OMG PLS HELP ME I WOULD SO APPRECIATE IT 80 POINTS Scenario

The global population has increased immensely over the last two centuries. Humans use fossil fuels to do a variety of tasks from heating their homes to travel to production of everyday products. As the human population has increased, so have the global fossil carbon emissions.
Write a scientific explanation that describes total world carbon emissions in 2050 if the world’s population decreases to five billion people.
Claim:

Evidence:

Reasoning:

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.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.
