Answer:
Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.
Explanation:
Operon is the group of related genes and the operator and promoter sequences that regulate their expression. All the genes in an operon are expressed together and are under the regulation of the same promoter and operator sequences.
Operons consist of the genes that are involved in related metabolic pathways. For example, the genes that code for the enzymes of lactose catabolism are expressed together as lac operon. It allows simultaneous expression of the genes of lactose catabolism only when lactose is present in the medium. Similarly, these genes are inhibited simultaneously in absence of lactose by binding of repressor protein to the operator sequence.
Answer;
In plants, simple sugars are least likely to be linked together to form proteins.
Explanation;
Photosynthesis in plants generates simple sugars; that are either used by plants to generate energy during cellular respiration, or stored by plants in form of starch for future use.
These simple sugars are majorly carbohydrates which include glucose, fructose, and galactose, that are also called monosaccharides. They are the simplest form of carbohydrates and acts as building blocks of other carbohydrates (disaccharides and polysaccharides).
<span>Nucleotides, which are the building blocks of nucleic acids, consist of a phosphate group, a nitrogenous base, and a 5-carbon sugar. </span>
The correct answer is natural selection.
The process which drives to Darwin theory of evolution is a natural selection. Darwin theory is referred to as biological evolution which was developed by Charles Darwin which states that all types of species of organisms are known to develop and arise through natural selection.
Those small natural selection are either inherited variations which increases the ability of individual in order to reproduce , survive, and to compete.
In Darwin theory he included transmutation of species concept of evolution.
