the respiration in human start from breathing.the oxygen is inhale and passes through larynx and reaches upto trachea and it goes in the bronchus.it is also divided into bronchoioles. it leads into lung
the bronchoioles that enter in the lung lead to small air sac called alveoli and it exchange gases and here exchange of gas occur and carbon dioxide is transported back to nostril through same passage and the canbondioxie is exhaled.in this way the process of respiration is completed
hope this helped..
Cross: AA × aa
F1 Progeny: Aa , Aa, Aa, Aa
Now, F1 Cross: Aa × aa
Progeny = Aa, Aa, aa, aa
Phenotypic ratio would be: (Agouti to smooth-haired) = (1:1)
Hope this helps!
A device that changes electrical energy into mechanical energy is a electric motor.
The choices can be found elsewhere and as follows:
<span>Osmosis
Active Transport
Passive Transport
Facilitated Diffusion
I think the correct answer is the second option. The process that would be necessary is active transport. </span><span>Transport of materials against the concentration gradient requires energy which is active transport.</span>
