Answer:
Yes
Explanation:
<em>The chloroplast is an organelle through which photosynthesis takes place. While the light reaction takes place in the thylakoid membrane of the chloroplast, the light-independent reaction or the Calvin cycle takes place in the stroma of the chloroplast. </em>
I believe its C because it seems the most reasonable.
The active site is complementary to its substrate due to its specific 3D structure. The substrate fits in to one specific active site so an enzyme will only bind to one substrate. They are SPECIFIC. Lock and key theory.
Answer:
D (Swell and Burst)
Explanation:
Pure water contains a very low concentration of solute materials, hence it is regarded as HYPOTONIC. Since the red blood cell contains intracellular fluid that contains more solutes than the extracellular pure water it is placed in, it is said to be HYPERTONIC in comparison with the pure water.
This difference in concentration between the extracellular solution (pure water) and the intracellular fluid (red blood cell) called CONCENTRATION GRADIENT facilitates the movement of water by OSMOSIS. Osmosis is the process whereby water moves across a semi-permeable membrane from a region of low solute concentration to a high solute concentration.
Based on this osmotic gradient, water moves from the extracellular solution into the cell, causing it to swell and eventually burst as a result of excessive water intake.
