a. Water is made up of one molecule of hydrogen and two molecules of oxygen
b. Water dissolves polar and ionic compounds
c. Solid water is more dense than liquid water

11. 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 soil and
watering conditions.
3 Arabidopsis plants 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-treated plants are growing normally.
Which of the following statements is most likely to be correct?
a) Three plants do not provide sufficient replications to draw a conclusion.
b) The wavelength of light does not affect photosynthesis
c) Infrared light contains more energy than other wavelength
d) Wavelength of light is the only variable that has been changed between groups

the human heart to an organ?

b. The adhesive force with the glass are greater than the cohensive force
c. Glass has a higher density than water
d. The cohesive forces with the gas are greater than the adhesive forces.
14. Which of the following statements does not accurately describe water molecules?
A) Each of the hydrogen atoms is linked to the oxygen atom by a covalent bond.
B) Hydrogen bonds link hydrogen atoms in one water molecule to oxygen atoms
in another molecule.
C) Oxygen atoms in a water molecule are negatively charged and hydrogen
atoms are positively charged.
D) The water molecule has a linear arrangement of atoms because the hydrogen
atoms repel each other.
15. Which of the following statements does not correctly describe water
properties?
A) Cohesion reflects the ability of hydrogen bonds to hold water molecules
together.
B) Cohesion is visible in the water's surface tension.
C) Increasing the temperature of water increases the surface tension.
