Which structures allow fungi to obtain nutrients they need for survival?

the answer is Hyphae

Explanation:

Hyphae are important structures required for growth in these species, and together, are referred to as mycelium.

it is use for Nutrient absorption from a host, nutrient absorption from soil, trapping structures, and nutrient transportation

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
