Aseries of experiments, which are repeated over and over, seem to suggest that a scientific theory is incorrect. what does this most likely mean?

a. the experiments were faulty.
b. the scientist was manipulating the results.
c. the theory must be revised.
d. the results should be modified to agree with the theory.

The correct answer is option C. The theory must be revised.

The theory is the scientific explanation of a phenomenon, which explains the working and its causes. The experiments performed to give a theory must be replicatable and must produce the same result all the time. In case, the experiment according to the theory produces different result many times when performed by different scientists, then there must be some fault in the theory, then it need to be revised.

it will increase due to the time span

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.
