◉ Dependent variable. Answer: Variable is the consequence of the
experiment; researchers measure this variable throughout the
experiment.
◉ Control variable. Answer: Variables that are kept constant
◉ Larger. Answer: When researchers interpret results, they have to
consider if the outcome is significant or very unlikely to occur by
chance or random events.
The ___________________ the number of individuals or sampling size, the
more reliable the results.
◉ Large. Answer: When researchers interpret results, they have to
consider if the outcome is significant or very unlikely to occur by
chance or random events. Data obtained from a __________________
sample size is better able to show results that are significant.
,◉ solvent ... solute. Answer: You add sugar to water, and the sugar
dissolves. Thus the water is the _______and the sugar is the _______ .
◉ Element. Answer: Carbon is an
◉ Molecule. Answer: Atoms are bound together into a______________
◉ Covalent bond. Answer: a shared pair of electrons
◉ Ionic bond. Answer: electron transfer from one atom to another,
resulting in an attraction between oppositely charged ions
◉ Hydrogen bond. Answer: electrostatic attraction between areas of
molecules with opposite partial charges
◉ Covalent. Answer: _______________ bonds are the strongest
◉ Hydrogen. Answer: ________________ bonds are the weakest
◉ Ionic. Answer: ______________ are the middle of the strongest and
weakest bond
◉ Cohesion. Answer: Water molecules binding to each other is called
,◉ Adhesion. Answer: water molecules binding to other molecules is
called________________
◉ Polar. Answer: Water molecules form hydrogen bonds because
water is
◉ Polar. Answer: Water can bind to the walls of these cells because
they are
◉ Adhesion. Answer: When water binds to the walls of the cells, this
is called
◉ Cohesion. Answer: Water molecules within these cells will also
bind to each other. What is this called?
◉ Solution. Answer: Dissolving sugar in water makes a
◉ Solute. Answer: When dissolving sugar into water, The sugar is the
◉ Solvent. Answer: When dissolving sugar into water, The water is
the
, ◉ Solutes. Answer: As water moves up the plant, it carries matter
with it (such as nutrients and some hormones). What are these
materials called?
◉ Surface tension. Answer: What characteristic of water allows this
paperclip to float on the surface of the water.
◉ Mercury is not as adhesive as water.. Answer: Why does mercury
(Hg) not travel as far up the capillary tube as water does?
◉ The water is still adhering to the xylem walls, but the water
column is no longer continuous.. Answer: If the plant gets too dry,
the water column can break. This creates an air bubble in the xylem.
What happens to the water when the air bubble forms?
◉ Surface tension. Answer: What force is found at the interface
between the air bubble and the water in the xylem?
◉ Thicker. Answer: _____________ tubes are able to transport more
material.
◉ Thicker tubes. Answer: ___________________ are more likely to form
air bubbles. This is because the smaller diameter tubes can maintain
