The first microscopes were made around:
a) 1965
b) 1665
c) 1950
d) 1776

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

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
