Why is RNA necessary to act as a messenger? Why can't the code be taken directly from the DNA?
RNA acts like a messenger because it transfers the codes for the DNA since DNA is too big to fit through the nuclear pores

What is the Greenhouse Effect?

What is the difference between ectoparasite and endoparasite?
Ectoparasites are parasites that explore the external surface of the host (like, for example, mites that parasite the skin). Endoparasites are parasites that live within the body of the host (like the taenias).
