1. A. Once developed, a theory cannot be changed.

2. C. A scientific theory is an expression of a mathematical or descriptive

Explanation:

1. Scientific theories can change or develop over time. Because of the development of new technology, scientists are able to explore and discover things which were not possible till now. With new discoveries, some theories are changed, refuted, and/or supported by new evidence.

2. An expression of a mathematical or descriptive relationship observed in nature is actually a scientific law and not a theory. A scientific theory is an explanation of a natural phenomenon while a scienific law is a statement about an observed natural phenomenon and it does not delve into why it occurs.

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
