The answer is C) Cloning eliminates the ability to sexually reproduce and provide genetic variability.
In the future, there is no variability in the genes in the clones given that they are the exact copies of the "parent" produce. All should be identical without differences and variations.

<span>The answer is B. The stolon are hyphae that run horizontally and join one sporangiophore (vertically oriented hyphae with sporangia at tips) –with rhizoids as the ‘roots’ - with the other sporangiophore in the fungi population. They are analogous to rhizoids in eukaryotic runner plants. The attached diagram visually demonstrates this <span>description.</span></span>
