1 Question: Does temperature
affect plant growth?
Hypothesis:
IV:
DV:
Control:
Your group wants to determine
the effect of temperature on
the growth of bean plants. You
will grow ten plants at normal
room temperature: 20 degrees
C. You will grow ten more
plants at 30 degrees C. You
will measure the plants' heights
once per week to compare
growth.
Constants(3):
Jk

The temperature does effect the growth of the plants. If you kept them all at different temperature and the growth was different then the temperature is definitly a factor in plant growth

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
