle changes in ground slope and shape at volcanoes. .
Explanation:
Measuring tiny changes in the slope angle or "tilt" of the ground and the shape or "strain" in the earth's crust are time-tested methods for monitoring volcano deformation caused by moving magma.
Acidity is determined using a pH indicator
Bacteriophages are viruses that infect and duplicate within a bacterium. Temperate phages (such as lambda phage) can keep reproducing using both the lytic and the lysogenic cycle.
SO.... Bacteriophages
I believe is the answer that you are looking .
Let me know if its right or wrong!!
Last one - Biodiversity is the diversity of species in an area, which makes an ecosystem better prepared for major changes
Explanation:
If one crop struggles to grow then there will be plenty of others to substitute it. If a prey animal is dying at a faster rate and harder to find, predators can have other prey options and so forth. Biodiversity makes it so ecosystems can get past change.
