<span>d. Not all rainforests are tropical rainforests.</span>
Not all rainforests are tropical rainforests because some are distinguishable from the others and these rainforests has its own designated climate that allows the specific species of plants to grow and thrive in that environment.
Answer: Option (A) is the correct answer.
Explanation:
It is given that the unknown substance is solid at 15 degree celsius. When further heated then heat energy breaks the bond between molecules of the solid.
As a result, temperature remains constant until all the bonds are broken down to convert the solid into liquid.
Hence, the constant 17 degree celsius temperature shows that the solid is melting and after it completely melts then it converts into liquid at 23 degree celsius.
Thus, we can conclude that the statement its melting point is 17 °C, is correct about the unknown substance.
Answer:
All are linked by their common interaction as essential parts of the plant cycle.
Explanation:
The "Carbon Cycle", is most often discussed, because, of its impact on, and effects from atmospheric CO^2 content. The NITROGEN CYCLE is also mentioned frequently, because, of its major role in plant growth. Both nitrogen, and phosphorous are often added to crops as fertilizers; to enhance production of food. This impacts the nitrogen, and phosphorous "Natural Cycles," in much the same way that burning hydrocarbons impacts the carbon cycle. Recognizing the inter-dependencies of the three cycles is also important when considering the possibility of making a change to any one of them.
Hope this helps.
