James is working with the lac operon of Escherichia coli (E. coli). He places the bacteria on a plate of growth media. The lac Operon of E. coli is shown.

Based on the current understanding of this operon, which hypothesis would be useful for James to test?
Addition of allolactose to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose.
Removal of the RNA polymerase molecule should increase the amount of bacterial growth on the plate.
Decreasing the amount of allolactose in the bacterial growth media should increase the rate of bacterial growth.
Increasing the rate at which RNA polymerase acts will inhibit bacterial growth.

Dominance the dominant allele doesn’t fully mask or hide the recessive. for example, a red carnation with a white carnation will produce a carnation. one gene one trait. well most of the time than one gene controls a trait. we are all different but genetically speaking we are % similar with regards to genetic makeup.

Part a - prefixes, roots, and suffixes match these prefixes, suffixes and roots to their meanings. phospho- angio- -uria -tropic -phag- a. the word root means blood or lymph vessels. b. the word root means urine. c. the word root means feeding or eating. d. the word root means phosphate or phosphorus. e. the word root means attracted specifically to the specified organ or tissue. part b – match these vocabulary terms to their meanings. gonadotropic polyuria angiotensin ii polyphagia phosphodiesterase upon the release of renin, is produced and stimulates vasoconstriction and the release of aldosterone. fsh and lh are examples of hormones, which target the ovaries or testes. an enzyme that degrades second messengers like camp or cgmp is . overproduction of urine, or , is a sign of diabetes mellitus. overeating, or , is a sign associated with diabetes mellitus.
