Microorganism protect themselves against harmful UV light and visible light by using Iron minerals around themselves.
The iron minerals have unique properties in that they block damaging UV radiation while yet allowing organisms to utilise the portion of sunlight required for photosynthesis. UV rays kill cells by damaging their DNA. Two molecules of thymine, one of the bases that makes up DNA, react when exposed to light. The thymine dimer that results is extremely stable. The cell cannot perform its usual tasks if cellular processes are interfered as a result of an inadequate repair or unrepaired damage of thymine dimer.

Answer:
Plate boundaries
Explanation:
earthquakes move tectonic plates and plate boundaries
The entire population of microorganisms inhabiting an area, such as soil, humans, the large intestine, feces, or any part of the human body is known as a <u>microbiome.</u>
Microorganisms are those organisms that can be seen only through a microscope.
These are very small microscopic creatures that are hard to see with the bare eye and exist in colonial forms or as a single cell.
All bacteria, fungi, protozoa, and algae are microorganisms.
Some microorganisms are beneficial for humans while others have harmful and damaging impacts and also cause infections.

The majority of Earth's atmosphere contain 78% is nitrogen, The Nitrogen cycle is the geochemical cycle in which nitrogen is converted into multiple chemical forms. Nitrogen cycle occurs in terrestrial and marine ecosystem. Nitrogen can be converted through both biological and physical process. The processes that are involved in nitrogen cycle are fixation, ammonification, nitrification, and denitrification.
There is limited amount of nitrogen that is useful but <u>increase of fossil fuel combustion, use of artificial nitrogen fertilizer</u> have dramatically increased the amount of nitrogen in nitrogen cycle.
Answer:
First, the raised hammer has more potential energy since it has the potential to go higher or lower. Second, when you hit the hammer on the table, the stored potential energy is converted to kinetic energy as the hammer is falling. (It's the falling hammer that has kinetic energy)
Explanation:
Another example-When rolling a ball down a ramp the ball at its highest point has potential energy but when it rolls down the ramp it converts to kinetic energy
Hope this helps :)
