Answer:
Gaseous exchange
Explanation:
In terrestrial plants, gaseous exchange occurs mainly in leaves and to a lesser extent in the roots and stems. In leaves, the structures involved in gaseous exchange are stomata and spongy mesophyll tissues.
The stoma comprises of a stomatal pore and two specialized guard cells. The guard cells are structurally adapted by having chloroplasts, thicker, inelastic inner walls and thinner and elastic outer walls.
The stomata mostly opens during the day. They open when the guard cells are turgid.When the guard cells are flaccid, the thinner outer wall shrinks. The inner thicker walls curvature reduces causing the stomata to close.
Answer:
a divergent boundary
Explanation:
a divergent boundary is when two plates pull away or separate, as you can clearly see the arrows are going in different directions.
Answer:
Chemical energy changes into thermal energy and light energy
Answer:
Option B , Binding Energy
Explanation:
The energy in combining two nucleus is lost in binding them. This binding energy is too large that it causes significant loss of mass and is calculated using the Einstein’s theory of relativity.
When two nucleons combine , mass defect is caused which leads to loss of mass associated with energy and therefore the mass of nucleus is less than the mass of nucleons.
Hence, Option B is correct.
