Answer:
<u><em>Proteins</em></u><em>:</em> used in facilitate transport across membrane
<u><em>Carbohydrates</em></u>: used to drive cellular respiration
<u><em>Lipid</em></u>: composes the cell membrane
<u><em>Nucleic acid</em></u>: used to create identical daughter cells in mitosis
Explanation:
A. In the cell membrane, transport proteins or channels are present which selectively allow the transfer of molecules. This is why the cell membrane is also known as a selectively permeable membrane.
B. In cellular respiration, which takes place in mitochondria, glucose (carbohydrate) is used to generate ATP molecules.
C. The cell membrane is composed of a lipid bilayer that contains protein channels. This makes the membrane insoluble in water and maintains the integrity of the cell.
D. The nucleic acid is the hereditary material that can replicate and transfer genetic information to the next generation.
D) if the tubes of the tracheal system in insects were longer, this would cause oxygen to reach the cells more slowly due to the distance factor
I would say B, <span>differ greatly between single solar systems. As we all know, I believe this is the only planet with life, but there might be many out there, too. Each planet should have very different characteristics unlike ours. So it may vary.</span>
