Answer:
Atmosphere, plant, animals, fossil fuels.
Explanation:
Carbon Is the essential elements needed for life.
Carbon cycle is the movement of carbon from the atmosphere to the Earth.
Carbon move in the carbon cycle and start from the atmosphere.
In the atmosphere, carbon react with oxygen and it is inform of carbon dioxide. Plants use the carbondioxide along with water,and uses light energy from the sun to produce carbohydrates through a process of photosynthesis.
Animals get carbon from plants after consuming plants.
During respiration, carbon atoms are released to the atmosphere.
Some human activities like burning of fossil fuels releases carbon to the atmosphere.

Site-specific recombination systems all of the choices are correct i.e.
A. do not depend on extensive nucleotide sequence homology.
B. depend on enzymes that are often specific for sequences within the host.
C. are features of some viruses.
- An exchange between two specified sequences (target sites), either on the same DNA molecule or on two separate DNA molecules, is known as site-specific recombination.
- DNA sequences may be integrated, excised, or inverted as a result of the exchange.
- A site-specific recombinase that can work by itself or with the aid of additional components or enzymes shapes the DNA target during recombination.
- The recombinase is chemically bonded to the ends of the intermediate DNA after DNA breakage at the recombination site; when this process is reversed, the intermediate DNA is resealed to form the recombinant and the recombinase is released.
- During this recombination process, neither replication nor repair are necessary.

Answer:
To electromagnetic radiation can be harmful depending on the frequency of radiation, which can range from microwaves that raise tissue temperatures, infrared radiation that produces heat and burns, x-rays can cause problems such as mutations associated with cancer and cell death , similar to ultraviolet radiation that can range from darkening the skin to promoting the appearance of cancer.
Among the beneficial effects, voltages similar to those produced by the connective system have been developed, to improve the treatment of different musculoskeletal diseases, also some radiation show benefits to treat some types of cancer, they are also used for sterilization of medical instruments or places requiring to be free of bacteria, x-rays are used as diagnostic means for studying bone and related injuries, radiation in the form of laser allows surgical procedures.
