Explain in detail how changes in light intensity or carbon dioxide levels might change rates of photosynthesis.

As a small change in a person's dna can cause a genetic disorder

Dna, in the nucleus carries the genetic code for making proteins in ribosomes. in the diagram, b, represents the proteins produced. dna cannot leave the nucleus to carry the genetic information to the ribosome where proteins are produced. how does the genetic code get from the nucleus to the ribosome? what does a represent? now

When fossil fuels are burned, carbon dioxide is released. how does this gas impact the environment?
