How does the presence of cosmic microwave background radiation support the big bang theory? Check all that are true.

-It shows that here is a faint, leftover energy that is coming from all directions of the universe.

-It shows that the universe used to be smaller with a uniform temperature.

-It shows that the universe is coming back together and will collapse in a massive black hole.

-It shows that all matter and energy in the universe is accelerating.

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.
