Answer:
How cloning works: In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed. ... This young animal is referred to as a clone.
Basics of cloning:
Isolation of target DNA fragments (often referred to as inserts)
Ligation of inserts into an appropriate cloning vector, creating recombinant molecules (e.g., plasmids)
Transformation of recombinant plasmids into bacteria or other suitable host for propagation.
Screening/selection of hosts containing the intended recombinant plasmid .

Answer:
Biotic factor
Explanation:
Biotic factors are part of factors that determines the nature of the ecological system. They can either be living or dead organisms. Because they are considered to possess lives or had formerly existed, they are found in the biosphere and can reproduce.
Hence, to predict how the population of one species affects and is affected by the population size of another species or by its interactions with some abiotic factor, like rainfall. The ecological model uses a BIOTIC FACTOR.
This is because it is the interaction of the biotic and abiotic factors that determines the nature of the ecosystem.
