Answer:
coz the modern cells have a lot more complex structures which had evolved along time
The color change in the moth was proof of evolution due to the fact that whenever the Industrial Revolution occurred, it caused the moths to become a darker shade. The dark colored moths kept increasing until the pollution was reduced and the original, lighter colored moths started resurfacing
it has to do with one be more effective than the other.
The hypothesis devised in this study by the researcher is –
" White fly nymphs escape predation because of their translucent bodies."
In order to test this hypothesis, the researcher is required to conduct an experiment where two sets of white fly nymphs are formed and fed to their predators. The two set of subjects would be -
Set I – White fly nymphs with translucent bodies
Set II- White fly nymphs with translucent bodies coated with harmless dyes.
The number of predated flies in each set can be compared to deduce justification for assumed hypothesis.
Hence, option B is correct
Nostrils-nasal cavity- pharynx-larynx- trachea- bronchus-bronchiole- alveoli
