Each plant contains a branched system of tubes called xylem, which is responsible for water transport from the roots<span> (where it is taken up) to the leaves (where it is used in </span>photosynthesis<span>).
hope this answers your question</span>
<span>The answer is letter B.
Almost
all chemical reactions in life processes occur in solutions with water. It
is
the most abundant molecule found in living organisms. Most mammals, in fact,
are approximately 70% water by weight. About 2/3 of this water is present inside cells. The other 1/3 is present
outside cells (e.g in blood plasma or other body fluids).Without water the
proper transport and processes that occur with a cell will not efficiently
function therefore making the organism inefficient as well. <span> </span></span>
Answer:
muscle contraction increases interstitial fluid pressure and compresses the blood vessels within the active muscle. As a consequence, blood flow is highest when muscles relax between successive muscle contractions.
Explanation:
Answer:
does not change the identity of a substance
Explanation:
when a substance undergoes a physical change, the molecules move further apart but the chemical structure of the molecule does not change
