A group of students is walking in the park, and one of them takes a picture of a pollen grain that is being blown by the wind. What caption can the student use for this picture? gene mutation in action gene flow at work genetic drift as it happens natural selection in progress

Pls me i need this ! each cell has genes activated depending on it's job and what kind of cell it is. it is the presence of that causes the repressor protein to fall off and unblock the gene on the lac operon. if a gene is turned on then it is being an additional circular chromosome found in some bacteria that is used in genetic engineering.
