The seven-spotted cockroach is a nocturnal species that burrows under leaf litter during the day. The pattern on the exoskeleton of the adult seven-spotted cockroach is similar to that of the
carnivorous six-spotted ground beetle. This beetle has the ability to spray a chemical irritant at its
attackers. The mimicry of the ground beetle's pattern helps the seven-spotted cockroach survive
because it
О
A. is more visible at night
o B. can attract more potential mates
C. is less likely to be eaten by a predator
D. can better compete with beetles for food

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.
