Answer: Genetically engineered crops have an advantageous gene from another organism inserted into their genome.
Answer:
Option (4).
Explanation:
Lac operon is present in E.coli that regulate the metabolism of lactose in the bacteria. Lac Operon consists of three genes : Lac Y, lac Z and lac A, an operator and a promoter.
I+ P+ Oc Z− Y+ / I− P+ O+ Z+ Y− , in this case inducer is present, promoter is present, constitutive region and the gene lac Z and lac Y indicates the Z and Y. The permease enzyme will made in the presence and absence of lactose due to the presence of I+ P+ Oc in the cell but beta galactosidase is only made in presence of lactose as Y− gene is present in the diploid cell.
Thus, the correct answer is option 4.
The organs that work together is called systems. It is a group of parts or organs that interact and work together for a common purpose or function. Each of the parts seems to depend to each other in order to achieve their shared functions and goals. When one of the organs in a system becomes dysfunctional, automatically the other parts cannot function as effective as they were during those times that everybody's in good condition becaus the condition of one organ in the system directly affects the others too.
