DNA because it tells each organelle their functions.
Answer:
C
Explanation:
In general, Gases are the most compressible and solids are the least compressible.
Glucose is absorbed by Na+/glucose symporter into the intestinal epithelial cells.
<span>
Symporter is located on the apical membrane of the intestinal epithelial cell and it <span>is used for uptake of glucose from the intestinal lumen into the cell (against the concentration gradient). One glucose molecule and two Na+ enter the cell via symporter. Na+ concentration gradient and the membrane potential (generated from the Na+/K+ ATPase in the basolateral membrane) enable the function of the symporter. Glucose leaves the cell via facilitated diffusion on the basolateral membrane of the intestinal epithelial cell and goes into the blood.</span></span>
Why are the oldest rocks on the ocean floor only 200 million years old while the oldest rocks on the continents are almost 4 billion years old?
Explanation: <em>The oldest oceanic crust is about 260 million years old. This sounds old but is actually very young compared to the oldest continental rocks, which are 4 billion years old. ... It is due to the process of subduction; oceanic crust tends to get colder and denser with age as it spreads off the mid-ocean ridges.</em>
