diffusion is a critical process required for oxygen to leave the
alveoll of the lungs to enter the blood and for carbon dioxlde (a
waste gas) to leave the blood and enter the alveoll.
9. knowing what you know about how a substance travels in
diffusion, in order for oxygen to leave the alveoli and enter the
blood, there would be a (higher or lower ] concentration of
oxygen in the alveoli compared to the blood.
10. knowing what you know about how a substance travels in
diffusion, in order for carbon dioxide to leave the blood and enter the
alveoll, there would be a (higher or lower] concentration of
carbon dioxide in the alveoli compared to the blood.

11. explain your reasoning for questions #9 and #10.

✿   this landform has a high elevation and a high relief

✿   this landform is a mountain

answer; i believe the correct answer to the above question is ( friction)

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.

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.
