DENIUS [597]

Answer:

C. experimental

Explanation:

Experimental variables are the variables that are changed during the experiments to observe the effects of these changes. An experiment usually has one or more experimental variables. An experimental variable that is changed to know its impact on some other variable is called the independent variable.

In the given experiment, goldfishes were exposed to various temperature conditions to observe the effect of temperature on respiration. Therefore, both temperature and respiration rate are the experimental variables here.

9. a) How does hydrogen bonding help the transport of water in plants?
grigory [225]

Answer:

Water has a high Cohesion because of Hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it.

Explanation:

Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

Plants obtain the hydrogen they need from water molecules. Don't try to feed your plant hydrogen gas -- your plant wouldn't know what to do with it if you did. As long as they have water, plants can readily obtain all the hydrogen they need. :)
