Bacterial cells use at least three different pathways for carrying out genetic recombination. one of these three pathways utilizes an enzyme complex called recbcd, which binds to breaks in dna and exhibits both helicase and single-strand nuclease activities. breafly describe a model showing how the recbcd enzyme complex may set.

answer; i believe the correct answer to the above question is ( friction)

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.

explanation:
