Answer:

There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.

The best bibliogaphic entry would probably be: Smythe, Clark. <em>Unsinkable: Folly on the Titanic</em> Little, Brown: New York, 1976.

That is because it seems to be a book about the Titanic itself, whereas the other ones have to do with:

  • topics which are less directly related to the subject-matter (the first entry is about maritime laws and the third one is about the animal and plant populations of the lands near the North Pole),
  • personal, relative accounts of the events (like the fourth entry, which is an autobiography of a survivor and therefore describes the wreck through the character's own perspective) as opposed to more factual material.

Describe the role of reproduction in photosynthesis in the carbon oxygen cycle<br>​
exis [7]

Answer:

Photosynthesis provides most of the oxygen that humans and animals breathe. Chlorophyll uses sunlight energy to transform the carbon dioxide and water into oxygen and carbon-based compounds such as glucose, a sugar that helps plants grow.

For macrophytes, photosynthesis in reproductive structures decreases the energy and carbon costs of reproduction to the rest of the plan, which might be more important for iteroparous rather than semelparous organisms.

Hope that helps. x
