TEAS 7 SCIENCE(100% CORRET) LASTEST UPDATE 2024/25
1. A student investigating the importance of wavelengths above and below the visible
spectrum for photosynthesis sets up an experiment as follows over a 2-month period,
all with illumination at 1-meter distance from plants grown with the same sol and
watering conditions
❖ 3 Arabidopsis plant exposed to ultraviolet light (UV)
❖ 3 Arabidopsis plants exposed to infrared light (IR)
❖ 3 Arabidopsis plants exposed to white light
At the end of the experiment, she finds that the IR treated plants are scorched, the UV
treated plants have wilted, but the white light created plants are growing normally.
Which of the following statements is most likely to be correct?
o Three plants do not produce sufficient replications to draw a conclusion o
Wavelength of lights the only variable that has been changed between groups o
The wavelength of light does not affect photosynthesis o Infracted light contains
more energy than the other wavelengths.
2. A researcher collects high-resolution photographs of the earth taken from outer space
at annual intervals for the last decades. This data would be most useful to analyse
which of the following?
o Human movement during crises
