TEAS 7 SCIENCE (97% Correct)
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 UVtreated
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
, Davis Craig | Beststudy Academics (/)
o Migration patterns of large whales
o Weather patterns during hurricanes
o Deforestation in the rainforest
3. The shortening of a sarcomere in skeletal muscle is directly due to the interactional of
which of the following?
o Acetylcholine and acetylcholinesterase
o Pepsin and pepsinogen
o Myosin and actin
o Dynein and kinesin
4. Mutations in which of the following types of cells can be inherited by offspring?
o Ovarian
o endocrine
o neural
o muscle
5. Which of the following parts of the central nervous system releases chemicals that
regulate the pituitary gland?
o Hypothalamus
o Cerebellum
