Answer:
the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system
Explanation:
The human respiratory system is responsible for taking in oxygen-rich air, and they expelling oxygen-poor air. The respiratory system consists of lungs, which helps in the exchange of gases: Oxygen and carbon dioxide.
The statement ''the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system'' explains the change in oxygen concentration of the inspired air

Answer:
The correct answer would be - Dd Pp.
Explanation:
As it is given that tall D is dominant over dwarf d and smooth plant Pis dominant over pubescent p so the the genotype of dominant trait that is tall and smooth tomato plants would be DDPP
. similarly the recessive trait that is dwarf and pubescent plant would be ddpp
Thus, the cross between these would be -
DD PP x ddpp
And gametes would be - DP,DP, dp, and dp.
So, all the 16 offspring would have Phenotype would be heterozygous tall and smooth and DdPp genotype
.
Thus, the correct answer would be - Dd Pp.
