Which must be kept in mind when determining if an explanation is correct?
MatroZZZ [7]

Answer:

C. that there may be more than one way to interpret data

Explanation:

When determining if an explanation is correct you must always remember that there may be more than one way to interpret data. Depending on the context that the explanation is being used in or who is reading it, the explanation may be interpreted in two completely different manners which may be far off from the original intended explanation. This can therefore completely nullify or maybe even expand the original determination.

Papessa [141]
<span>The answer to this question would be: tissues; decrease

Oxygen is delivered to the tissue by the heart. It will be unloaded in the tissue, causing the oxygen level in the blood to be decreased. After that, the blood also picks up the carbon dioxide so its level will be increased. 
In lungs, the carbon dioxide will be unloaded and oxygen will be loaded back into the blood.</span>

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. :)

mart [117]

Answer:

B. Mitochondria

Explanation:

  • Mitochondria are known as the power house of the cell. They are the sites of cellular respiration that breaks down glucose into energy molecules such as ATP and energy storage molecules such as NADH and FADH2.
  • In this scenario, since the cell's energy levels fall and metabolism ceases, the organelle most likely affected is the mitochondria.
  • If mitochondria are affected, glucose will not be metabolized to ATP and the cell will not have sufficient energy for cellular functions.
