If an animal cell suddenly lost the ability to produce gtp, what might happen to its signaling system? a.)it would not be able to activate and inactivate the g protein on the cytoplasmic side of the plasma membrane. b.)it would be able to carry out reception and transduction but would not be able to respond to a signal. c.)it would use atp instead of gtp to activate and inactivate the g protein on the cytoplasmic side of the plasma membrane. d.)it would employ a transduction pathway directly from an external messenger.

In german cockroaches, curved wing (cv) is recessive to normal wing (cv+). bill, who is raising cockroaches in his dorm room, finds that the frequency of the gene for curved wings in his cockroach population is 0.6. in his friend joe’s apartment, the frequency of the gene for curved wings is 0.2. one day joe visits bill in his dorm room, and several cockroaches jump out of joe’s hair and join the population in bill’s room. bill estimates that, now, 10% of the cockroaches in his dorm room are individual roaches that jumped out of joe’s hair. what is the new frequency of curved wings among cockroaches in bill’s room? 0.69 0.4 0.5 0.31 0.20
