Which statement BEST describes why mycelium, constructed of hyphae, are necessary for fungi survival?
mariarad [96]

Answer:

Hyphae absorb nutrients from the environment and transport them to other parts of the thallus.

They contain cytoplasm or cell sap. They also contain the nuclei, which include genetic material. Hyphae absorb nutrients from the environment and transport them to other parts of the thallus.

The thallus is the fungus body in which the fungi live or from beneath the soil to give support to the fungi for its growth and its survival.

Answer:

\boxed {\tt 3}

Explanation:

An element only has <u>one</u> type of atom and cannot be broken down by chemical means.

Let's analyze the answer choices.

1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.

2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.

3. This has one type of atoms, so it is an element.  

Therefore the best answer choice is 3.
