Answer:
Agriculture
Explanation:
Genetic engineering can be defined as the use of genetic techniques aimed at modifying the genome of living organisms, thereby being used to develop Genetically Modified Organisms (GMOs). In the USA, genetic engineering methodologies have been used in agriculture to improve crop yields and reduce costs (for example, by reducing the need to use pesticides). Some of the most important genetic engineering techniques that nowadays are being used in agriculture research include biolistic transformation, <em>Agrobacterium</em>-mediated transformation, the CRISPR-Cas9 genome editing system, etc.
Species is the basic unit of classification denoted by a unique two-part scientific name.
<h3>What is meant by species? </h3>
Species is a name given to a group of organisms which have similar individuals. They are capable of reproducing among themselves and thus exchanging genes among themselves.
Species is the lowest of taxa and is thus the most basic unit of classification. Genus is the next taxonomic rank of the next taxa on the hierarchy of classification.
It is estimated that on earth, there are 8.7 million species living currently. This concept of species is from the times of Aristotle.
Therefore, species is the basic unit of classification denoted by a unique two-part scientific name.
