How do nucleotides provide nucleic acids with specific codes? HINT: Think about the structure of nucleotides and the different types of bases found in them.

Nucleotides have specific sequences. When these codes/orders of nucleotides are translated, they code for amino acids, which in turn correspond to specific proteins being made. These proteins are responsible for carrying out various bodily functions.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
