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
A compound of a covalent or ionic bond
The correct answer is sympathetic nervous system.
In the given case, the harry is experiencing stress, which provokes the flight and fight syndrome. The sympathetic nervous system causes the release of adrenaline and noradrenaline causing change in physiological responses. During the flight and fight response, a hyperarousal occurs, which leads to the change in physiological responses. It causes the increased heart beat, increased blood pressure, anxiety, increase in pulse, increased sweating etc.
