To keep food from entering your lungs, the body's digestive and respiratory systems must work together.

I'm not sure if not sure what the question is but I'll take a stab and say it was a true/false. The answer is true.

Explanation:

There's a tiny flap of tissue and it covers the airway when we drink or walk. Sometimes it may spasm or contract late and this is why sometimes people say, "It went down the wrong pipe!" hope this helps.

mendel's first law states that during the formation of reproductive cells , pairs of hereditary factors for a specific trait separate so that offspring receive one factor from each parent.

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.
