<span>The difference between plant cells and animal cells is that plant cells are surrounded by a cell wall wile animal cells are not. The existence of the cell wall is used for photosynthesis of plants because it is in the cell wall where the chloroplast is located. Plant cells do not have lysosomes which has an important function for waste disposal of animal cell.</span>
Answer:
b, a, d, c, e
Explanation:
The lac operon is called lactose operon is a cluster of genes with a promoter. The bacteria uses lactose as the source of energy by the proteins coded by genes. This is present in prokaryotes.
The regulatory gene codes for repressor protein. The repressor binds to lactose and prevent its binding to operator. In the absence of lactose repressor gets activated and binds with operator. Thus, RNA polymerase is prevented from binding the promotor. The transcription of genes inhibited. Thus correct order is b, a, d, c, e.
