Artist 52 [7]3 years ago

Mutation is the primary cause of all genetic variation. Mutation is important as the first step in evolution, as it produces a new sequence of DNA for a particular gene, producing a new allele. Recombination, through intragenic recombination, may also generate a new DNA sequence (a new allele) for a particular gene.

Nataly_w [17]

Answer:

The correct answer is ''the mechanisms for coordinating subunits.''

Explanation:

Integration mechanisms are explicitly defined to coordinate subunits. In turn, are divided into structural and non-structural mechanisms. Structural integration mechanisms coordinate activities and are usually linked to specific management positions or bodies. The non-structural integration mechanisms, for their part, are characterized because they do not create organs or positions, but they constitute a relevant complement to the structural mechanisms, facilitating the organization of work. Informal integration mechanisms or those aimed at facilitating informal relationships are the simplest and easiest to use. Individuals face a certain situation and, spontaneously, communicate with each other. If no further coordination is required, informal mechanisms may be sufficient
