An amino acid is synthesized by the prokaryote, e. coli. the genes for the enzymes responsible for synthesizing this amino acid are encoded in an operon. the operon is regulated by a repressor. when the amino acid binds to the repressor, the repressor changes shape so it can bind to the operator. which of the following statements is true?

What are chlorofluorocarbons made of

Ascientist and her team counted 200 individual deer in an area of 10 square kilometers. what is the population density?

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
