<span>Mutagen is an agent that causes DNA mutations. UVA radiation penetrates
deep into the skin and acts as a mutagen. UV light is the most common source of
radiation that affects DNA, but it is a weak radiation and it penetrates only
the surface cells of your skin.</span>
Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks.
The global carbon cycle is now usually divided into the following major reservoirs of carbon interconnected by pathways of exchange:
- The atmosphere
- The terrestrial biosphere
- The ocean, including dissolved inorganic carbon and living and non-living marine biota
- The sediments, including fossil fuels, freshwater systems, and non-living organic material.
- The Earth's interior (mantle and crust). These carbon stores interact with the other components through geological processes.
The carbon exchanges between reservoirs occur as the result of various chemical, physical, geological, and biological processes. The ocean contains the largest active pool of carbon near the surface of the Earth.[3] The natural flows of carbon between the atmosphere, ocean, terrestrial ecosystems, and sediments are fairly balanced so that carbon levels would be roughly stable without human influence.

Incomplete Dominance would mean neither parent has full control.
Answer:
The correct answer is d. differential media
Explanation:
Differential media are used to distinguish between two microorganisms that are closely related. Differential media have some special and specific ingredients or indicators and nutrients which is used to differentiate between two different strains of bacteria by physical appearance like color.
For example, blood agar is the differential media that differentiate between the micro-organism who can lyse the blood cell and who cannot lyse blood.
So differential media allow us to grow both the organism but differentiate them on the basis of physical appearance like color, therefore, the correct answer is d. differential media.
