Which explanation explains why the Northern Hemisphere gets more direct sunlight in the Summer?

Probably too late answering this.

I don't know if they gave you answer choices, but something like:

"The way the earth is tipped on its axis in the summer has the Northern Hemisphere most closely angled to face the sun"

is what I would say.

explanation:

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.
