The area of the brain involved in production of speech is
a. broca s area
b. wernicke s area
c. the occipital lobe
d. the parietal lobe

Broca's  Area

Explanation: The human brain has four lobes such as frontal lobe, parietal lobe, occipital lobe, and temporal lobe. In the frontal lobe,  Broca's area is present. It is responsible for language production. If any damage or injury occurs in this area, there is a problem in speaking. Sometimes human being speeches are broken. The Broca's meaning is broken speech. The Wernicke's area is responsible for the understanding of the speech. It is present in the temporal lobe. But the Broca's area is meant for speech production.

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.
